1
00:00:00,040 --> 00:00:02,680
Hey, everyone, welcome back. 
You know, law school, right? 

2
00:00:03,480 --> 00:00:05,600
It feels like you're always 
trying to keep up with all these

3
00:00:05,600 --> 00:00:07,640
new legal concepts. 
And it can be a lot. 

4
00:00:07,640 --> 00:00:08,720
Oh. 
Absolutely. 

5
00:00:08,720 --> 00:00:10,480
It can definitely feel 
overwhelming. 

6
00:00:11,320 --> 00:00:13,800
Well, today we're tackling a 
concept that's not just 

7
00:00:13,800 --> 00:00:17,440
important for torts and criminal
law, but really for, like, every

8
00:00:17,440 --> 00:00:18,640
area of law. 
Yeah. 

9
00:00:18,680 --> 00:00:20,080
Causation. 
Yeah, you got it. 

10
00:00:20,160 --> 00:00:22,920
Causation. 
It might seem pretty simple at 

11
00:00:22,920 --> 00:00:26,000
first glance, but trust me, it 
gets really complicated. 

12
00:00:26,200 --> 00:00:28,560
And for anyone who wants to be a
lawyer, understanding how 

13
00:00:28,560 --> 00:00:32,439
causation works is key. 
And we're talking about doing 

14
00:00:32,439 --> 00:00:35,600
well in law school, passing the 
bar exam, and just building a 

15
00:00:35,600 --> 00:00:38,160
really solid base for your legal
career. 

16
00:00:38,520 --> 00:00:41,320
So let's break it down. 
When we talk about causation in 

17
00:00:41,320 --> 00:00:43,920
law, what exactly are we talking
about? 

18
00:00:44,120 --> 00:00:46,200
Basically, we're talking about 
the connection between an 

19
00:00:46,200 --> 00:00:49,160
action, or, you know, in action 
and the harm that comes after. 

20
00:00:49,160 --> 00:00:51,680
Like if the harm wouldn't have 
happened without the defendant 

21
00:00:52,000 --> 00:00:54,360
doing something or not doing 
something, then you've got 

22
00:00:54,360 --> 00:00:56,240
causation. 
This is what's called factual 

23
00:00:56,240 --> 00:00:58,520
causation. 
So it's about proving that 

24
00:00:58,520 --> 00:01:01,800
direct link between an action 
and its consequences. 

25
00:01:01,800 --> 00:01:03,600
Yeah, like an unbroken chain of 
events. 

26
00:01:03,720 --> 00:01:05,840
Exactly. 
Think of it like a chain 

27
00:01:05,840 --> 00:01:08,480
reaction. 
You know, to prove causation, 

28
00:01:08,480 --> 00:01:11,880
you've got to show that whole 
chain, how one event led to the 

29
00:01:11,880 --> 00:01:14,840
next led to the harm. 
Our sources use a couple of 

30
00:01:14,840 --> 00:01:18,400
examples that make this crystal 
clear, like the classic case of 

31
00:01:18,400 --> 00:01:20,360
a driver running a red light. 
Right. 

32
00:01:20,640 --> 00:01:23,880
If that driver causes a crash 
and someone's hurt, it's usually

33
00:01:23,880 --> 00:01:26,360
pretty obvious. 
But for them running that red 

34
00:01:26,360 --> 00:01:28,120
light, the injuries wouldn't 
have happened. 

35
00:01:28,120 --> 00:01:30,440
It's pretty straightforward. 
And they give another example, 

36
00:01:30,440 --> 00:01:34,840
this one from criminal law. 
Say someone starts a fire and 

37
00:01:34,840 --> 00:01:37,120
then tragically someone dies in 
that fire. 

38
00:01:37,160 --> 00:01:39,640
Yeah, in that case, the 
prosecution would have to prove 

39
00:01:39,640 --> 00:01:42,520
beyond a reasonable to doubt 
that the victim would still be 

40
00:01:42,520 --> 00:01:45,000
alive if it weren't for the 
person who set the fire. 

41
00:01:45,400 --> 00:01:48,520
That direct link is super 
important to prove. 

42
00:01:48,680 --> 00:01:51,840
Now, what about those cases 
where it's not just one person 

43
00:01:51,840 --> 00:01:54,000
or one event that led to the 
harm? 

44
00:01:54,280 --> 00:01:56,800
Like what if there are multiple 
factors at play? 

45
00:01:57,040 --> 00:01:59,360
That's where it gets a little 
more complicated for sure. 

46
00:01:59,360 --> 00:02:02,120
You're talking about something 
called concurrent causation. 

47
00:02:02,360 --> 00:02:06,240
Basically, it recognizes that 
sometimes multiple actions can 

48
00:02:06,240 --> 00:02:10,840
come together to cause harm, 
even if each action on its own 

49
00:02:11,120 --> 00:02:14,240
like wouldn't have been enough. 
Our sources use the example of 

50
00:02:14,240 --> 00:02:16,600
pollution. 
Let's say there are two 

51
00:02:16,600 --> 00:02:20,000
factories, and they're both 
dumping waste into a river. 

52
00:02:20,440 --> 00:02:23,320
That pollution then harms the 
environment downstream. 

53
00:02:23,320 --> 00:02:25,920
Exactly. 
It's tough to say for sure which

54
00:02:25,920 --> 00:02:29,400
factory alone caused all the 
harm, but with this idea of 

55
00:02:29,400 --> 00:02:32,560
concurrent causation, they could
both be held responsible because

56
00:02:32,560 --> 00:02:35,880
their actions, you know, 
together led to the problem. 

57
00:02:36,000 --> 00:02:37,960
Got it. 
So it's not about trying to 

58
00:02:37,960 --> 00:02:40,720
figure out who caused the most 
harm, but just acknowledging 

59
00:02:40,720 --> 00:02:42,760
that both contributed to the bad
outcome. 

60
00:02:42,760 --> 00:02:44,960
Precisely. 
Concurrent causation helps make 

61
00:02:44,960 --> 00:02:47,240
sure that someone is held 
accountable even when it's tough

62
00:02:47,240 --> 00:02:49,600
to say exactly who did what. 
That makes sense. 

63
00:02:50,120 --> 00:02:52,320
OK, so we've talked about 
factual causation. 

64
00:02:52,800 --> 00:02:56,360
What about this other key 
element of causation, proximate 

65
00:02:56,360 --> 00:02:58,480
causation? 
This one seems a lot less 

66
00:02:58,480 --> 00:03:00,320
straightforward. 
Absolutely. 

67
00:03:00,560 --> 00:03:03,240
Proximate causation is all about
foreseeability. 

68
00:03:03,240 --> 00:03:07,400
You have to ask, was the harm 
that happened a foreseeable 

69
00:03:07,400 --> 00:03:09,520
result of what the defendant 
did? 

70
00:03:09,800 --> 00:03:13,080
It's not just enough that their 
actions played a part, the harm 

71
00:03:13,080 --> 00:03:16,280
has to be something that a 
reasonable person you know could

72
00:03:16,280 --> 00:03:19,400
have seen coming. 
So it's like saying, OK, maybe 

73
00:03:19,400 --> 00:03:22,640
you started this whole chain 
reaction, but could you have 

74
00:03:22,640 --> 00:03:26,320
realistically predicted that it 
would lead to this specific 

75
00:03:26,320 --> 00:03:27,960
outcome? 
Exactly. 

76
00:03:27,960 --> 00:03:31,040
Let me give you an example. 
Imagine someone throws a rock 

77
00:03:31,040 --> 00:03:33,800
and breaks a window. 
Pretty direct and sourceable, 

78
00:03:33,800 --> 00:03:36,160
right? 
But what if that broken window 

79
00:03:36,160 --> 00:03:39,440
scares a bird, and that bird 
then flies into a cyclist, 

80
00:03:39,440 --> 00:03:41,840
causing an accident? 
OK, yeah, I see where you're 

81
00:03:41,840 --> 00:03:43,520
going with this. 
Yeah, the person who threw the 

82
00:03:43,520 --> 00:03:46,720
rock might have technically been
the first domino to fall, but it

83
00:03:46,720 --> 00:03:48,520
would be pretty tough to say. 
They could have foreseen the 

84
00:03:48,520 --> 00:03:50,360
whole cyclist thing happening as
a result. 

85
00:03:50,360 --> 00:03:52,840
Exactly. 
That's where proximate causation

86
00:03:52,840 --> 00:03:54,760
steps in. 
The law doesn't hold people 

87
00:03:54,760 --> 00:03:57,240
responsible for absolutely 
everything that could possibly 

88
00:03:57,240 --> 00:03:59,880
happen as a result of what they 
do, only for the things that are

89
00:03:59,880 --> 00:04:03,240
like, reasonably foreseeable. 
This reminds me of that super 

90
00:04:03,240 --> 00:04:06,800
famous law school case Paul's 
Graph V Long Island Railroad. 

91
00:04:07,240 --> 00:04:10,600
Our sources talk about it too. 
It's all about this wild chain 

92
00:04:10,600 --> 00:04:13,440
of events and that whole idea of
foreseeability. 

93
00:04:13,440 --> 00:04:17,079
Oh, Paul's graph, right? 
It's classic for a reason, and I

94
00:04:17,079 --> 00:04:19,360
think every law student 
remembers it because it shows 

95
00:04:19,360 --> 00:04:23,240
just how tricky proximate 
causation can get. 

96
00:04:23,600 --> 00:04:26,360
So for anyone who hasn't heard 
about it, a passenger is trying 

97
00:04:26,360 --> 00:04:29,200
to board a train with a package 
of fireworks, and one of the 

98
00:04:29,200 --> 00:04:30,720
railroad employees tries to help
him. 

99
00:04:31,680 --> 00:04:34,600
Well, the package falls, the 
fireworks go off, and all that 

100
00:04:34,600 --> 00:04:38,200
chaos causes a heavy scale at 
the other end of the platform to

101
00:04:38,200 --> 00:04:40,840
fall and injure Missus Paul's 
graph, who was just like 

102
00:04:40,920 --> 00:04:43,560
standing there. 
It's a wild sequence of events, 

103
00:04:43,560 --> 00:04:45,880
totally. 
But the court ended up saying 

104
00:04:45,880 --> 00:04:48,920
that the railroad wasn't liable 
for Missus Pop Graf's injuries 

105
00:04:49,200 --> 00:04:51,040
because they weren't a 
foreseeable result of what the 

106
00:04:51,040 --> 00:04:53,280
employee did. 
It's hard to imagine that 

107
00:04:53,280 --> 00:04:56,080
helping someone with a package 
would lead to a scale falling on

108
00:04:56,080 --> 00:04:58,040
someone all the way across the 
platform. 

109
00:04:58,240 --> 00:05:01,360
So Paul's graph is like the 
perfect example of how even if 

110
00:05:01,360 --> 00:05:04,360
there's a clear chain of events,
proving proximate causation 

111
00:05:04,360 --> 00:05:07,680
means you have to show that the 
harm was a reasonably 

112
00:05:07,680 --> 00:05:10,080
predictable outcome of the 
defendant's actions. 

113
00:05:10,560 --> 00:05:13,200
It really highlights how 
important that concept of 

114
00:05:13,200 --> 00:05:16,800
foreseeability is in figuring 
out who's legally responsible. 

115
00:05:16,960 --> 00:05:19,400
Exactly. 
Proximate causation helps make 

116
00:05:19,400 --> 00:05:23,040
sure that liability is fair and 
just, considering not just what 

117
00:05:23,040 --> 00:05:26,040
did happen, but what was 
reasonably foreseeable. 

118
00:05:26,120 --> 00:05:28,600
OK, now let's look at how these 
principles actually work in 

119
00:05:28,600 --> 00:05:31,640
specific areas of law. 
Let's start with tort law. 

120
00:05:31,920 --> 00:05:35,240
So in tort law, we're talking 
about those civil wrongs, like 

121
00:05:35,240 --> 00:05:37,960
negligence. 
To prove someone was negligent, 

122
00:05:37,960 --> 00:05:41,120
you have to show four things. 
They had a duty, they breached 

123
00:05:41,120 --> 00:05:43,960
that duty, their actions caused 
harm, and there were actual 

124
00:05:43,960 --> 00:05:46,560
damages. 
Caugation is that key link 

125
00:05:46,560 --> 00:05:49,640
between someone messing up and 
the actual harm that happened. 

126
00:05:49,640 --> 00:05:52,680
So even if someone did something
wrong, you still have to prove 

127
00:05:52,680 --> 00:05:55,160
that what they did caused the 
harm you experienced. 

128
00:05:55,440 --> 00:05:58,080
You got it. 
And remember, we need both 

129
00:05:58,080 --> 00:06:02,360
factual and proximate causation.
Factual shows their actions were

130
00:06:02,360 --> 00:06:06,080
part of the chain and proximate 
ensures the harm was, you know, 

131
00:06:06,160 --> 00:06:08,440
a foreseeable result. 
Think of it like building a 

132
00:06:08,440 --> 00:06:11,000
bridge. 
Both types of causation are the 

133
00:06:11,000 --> 00:06:13,960
supports holding it up. 
Our sources give us an example 

134
00:06:13,960 --> 00:06:15,760
from medical malpractice, which 
is a good one. 

135
00:06:16,040 --> 00:06:19,240
Let's say a doctor makes a 
mistake during surgery and it 

136
00:06:19,240 --> 00:06:21,800
makes a patient's existing 
condition even worse. 

137
00:06:21,880 --> 00:06:25,120
Yeah, that's where concurrent 
causation could definitely come 

138
00:06:25,120 --> 00:06:27,280
in. 
The doctor's negligence might 

139
00:06:27,280 --> 00:06:29,840
not be the only reason the 
patient's worse off, but it 

140
00:06:29,840 --> 00:06:32,400
definitely played a part, along 
with whatever condition they 

141
00:06:32,400 --> 00:06:34,400
already had. 
So the original cause of the 

142
00:06:34,400 --> 00:06:37,080
condition and the doctor could 
both be held liable. 

143
00:06:37,200 --> 00:06:41,480
Exactly, and this idea of shared
responsibility can get even more

144
00:06:41,480 --> 00:06:44,400
complex when you add in 
intervening and superseding 

145
00:06:44,400 --> 00:06:45,400
causes. 
OK. 

146
00:06:45,440 --> 00:06:46,600
Now those are some important 
terms. 

147
00:06:46,600 --> 00:06:49,560
Can you break those down for us?
Think of an intervening cause 

148
00:06:49,560 --> 00:06:51,600
like a detour on the way to the 
harm. 

149
00:06:52,040 --> 00:06:54,560
It happens after the defendant 
does whatever they did, and it 

150
00:06:54,560 --> 00:06:57,120
adds to the harm, but it doesn't
totally break the chain of 

151
00:06:57,120 --> 00:06:59,920
causation. 
So imagine someone you know 

152
00:06:59,920 --> 00:07:02,280
leaves a banana peel on the 
floor being careless. 

153
00:07:02,560 --> 00:07:04,560
Someone slips on it and they 
break their wrist. 

154
00:07:04,720 --> 00:07:05,480
Right, that makes. 
Sense. 

155
00:07:05,480 --> 00:07:08,840
Now picture this while that 
person is waiting to get help. 

156
00:07:09,360 --> 00:07:15,200
A ceiling fan like malfunctions 
and falls down and hurts their 

157
00:07:15,200 --> 00:07:17,920
leg too. 
That falling fan is an 

158
00:07:17,920 --> 00:07:21,920
intervening 'cause it made the 
harm worse, but it doesn't erase

159
00:07:21,920 --> 00:07:24,680
that original negligence of 
leaving the banana peel there. 

160
00:07:24,680 --> 00:07:26,880
Got it. 
So what's a superseding 'cause 

161
00:07:26,880 --> 00:07:28,200
then? 
That's a whole different ball 

162
00:07:28,200 --> 00:07:29,320
game. 
It's such a random, 

163
00:07:29,320 --> 00:07:32,080
unpredictable event that it 
completely wipes out that chain 

164
00:07:32,080 --> 00:07:34,000
of causation. 
Let's go back to our banana 

165
00:07:34,000 --> 00:07:35,840
peel. 
Let's say while the person is 

166
00:07:35,840 --> 00:07:38,760
waiting, an earthquake hits a 
wall, falls down and hurts them 

167
00:07:38,760 --> 00:07:40,440
even more. 
Wow, that's intense. 

168
00:07:40,840 --> 00:07:42,880
So that earthquake would be a 
superseding cause. 

169
00:07:43,120 --> 00:07:45,680
Exactly. 
It's so extraordinary, so 

170
00:07:45,680 --> 00:07:49,600
unforeseeable, that whoever left
the banana peel isn't liable for

171
00:07:49,600 --> 00:07:51,600
anything that happened because 
of the earthquake. 

172
00:07:52,200 --> 00:07:55,680
The law gets that it wouldn't be
fair to hold someone responsible

173
00:07:55,680 --> 00:07:57,240
for something like an act of 
God. 

174
00:07:57,440 --> 00:07:59,320
This is making a lot more sense 
now. 

175
00:07:59,480 --> 00:08:02,280
So how does all this work in 
criminal law, where the stakes 

176
00:08:02,280 --> 00:08:05,520
are even higher? 
The main ideas are similar, but 

177
00:08:05,520 --> 00:08:08,440
in criminal cases it's way 
harder to prove. 

178
00:08:08,720 --> 00:08:11,640
Prosecutors have to prove 
causation beyond a reasonable 

179
00:08:11,640 --> 00:08:13,000
doubt. 
Think of something like 

180
00:08:13,000 --> 00:08:15,560
manslaughter, where someone is 
driving recklessly and they 

181
00:08:15,560 --> 00:08:18,360
cause a fatal accident. 
OK, so we've got someone 

182
00:08:18,360 --> 00:08:21,160
speeding, weaving through 
traffic, and ultimately someone 

183
00:08:21,160 --> 00:08:23,600
dies. 
What would the prosecution have 

184
00:08:23,600 --> 00:08:27,880
to prove to establish causation?
They'd have to prove beyond a 

185
00:08:27,880 --> 00:08:30,800
reasonable doubt both factual 
and proximate causation. 

186
00:08:31,000 --> 00:08:33,280
For factual, they'd have to show
the death wouldn't have 

187
00:08:33,280 --> 00:08:36,720
happened, but for the reckless 
driving, proximate causation 

188
00:08:36,720 --> 00:08:39,559
means showing the death was a 
foreseeable result of that 

189
00:08:39,559 --> 00:08:41,880
reckless driving. 
So it's not just about showing 

190
00:08:41,880 --> 00:08:44,280
they were breaking the law, it's
about connecting those actions 

191
00:08:44,280 --> 00:08:48,280
directly to the death with like 
0 room for doubt. 

192
00:08:48,360 --> 00:08:50,600
Exactly. 
And just like in tort law, 

193
00:08:50,600 --> 00:08:52,960
things can get more complicated 
when you've got intervening 

194
00:08:52,960 --> 00:08:55,240
acts. 
What if someone gets punched in 

195
00:08:55,240 --> 00:08:57,240
a fight, falls and hits their 
head? 

196
00:08:57,640 --> 00:09:00,240
They die a few days later, but 
not directly from the punch. 

197
00:09:00,800 --> 00:09:03,920
The actual cause of death is 
like complications from 

198
00:09:04,040 --> 00:09:07,000
negligent medical treatment. 
So the question is whether the 

199
00:09:07,000 --> 00:09:11,000
person who threw the punch is 
still responsible even though 

200
00:09:11,000 --> 00:09:13,160
the medical treatment was bad. 
It is, yeah. 

201
00:09:13,640 --> 00:09:15,720
And here's where foreseeability 
comes back in. 

202
00:09:16,240 --> 00:09:18,560
Was it foreseeable that the 
punch would lead to someone 

203
00:09:18,560 --> 00:09:20,800
needing medical treatment, and 
that there was a chance that 

204
00:09:20,800 --> 00:09:23,480
treatment could be negligent? 
That's a tricky. 

205
00:09:23,520 --> 00:09:27,480
One, it really seems like 
causation is rarely a simple yes

206
00:09:27,480 --> 00:09:30,320
or no answer. 
There are just so many nuances 

207
00:09:30,320 --> 00:09:32,400
to consider, especially when 
you've got those intervening 

208
00:09:32,400 --> 00:09:34,840
acts or multiple things 
contributing to the harm. 

209
00:09:35,000 --> 00:09:37,880
Absolutely, and that's what 
makes these cases so interesting

210
00:09:37,880 --> 00:09:41,680
and often pretty tough. 
Real life situations are never 

211
00:09:41,680 --> 00:09:44,360
as neat and tidy as what we 
talked about in law school. 

212
00:09:44,720 --> 00:09:47,000
And Speaking of real life 
complications, our sources 

213
00:09:47,000 --> 00:09:50,040
mentioned that proving causation
can be super difficult in cases 

214
00:09:50,040 --> 00:09:54,640
involving environmental damage, 
toxic torts, and situations 

215
00:09:54,640 --> 00:09:57,240
where it's just hard to say 
exactly who's responsible. 

216
00:09:57,240 --> 00:09:59,600
Yeah, those are the kind of 
cases that really make you think

217
00:09:59,600 --> 00:10:01,880
hard about how we understand 
causation. 

218
00:10:02,240 --> 00:10:04,960
Imagine a whole community where 
people have been exposed to 

219
00:10:04,960 --> 00:10:08,720
pollution from lots of different
places over many years, and now 

220
00:10:08,720 --> 00:10:09,960
they're getting sick. 
Oh wow. 

221
00:10:10,640 --> 00:10:13,240
Yeah, it would be almost 
impossible to say for sure which

222
00:10:13,240 --> 00:10:17,120
specific thing caused each 
person's illness, or even which 

223
00:10:17,120 --> 00:10:19,840
company is to blame. 
It'd be like trying to find, I 

224
00:10:19,840 --> 00:10:22,640
don't know, a specific drop of 
water back to its source in the 

225
00:10:22,640 --> 00:10:24,600
ocean. 
Great analogy. 

226
00:10:24,600 --> 00:10:27,800
And that's the kind of challenge
that lawyers and scientists face

227
00:10:27,800 --> 00:10:31,080
in these environmental cases. 
They have to rely on statistics,

228
00:10:31,080 --> 00:10:34,600
studies of how diseases spread 
and expert opinions just to try 

229
00:10:34,600 --> 00:10:37,080
and show a link between the 
pollution and the harm. 

230
00:10:37,400 --> 00:10:40,320
So what happens when you just 
can't say for sure exactly where

231
00:10:40,320 --> 00:10:43,480
the harm came from? 
Even with all that evidence, our

232
00:10:43,480 --> 00:10:46,160
sources mentioned something 
called market share liability. 

233
00:10:46,360 --> 00:10:49,440
Oh yeah, that's a really cool 
legal idea that came out of a 

234
00:10:49,440 --> 00:10:52,160
landmark case, Syndell V Abbott 
Laboratories. 

235
00:10:52,880 --> 00:10:57,680
The case was about this drug 
DES, which doctors used to give 

236
00:10:57,680 --> 00:10:59,680
to pregnant women to prevent 
miscarriages. 

237
00:11:00,200 --> 00:11:03,240
Turns out it ended up causing 
cancer in their daughters later 

238
00:11:03,240 --> 00:11:05,960
on. 
The problem was tons of 

239
00:11:05,960 --> 00:11:08,920
companies were making DES so the
women couldn't tell which 

240
00:11:08,920 --> 00:11:10,920
company made the pills their 
mothers took. 

241
00:11:11,440 --> 00:11:12,680
So how did the court deal with 
that? 

242
00:11:12,680 --> 00:11:15,320
It wouldn't be fair to let all 
the companies off the hook just 

243
00:11:15,320 --> 00:11:18,520
because no one could trace the 
harm back to one specific 

244
00:11:18,520 --> 00:11:19,920
source. 
Right, totally. 

245
00:11:19,920 --> 00:11:22,600
So they came up with this idea, 
market share liability. 

246
00:11:22,600 --> 00:11:25,320
They said each company was 
responsible for a portion of the

247
00:11:25,320 --> 00:11:29,000
damages based on how much of the
DES market they controlled back 

248
00:11:29,000 --> 00:11:32,280
then. 
So if a company sold, say, 20% 

249
00:11:32,280 --> 00:11:35,800
of the DES, they'd have to pay 
20% of the damages even if there

250
00:11:35,800 --> 00:11:38,400
was no direct proof that their 
pills caused the harm. 

251
00:11:38,440 --> 00:11:40,880
Exactly. 
It was this groundbreaking 

252
00:11:40,880 --> 00:11:43,920
solution to make sure that 
victims got some compensation 

253
00:11:44,040 --> 00:11:46,920
even when the usual rules of 
causation were like, impossible 

254
00:11:46,920 --> 00:11:48,640
to follow. 
It's kind of amazing how the 

255
00:11:48,640 --> 00:11:51,360
legal system can change and 
adapt to these really complex 

256
00:11:51,360 --> 00:11:55,520
issues and find ways to ensure 
justice even in situations where

257
00:11:55,520 --> 00:11:57,360
it seems impossible. 
It really is. 

258
00:11:57,440 --> 00:12:00,360
It shows how creative legal 
minds can be and how important 

259
00:12:00,360 --> 00:12:03,000
it is to keep pursuing fairness 
and making sure someone's held 

260
00:12:03,000 --> 00:12:05,400
accountable. 
We've covered a ton today, from 

261
00:12:05,400 --> 00:12:09,920
the basic ideas behind causation
to some really nuanced examples 

262
00:12:09,920 --> 00:12:13,080
and important court decisions. 
We have, but there's still more 

263
00:12:13,080 --> 00:12:15,760
to dive into. 
Welcome back everyone. 

264
00:12:15,760 --> 00:12:17,440
Ready to jump back into 
causation? 

265
00:12:17,440 --> 00:12:20,440
Definitely great. 
Let's focus on a specific area 

266
00:12:20,440 --> 00:12:24,400
where causation is super 
important, medical malpractice. 

267
00:12:24,840 --> 00:12:27,960
These cases can get pretty 
complex, especially when you 

268
00:12:27,960 --> 00:12:30,920
start dealing with medical 
evidence and expert witnesses. 

269
00:12:30,920 --> 00:12:33,760
Oh yeah, I remember when I first
started learning about medical 

270
00:12:33,760 --> 00:12:36,520
malpractice in law school. 
It was a little intimidating to 

271
00:12:36,520 --> 00:12:38,360
be honest. 
Sometimes it feels like you need

272
00:12:38,360 --> 00:12:40,920
a medical degree on top of your 
law degree just to keep up. 

273
00:12:41,160 --> 00:12:43,400
I know what you mean, it can 
feel like you're learning a 

274
00:12:43,400 --> 00:12:46,960
whole new language. 
But the important thing is, even

275
00:12:46,960 --> 00:12:51,320
in these really complex cases, 
the same basic principles of 

276
00:12:51,320 --> 00:12:54,520
causation still apply. 
You still have to show that the 

277
00:12:54,520 --> 00:12:57,600
harm wouldn't have happened but 
for the healthcare providers 

278
00:12:57,600 --> 00:13:00,560
negligence. 
So it's not enough to just say a

279
00:13:00,560 --> 00:13:04,200
doctor messed up, you have to 
actually prove that their 

280
00:13:04,200 --> 00:13:07,520
mistake caused the patient's 
injury or made their condition 

281
00:13:07,520 --> 00:13:08,520
worse. 
You got it. 

282
00:13:08,800 --> 00:13:12,040
Let's say, for example, a 
patient has surgery and ends up 

283
00:13:12,040 --> 00:13:14,640
with a really bad infection. 
You can't just point to the 

284
00:13:14,640 --> 00:13:16,880
infection and say, look, 
something obviously went wrong. 

285
00:13:17,200 --> 00:13:20,280
You have to actually prove that 
the infection happened because 

286
00:13:20,280 --> 00:13:23,520
the surgeon was negligent. 
Maybe they didn't follow proper 

287
00:13:23,520 --> 00:13:26,480
procedures to keep things 
sterile, or maybe they messed up

288
00:13:26,480 --> 00:13:28,840
with the antibiotics. 
So you have to connect the dots,

289
00:13:28,840 --> 00:13:31,600
show that the negligence 
directly led to the harm. 

290
00:13:31,760 --> 00:13:36,240
Exactly, and a lot of times this
means you need expert testimony 

291
00:13:36,240 --> 00:13:37,720
from other medical 
professionals. 

292
00:13:37,960 --> 00:13:40,080
They can explain what the 
standard of care is supposed to 

293
00:13:40,080 --> 00:13:42,520
be, look over medical records, 
and give their professional 

294
00:13:42,520 --> 00:13:44,800
opinion on whether the defendant
actually messed up. 

295
00:13:45,040 --> 00:13:47,440
It's like you need someone to 
translate between the legal 

296
00:13:47,440 --> 00:13:50,760
world and the medical world. 
That's a great way to put it. 

297
00:13:51,480 --> 00:13:54,480
Things can get even trickier 
when the patient already had a 

298
00:13:54,480 --> 00:13:57,120
condition that might have also 
played a role in the harm. 

299
00:13:57,720 --> 00:14:00,880
Like imagine a patient who has a
heart condition, goes in for a 

300
00:14:00,880 --> 00:14:04,240
routine procedure, and then bam,
they have a heart attack during 

301
00:14:04,240 --> 00:14:07,160
the procedure. 
So in a case like that, you'd 

302
00:14:07,160 --> 00:14:08,880
have to figure out if the heart 
attack would have happened 

303
00:14:08,880 --> 00:14:10,840
anyway, even without the 
procedure. 

304
00:14:11,080 --> 00:14:13,080
Right. 
The court would need to look at 

305
00:14:13,080 --> 00:14:16,400
everything really carefully and 
decide if what the healthcare 

306
00:14:16,400 --> 00:14:19,880
provider did was a substantial 
factor in causing the heart 

307
00:14:19,880 --> 00:14:22,800
attack, even though the patient 
was already at higher risk 

308
00:14:22,800 --> 00:14:24,080
because of their heart 
condition. 

309
00:14:24,080 --> 00:14:27,040
It's like trying to figure out 
which domino and a whole line of

310
00:14:27,040 --> 00:14:29,680
dominoes was the one that 
actually tipped everything over.

311
00:14:29,680 --> 00:14:32,720
Exactly, and that's another 
reason why expert testimony is 

312
00:14:32,720 --> 00:14:36,000
so crucial in these cases. 
Experts can help the court 

313
00:14:36,000 --> 00:14:39,880
really understand the connection
or lack of connection between 

314
00:14:39,880 --> 00:14:43,360
the pre-existing condition, the 
medical procedure and what 

315
00:14:43,360 --> 00:14:44,880
ultimately happened to the 
patient. 

316
00:14:45,080 --> 00:14:47,840
Now, our sources mentioned this 
idea called the loss of chance 

317
00:14:47,840 --> 00:14:51,520
doctrine, which seems especially
important in medical malpractice

318
00:14:51,520 --> 00:14:56,400
cases where a delayed diagnosis 
or a wrong diagnosis might have 

319
00:14:56,400 --> 00:14:59,320
cost the patient precious time 
and treatment options. 

320
00:14:59,320 --> 00:15:01,360
Oh yeah, the loss of chance 
doctrine. 

321
00:15:01,360 --> 00:15:03,240
It's a really interesting legal 
idea. 

322
00:15:03,480 --> 00:15:07,080
It basically says that even if 
negligence doesn't directly lead

323
00:15:07,080 --> 00:15:10,200
to someone dying or getting 
injured, it can still cause 

324
00:15:10,200 --> 00:15:12,640
harm. 
It's about the loss of a chance 

325
00:15:12,640 --> 00:15:15,360
for a better outcome. 
Like, think about a Doctor Who 

326
00:15:15,360 --> 00:15:17,480
misses a cancer diagnosis early 
on. 

327
00:15:18,120 --> 00:15:20,360
By the time they catch it, it's 
way more advanced and the 

328
00:15:20,360 --> 00:15:22,680
patient's chances of survival 
have plummeted. 

329
00:15:23,000 --> 00:15:25,880
So even though the doctor didn't
cause the cancer, their 

330
00:15:25,880 --> 00:15:28,080
negligence took away the 
patient's chance to get 

331
00:15:28,080 --> 00:15:30,080
treatment when it would have 
been most effective. 

332
00:15:30,280 --> 00:15:33,200
Precisely the loss of chance 
doctor and let's patients get 

333
00:15:33,200 --> 00:15:35,840
damages for that lost 
opportunity, even if they can't 

334
00:15:35,840 --> 00:15:39,000
prove for sure that they would 
have definitely survived if the 

335
00:15:39,000 --> 00:15:42,360
diagnosis had been made earlier.
So it's not just about physical 

336
00:15:42,360 --> 00:15:45,920
harm, it's also about the loss 
of hope and the potential for 

337
00:15:45,920 --> 00:15:47,360
things to have turned out 
differently. 

338
00:15:47,560 --> 00:15:50,040
Exactly. 
It acknowledges that medical 

339
00:15:50,040 --> 00:15:53,880
negligence can have consequences
that go way beyond just the 

340
00:15:53,880 --> 00:15:56,720
immediate physical harm. 
I think it's time to talk about 

341
00:15:56,720 --> 00:15:59,840
some of the big cases that have 
really shaped our understanding 

342
00:15:59,840 --> 00:16:02,960
of medical malpractice. 
Our sources talk about Barnett V

343
00:16:02,960 --> 00:16:05,640
Chelsea and Kensington Hospital,
which seems like a really good 

344
00:16:05,640 --> 00:16:08,920
example. 
Ah, yes, Barnett, it's a classic

345
00:16:08,920 --> 00:16:11,640
case and it really highlights 
the importance of that. 

346
00:16:12,000 --> 00:16:16,440
But for test we talked about so 
in Barnett this guy goes to the 

347
00:16:16,440 --> 00:16:20,520
hospital after drinking tea that
was get this laced with arsenic.

348
00:16:20,720 --> 00:16:23,120
The hospital staff didn't 
examine him properly and sent 

349
00:16:23,120 --> 00:16:25,680
him home. 
Sadly, he died from arsenic 

350
00:16:25,680 --> 00:16:28,160
poisoning. 
So at first glance it seems like

351
00:16:28,160 --> 00:16:31,520
a pretty clear cut case. 
The hospital messed up and the 

352
00:16:31,520 --> 00:16:34,400
patient died. 
There's a twist, right? 

353
00:16:34,400 --> 00:16:36,680
There is. 
It turned out that even if the 

354
00:16:36,680 --> 00:16:38,920
hospital had done everything 
right, the guy still would have 

355
00:16:38,920 --> 00:16:41,720
died from the arsenic poisoning.
He just drank way too much of 

356
00:16:41,720 --> 00:16:43,240
it. 
Oh wow, so even though the 

357
00:16:43,240 --> 00:16:46,080
hospital was negligent, it 
didn't actually change the final

358
00:16:46,080 --> 00:16:47,560
outcome? 
Exactly. 

359
00:16:47,800 --> 00:16:50,280
The court said that the man's 
death would happened anyway 

360
00:16:50,280 --> 00:16:52,920
regardless of what the hospital 
did, so they weren't liable. 

361
00:16:53,480 --> 00:16:56,400
Barnett shows us that even when 
it seems obvious that someone 

362
00:16:56,400 --> 00:16:59,280
was negligent, you still have to
prove causation. 

363
00:16:59,960 --> 00:17:03,240
It really drives on the point 
that the butt Ford test isn't 

364
00:17:03,240 --> 00:17:05,760
just some legal technicality, 
it's there to make sure things 

365
00:17:05,760 --> 00:17:09,000
are fair and that no one's held 
responsible unless their actions

366
00:17:09,000 --> 00:17:12,000
truly made a difference. 
It is, Barnett teaches us, to 

367
00:17:12,000 --> 00:17:14,560
look beyond the surface and 
really analyze whether the 

368
00:17:14,560 --> 00:17:17,359
negligence was a substantial 
factor in what happened. 

369
00:17:17,480 --> 00:17:20,560
Now let's switch gears a bit and
talk about another landmark case

370
00:17:20,800 --> 00:17:24,280
Wagon Mound number one, that's 
had a huge impact on how we 

371
00:17:24,280 --> 00:17:28,319
understand proximate causation. 
This one involves a ship, an oil

372
00:17:28,319 --> 00:17:30,800
spill, and a pretty surprising 
legal outcome. 

373
00:17:31,120 --> 00:17:35,400
Right, Wagon mound #1 it's a 
classic case for a reason, and 

374
00:17:35,400 --> 00:17:38,720
it helps us understand the idea 
of foreseeability and negligence

375
00:17:38,720 --> 00:17:40,880
cases. 
So picture this. 

376
00:17:41,600 --> 00:17:45,040
A ship spills oil into a harbor 
in Sydney, Australia. 

377
00:17:45,720 --> 00:17:48,680
The oil spreads all over and 
reaches a Wharf where, wouldn't 

378
00:17:48,680 --> 00:17:50,320
you know it, they're doing some 
welding. 

379
00:17:50,960 --> 00:17:54,000
Sparks from the welding ignite 
the oil and boom. 

380
00:17:54,520 --> 00:17:56,920
Big fire. 
Major damage to the Wharf and 

381
00:17:56,920 --> 00:18:00,240
other ships. 
OK, so a negligent oil spill 

382
00:18:00,480 --> 00:18:03,720
leads to a fire and a lot of 
property damage. 

383
00:18:03,840 --> 00:18:05,200
Seems pretty straightforward, 
right? 

384
00:18:05,560 --> 00:18:06,800
Somebody should be held 
responsible. 

385
00:18:06,920 --> 00:18:10,440
You'd think so, but this is 
where foreseeability comes in. 

386
00:18:10,480 --> 00:18:13,080
At the time, people didn't 
really know that oil could catch

387
00:18:13,080 --> 00:18:15,480
fire on water like that under 
those conditions. 

388
00:18:15,640 --> 00:18:18,160
So even though the ship owners 
were negligent in spilling the 

389
00:18:18,160 --> 00:18:20,480
oil, it's not like they could 
have predicted that it would 

390
00:18:20,480 --> 00:18:22,200
lead to a fire and all that 
damage. 

391
00:18:22,200 --> 00:18:24,480
So the court basically said, 
yeah, you messed up, but you 

392
00:18:24,480 --> 00:18:26,520
couldn't have known that that 
specific thing would happen. 

393
00:18:26,640 --> 00:18:28,600
Exactly. 
The court said that the fire 

394
00:18:28,600 --> 00:18:31,680
wasn't a foreseeable consequence
of the oil spill, so the ship 

395
00:18:31,680 --> 00:18:33,960
owners weren't liable for the 
fire damage. 

396
00:18:35,040 --> 00:18:38,560
Wagon mound #1 established this 
really important principle. 

397
00:18:39,400 --> 00:18:43,000
You're only responsible for the 
consequences of your actions 

398
00:18:43,000 --> 00:18:45,880
that are foreseeable, not for 
every single thing that could 

399
00:18:45,880 --> 00:18:47,720
possibly happen. 
That makes sense. 

400
00:18:47,720 --> 00:18:50,720
It means you're not on the hook 
for every crazy, unpredictable 

401
00:18:50,720 --> 00:18:54,320
thing that might result from 
your actions, only the things 

402
00:18:54,320 --> 00:18:56,480
that a reasonable person could 
have anticipated. 

403
00:18:56,480 --> 00:18:58,320
Right. 
It helps prevent people from 

404
00:18:58,320 --> 00:19:01,280
being held liable for absolutely
everything, especially when 

405
00:19:01,280 --> 00:19:03,960
you've got these long, 
complicated chains of events. 

406
00:19:04,280 --> 00:19:07,200
It keeps the law fair and 
proportionate, holding people 

407
00:19:07,200 --> 00:19:09,920
accountable for what they could 
have reasonably foreseen. 

408
00:19:10,440 --> 00:19:13,760
It's amazing how much legal 
thinking has evolved over time 

409
00:19:13,760 --> 00:19:17,000
and how cases like these have 
really shaped our understanding 

410
00:19:17,000 --> 00:19:18,880
of these complicated causation 
issues. 

411
00:19:19,440 --> 00:19:21,640
It's great for anyone who's 
studying law to really dig into 

412
00:19:21,640 --> 00:19:23,200
these cases. 
They really do. 

413
00:19:23,680 --> 00:19:26,200
They show us that it's so 
important not to jump to 

414
00:19:26,200 --> 00:19:29,480
conclusions, to look at all the 
details in each case, and to 

415
00:19:29,480 --> 00:19:32,480
understand that the rules of 
causation can work differently 

416
00:19:32,480 --> 00:19:36,080
depending on the situation. 
Law is rarely black and white, 

417
00:19:36,160 --> 00:19:38,000
especially when it comes to 
causation. 

418
00:19:38,520 --> 00:19:41,120
And Speaking of Gray areas, I 
want to go back to something we 

419
00:19:41,120 --> 00:19:44,960
touched on earlier, the eggshell
skull rule. 

420
00:19:45,240 --> 00:19:47,480
It's always stuck with me 
because it says a lot about like

421
00:19:48,000 --> 00:19:49,960
the ethical side of our legal 
system. 

422
00:19:49,960 --> 00:19:52,960
Yeah, the eggshell skull rule is
definitely a thought provoking 

423
00:19:52,960 --> 00:19:55,320
one. 
It basically says that you take 

424
00:19:55,320 --> 00:19:58,400
your victim as you find them, so
even if someone has a 

425
00:19:58,400 --> 00:20:01,080
pre-existing condition that 
makes them more likely to be 

426
00:20:01,080 --> 00:20:03,960
injured, you're still 
responsible for the full extent 

427
00:20:03,960 --> 00:20:07,000
of the harm you caused. 
So like if someone has really 

428
00:20:07,000 --> 00:20:09,960
brittle bones and I bump into 
them, they break a bone. 

429
00:20:10,320 --> 00:20:13,360
Even though someone else might 
have only gotten a bruise, I'm 

430
00:20:13,360 --> 00:20:14,960
still responsible for that 
broken bone. 

431
00:20:15,000 --> 00:20:18,240
That's right, the eggshell skull
rule keeps people from getting 

432
00:20:18,240 --> 00:20:20,840
away with something just because
the person they harmed was more 

433
00:20:20,840 --> 00:20:23,760
fragile than average. 
It's about recognizing that 

434
00:20:23,760 --> 00:20:26,480
justice shouldn't depend on how 
tough someone is. 

435
00:20:26,640 --> 00:20:28,800
It's like saying you can't 
discriminate against someone 

436
00:20:28,800 --> 00:20:30,120
just because they're more 
delicate. 

437
00:20:30,720 --> 00:20:33,640
You have to own up to the full 
consequences of what you did, 

438
00:20:34,000 --> 00:20:37,200
even if those consequences were 
worse because of something you 

439
00:20:37,200 --> 00:20:39,080
couldn't control. 
That's a really good way to 

440
00:20:39,080 --> 00:20:41,800
think about it. 
The eggshell skull rule shows 

441
00:20:41,800 --> 00:20:44,840
that everyone deserves equal 
protection under the law, no 

442
00:20:44,840 --> 00:20:47,520
matter what conditions or 
vulnerabilities they might have.

443
00:20:47,640 --> 00:20:49,680
It's a powerful message for 
sure. 

444
00:20:50,240 --> 00:20:54,040
It says that justice should be 
fair and equal for everyone, and

445
00:20:54,040 --> 00:20:56,800
that the person who caused the 
harm should be held responsible 

446
00:20:57,000 --> 00:20:59,920
no matter the specific 
circumstances of the person they

447
00:20:59,920 --> 00:21:01,720
harm. 
It all comes back to fairness 

448
00:21:01,720 --> 00:21:04,240
and accountability, which are 
essential parts of our legal 

449
00:21:04,240 --> 00:21:06,480
system. 
It also reminds us that law 

450
00:21:06,480 --> 00:21:09,600
isn't just about following 
rules, it's about upholding 

451
00:21:09,600 --> 00:21:11,880
values and protecting everyone's
rights. 

452
00:21:12,040 --> 00:21:14,120
Now, before we move on, I want 
to touch on something else 

453
00:21:14,120 --> 00:21:17,240
that's super important how 
causation connects with public 

454
00:21:17,240 --> 00:21:19,800
policy. 
Our sources point out that these

455
00:21:19,800 --> 00:21:22,240
causation rules aren't just 
these random legal ideas. 

456
00:21:22,840 --> 00:21:26,800
They reflect and influence what 
we as a society want to achieve.

457
00:21:27,000 --> 00:21:30,280
That's a crucial point. 
When we think about causation, 

458
00:21:30,280 --> 00:21:34,120
it's not just about individual 
cases, it's about how those 

459
00:21:34,120 --> 00:21:38,280
cases affect society as a whole.
So it's not just about saying 

460
00:21:38,280 --> 00:21:41,160
who's to blame in a specific 
situation, it's about thinking 

461
00:21:41,160 --> 00:21:44,560
about the big picture and how 
our decisions about causation 

462
00:21:44,600 --> 00:21:47,160
can shape people's behavior and 
the world we live. 

463
00:21:47,160 --> 00:21:51,160
In exactly, take joint and 
several liability for example. 

464
00:21:51,160 --> 00:21:53,760
We see this a lot in 
environmental cases where you 

465
00:21:53,760 --> 00:21:56,080
have multiple polluters 
contributing to the problem. 

466
00:21:56,080 --> 00:22:00,000
OK, so if you've got like a 
bunch of companies dumping waste

467
00:22:00,000 --> 00:22:02,760
into a river, they could all be 
held responsible for the 

468
00:22:02,760 --> 00:22:06,320
environmental damage, even if we
can't say for sure how much each

469
00:22:06,320 --> 00:22:07,520
company contributed. 
Right. 

470
00:22:07,880 --> 00:22:10,560
And the thinking behind that is 
that it makes companies take 

471
00:22:10,560 --> 00:22:13,640
Environmental Protection more 
seriously and encourages them to

472
00:22:13,640 --> 00:22:15,640
work together to minimize the 
harm. 

473
00:22:15,760 --> 00:22:18,320
Like if you pollute, you're all 
responsible, period. 

474
00:22:18,760 --> 00:22:21,880
It really emphasizes a shared 
responsibility for protecting 

475
00:22:21,880 --> 00:22:23,560
the environment. 
Absolutely. 

476
00:22:23,840 --> 00:22:27,400
Drain and several liability is 
just one example of how we use 

477
00:22:27,400 --> 00:22:30,840
causation to achieve bigger 
goals, like protecting the 

478
00:22:30,840 --> 00:22:34,000
environment or public health. 
It's a way for the legal system 

479
00:22:34,000 --> 00:22:36,640
to promote good behavior and 
protect the common good. 

480
00:22:36,880 --> 00:22:39,960
It shows that the law isn't just
about resolving conflicts, it's 

481
00:22:39,960 --> 00:22:42,560
about actively working to create
a better future. 

482
00:22:43,200 --> 00:22:46,240
It's about finding that balance 
between holding people 

483
00:22:46,240 --> 00:22:50,040
accountable and also thinking 
about the long term consequences

484
00:22:50,040 --> 00:22:52,960
of legal decisions. 
It's a delicate balance for 

485
00:22:52,960 --> 00:22:55,840
sure, but it's crucial for 
having a legal system that's 

486
00:22:55,840 --> 00:22:59,600
both fair and effective. 
And as you move forward in your 

487
00:22:59,600 --> 00:23:02,520
legal careers, it's something to
keep in mind as you tackle 

488
00:23:02,520 --> 00:23:04,720
causation and all these 
different areas of law all. 

489
00:23:05,440 --> 00:23:06,160
Right. 
Welcome back. 

490
00:23:06,840 --> 00:23:08,960
We've talked about a lot with 
causation, but there's still a 

491
00:23:08,960 --> 00:23:12,000
few more areas of law I want to 
touch on where these ideas are 

492
00:23:12,000 --> 00:23:13,480
super relevant. 
Sounds good. 

493
00:23:13,600 --> 00:23:15,600
Let's do it. 
OK, so let's dive into products 

494
00:23:15,600 --> 00:23:17,640
liability. 
This is another area where 

495
00:23:17,640 --> 00:23:20,120
proving causation can get really
tricky. 

496
00:23:20,320 --> 00:23:23,600
We're talking about situations 
where a defective product harm 

497
00:23:23,600 --> 00:23:25,720
someone. 
Right products liability. 

498
00:23:25,920 --> 00:23:28,520
Definitely a challenging area 
when it comes to causation. 

499
00:23:28,760 --> 00:23:32,400
Like if I buy a blender and the 
first time I use it, the blade 

500
00:23:32,400 --> 00:23:35,320
flies off and hurts me. 
It seems pretty obvious that the

501
00:23:35,320 --> 00:23:38,720
blender was defective and caused
the injury, but what happens 

502
00:23:38,720 --> 00:23:41,760
when it's not so clear? 
What if it could have been user 

503
00:23:41,760 --> 00:23:44,000
error or something else 
entirely? 

504
00:23:44,040 --> 00:23:46,960
That's when it gets tough. 
In these cases, you have to 

505
00:23:46,960 --> 00:23:48,880
think about all the possible 
causes. 

506
00:23:49,120 --> 00:23:52,600
You know, design defects, 
manufacturing flaws, bad 

507
00:23:52,600 --> 00:23:55,840
labeling, even failing to warn 
people about potential dangers. 

508
00:23:56,480 --> 00:23:58,480
It's like a detective trying to 
solve the case. 

509
00:23:58,560 --> 00:24:01,600
So you might have to like 
reconstruct accidents, test 

510
00:24:01,600 --> 00:24:04,040
different parts of the product, 
even talk to experts in 

511
00:24:04,040 --> 00:24:08,000
engineering or manufacturing. 
Exactly, and to nail down 

512
00:24:08,000 --> 00:24:11,040
causation you have to show that 
the defect was a substantial 

513
00:24:11,040 --> 00:24:13,640
factor in causing the harm. 
And even if a product is 

514
00:24:13,640 --> 00:24:17,240
defective, the company that made
it might not be liable if the 

515
00:24:17,240 --> 00:24:19,040
harm wasn't something they could
have foreseen, right? 

516
00:24:19,040 --> 00:24:20,160
Right. 
They could definitely argue 

517
00:24:20,160 --> 00:24:22,200
that, yeah. 
But whether that works depends 

518
00:24:22,200 --> 00:24:25,400
on things like, you know, what's
normal in that industry, if 

519
00:24:25,400 --> 00:24:28,400
there have been similar 
incidents with that product and 

520
00:24:28,400 --> 00:24:30,080
if there were safer ways to 
design it. 

521
00:24:30,360 --> 00:24:34,120
So it all comes down to what a 
reasonable manufacturer would 

522
00:24:34,120 --> 00:24:36,000
have known or done in that 
situation. 

523
00:24:36,480 --> 00:24:39,280
That's where things like legal 
precedents and industry 

524
00:24:39,280 --> 00:24:41,120
standards come in, right? 
Definitely. 

525
00:24:41,160 --> 00:24:46,040
Products liability is a mix of 
legal ideas, industry norms, and

526
00:24:46,040 --> 00:24:49,400
scientific evidence, and they're
usually lots of different 

527
00:24:49,400 --> 00:24:52,120
parties involved. 
The manufacturer, the 

528
00:24:52,120 --> 00:24:55,680
distributor, the store that sold
it, even the consumer. 

529
00:24:55,840 --> 00:24:58,720
It's not as simple as just 
pointing fingers at one company.

530
00:24:58,760 --> 00:25:01,480
It makes you think, you know. 
Causation isn't just this 

531
00:25:01,480 --> 00:25:03,360
theoretical thing we learned 
about in law school. 

532
00:25:03,600 --> 00:25:06,720
It has real consequences for 
companies and people in the real

533
00:25:06,720 --> 00:25:08,440
world. 
It does, absolutely. 

534
00:25:08,640 --> 00:25:10,520
Let's move on to environmental 
law now. 

535
00:25:11,160 --> 00:25:13,960
This is another area where 
proving causation is often 

536
00:25:13,960 --> 00:25:16,520
incredibly difficult. 
We're talking about pollution, 

537
00:25:16,800 --> 00:25:20,120
hazardous waste, anything that 
could harm the environment or 

538
00:25:20,120 --> 00:25:22,280
people's health. 
Right, those big class action 

539
00:25:22,280 --> 00:25:25,920
lawsuits about oil spills, 
contaminated water, exposure to 

540
00:25:25,920 --> 00:25:27,640
toxic chemicals, that kind of 
thing. 

541
00:25:27,800 --> 00:25:31,240
Yeah, those cases, it's got to 
be super hard to pinpoint the 

542
00:25:31,240 --> 00:25:33,880
exact source of the harm, 
especially with something like 

543
00:25:33,880 --> 00:25:36,080
air pollution, which can spread 
so far. 

544
00:25:36,560 --> 00:25:40,040
How do you even begin to connect
a specific polluter to the harm?

545
00:25:40,040 --> 00:25:43,000
It's a huge challenge, no doubt.
Imagine a scenario where you 

546
00:25:43,000 --> 00:25:46,160
have several factories along a 
river all releasing pollutants 

547
00:25:46,440 --> 00:25:48,560
and downstream people start 
getting sick. 

548
00:25:48,880 --> 00:25:52,680
How do you know which factory or
if anyone factory is to blame? 

549
00:25:52,880 --> 00:25:56,040
It's like a giant puzzle where 
the pieces are spread out over 

550
00:25:56,040 --> 00:25:58,360
time and space and there could 
be multiple culprits. 

551
00:25:58,560 --> 00:26:01,080
I like that, and that's why in 
environmental cases you often 

552
00:26:01,080 --> 00:26:05,000
have to rely on those big 
epidemiological studies, data 

553
00:26:05,000 --> 00:26:08,720
about air and water quality, and
those really complex models to 

554
00:26:08,720 --> 00:26:11,120
try to connect the pollution to 
the harm. 

555
00:26:11,480 --> 00:26:15,120
It sounds like this area of law 
requires not only legal skills, 

556
00:26:15,200 --> 00:26:18,560
but also a deep understanding of
environmental science. 

557
00:26:18,760 --> 00:26:20,880
You'd have to be comfortable 
with things like toxicology and 

558
00:26:20,880 --> 00:26:23,120
statistics too, right? 
Oh yeah, for sure. 

559
00:26:23,120 --> 00:26:26,240
It's highly specialized. 
And a lot of times these cases 

560
00:26:26,240 --> 00:26:29,720
drag on forever, costing tons of
money because the companies 

561
00:26:29,720 --> 00:26:32,520
involved have all these 
resources to fight back, to 

562
00:26:32,520 --> 00:26:34,840
challenge the scientific 
evidence and say that something 

563
00:26:34,840 --> 00:26:38,760
else caused the harm. 
But for people who really care 

564
00:26:38,760 --> 00:26:41,360
about environmental justice, 
it's really important work. 

565
00:26:41,400 --> 00:26:44,000
It's about holding polluters 
accountable and protecting 

566
00:26:44,000 --> 00:26:47,640
communities and the environment.
It just shows how powerful these

567
00:26:47,640 --> 00:26:51,600
causation principles can be, how
they can be used to create a 

568
00:26:51,600 --> 00:26:53,720
healthier, more sustainable 
world. 

569
00:26:53,800 --> 00:26:56,360
They can. 
OK, ready for one more area of 

570
00:26:56,360 --> 00:26:59,520
law where causation is central? 
Absolutely hit me with it. 

571
00:26:59,560 --> 00:27:02,680
Let's talk about workplace 
accidents and those workers 

572
00:27:02,680 --> 00:27:05,640
compensation claims. 
This is something that affects a

573
00:27:05,640 --> 00:27:09,080
lot of people and understanding 
causation is crucial for both 

574
00:27:09,080 --> 00:27:12,240
workers and employers. 
Yeah, I interned at a firm that 

575
00:27:12,240 --> 00:27:14,720
specialized in those cases when 
I was in law school, and I saw 

576
00:27:14,720 --> 00:27:17,320
how complicated they can get. 
What are some of the trickiest 

577
00:27:17,320 --> 00:27:19,120
things about causation in those 
cases? 

578
00:27:19,360 --> 00:27:22,400
Well, the main thing to remember
is that in workers compensation 

579
00:27:22,400 --> 00:27:25,920
cases, it's not about proving 
that the employer did something 

580
00:27:25,920 --> 00:27:28,960
wrong. 
The big question is whether the 

581
00:27:28,960 --> 00:27:31,680
employee got hurt while doing 
their job. 

582
00:27:32,000 --> 00:27:34,760
Was it work related? 
So like if I'm at work in an 

583
00:27:34,760 --> 00:27:38,120
office and I slip on a wet floor
and break my ankle, they'd 

584
00:27:38,120 --> 00:27:41,400
usually assume that happened 
because I was at work, even if 

585
00:27:41,400 --> 00:27:44,160
no one was specifically to blame
for the wet floor. 

586
00:27:44,160 --> 00:27:46,400
Yeah, that's typically how it 
works. 

587
00:27:46,480 --> 00:27:49,120
But of course there are 
exceptions, like if the employee

588
00:27:49,120 --> 00:27:52,080
was drunk or high, or if they 
intentionally did something 

589
00:27:52,080 --> 00:27:55,200
wrong, or if they got hurt doing
something totally unrelated to 

590
00:27:55,200 --> 00:27:57,960
their job, then they might not 
get workers comp. 

591
00:27:58,320 --> 00:28:00,480
Got it. 
So there's this assumption that 

592
00:28:00,480 --> 00:28:03,680
injuries at work are work 
related, unless you could prove 

593
00:28:03,680 --> 00:28:04,760
otherwise. 
Right. 

594
00:28:04,920 --> 00:28:06,960
But it can be way more 
complicated when you're talking 

595
00:28:06,960 --> 00:28:09,440
about those occupational 
diseases that people develop 

596
00:28:09,440 --> 00:28:12,800
over time, like from being 
exposed to dangerous substances.

597
00:28:12,800 --> 00:28:15,600
Oh right, like a construction 
worker who gets lung cancer 

598
00:28:15,600 --> 00:28:18,680
after years of breathing in 
asbestos on the job. 

599
00:28:18,680 --> 00:28:21,120
Exactly. 
In those cases you have to prove

600
00:28:21,120 --> 00:28:24,320
that they got sick because of 
the exposure at work and not 

601
00:28:24,320 --> 00:28:26,520
because of something else like 
smoking. 

602
00:28:27,320 --> 00:28:31,000
These cases often involve a lot 
of medical experts, specialists 

603
00:28:31,000 --> 00:28:34,800
in workplace safety, and tons of
analysis of the work environment

604
00:28:34,800 --> 00:28:37,480
and safety procedures. 
It sounds like a very detailed 

605
00:28:37,480 --> 00:28:41,000
process of piercing together 
evidence and making a strong 

606
00:28:41,000 --> 00:28:44,560
case to connect the dock between
what happened at work and the 

607
00:28:44,560 --> 00:28:46,960
illness. 
It is, and it's crucial to have 

608
00:28:46,960 --> 00:28:50,800
thorough investigations, good 
record keeping and those expert 

609
00:28:50,800 --> 00:28:53,240
opinions to back everything up. 
Well, I think we've covered a 

610
00:28:53,240 --> 00:28:55,360
ton today. 
We've looked at causation in so 

611
00:28:55,360 --> 00:28:58,240
many different legal situations.
It's definitely one of those 

612
00:28:58,240 --> 00:29:00,400
fundamental legal concepts that 
pops up everywhere. 

613
00:29:00,480 --> 00:29:03,040
It really is, and as we've 
talked about, it's often tied to

614
00:29:03,040 --> 00:29:05,880
these really complicated 
situations, scientific evidence,

615
00:29:06,160 --> 00:29:08,200
and how society's values are 
changing. 

616
00:29:08,280 --> 00:29:10,640
It shows that being a good 
lawyer isn't just about 

617
00:29:10,640 --> 00:29:13,560
memorizing a bunch of rules. 
It's about being able to think 

618
00:29:13,560 --> 00:29:17,680
critically, analyze situations 
carefully, and understand how 

619
00:29:17,680 --> 00:29:21,640
those legal principles apply in 
messy, real world situations. 

620
00:29:21,840 --> 00:29:24,600
Couldn't agree more. 
And as you all continue your 

621
00:29:24,600 --> 00:29:28,200
legal journey, it's so important
to keep asking questions, 

622
00:29:28,520 --> 00:29:31,360
challenging what you think you 
know, and working to make the 

623
00:29:31,360 --> 00:29:34,040
legal system and the world a 
better place. 

624
00:29:34,400 --> 00:29:35,720
Couldn't have said it better 
myself. 

625
00:29:36,880 --> 00:29:38,520
That's a great way to wrap 
things up. 

626
00:29:38,840 --> 00:29:42,040
We've really gone deep on 
causation today, looking at all 

627
00:29:42,040 --> 00:29:45,360
its twists and turns, how 
complex it can be, and how it 

628
00:29:45,360 --> 00:29:48,280
shapes the legal world. 
I hope this deep dive has given 

629
00:29:48,280 --> 00:29:51,200
you a good understanding of 
these really important ideas and

630
00:29:51,200 --> 00:29:53,480
that it's made you want to keep 
learning about the law. 

631
00:29:53,640 --> 00:29:55,560
Absolutely. 
This is just the beginning. 

632
00:29:55,560 --> 00:29:58,080
So keep learning, keep 
exploring, and keep pushing 

633
00:29:58,080 --> 00:29:59,920
yourselves to be the best 
lawyers you can be. 

634
00:30:00,800 --> 00:30:03,520
Thanks for joining us for this
