Ethics of Expert Witness from Lawyer's Perspective

HIDE
PrevNext

0:00

Hi everybody.

0:02

I wanna take some time, uh, to follow up

0:04

with Dave's talk on, uh, his perspectives in terms

0:08

of being an expert witness,

0:10

and give you some perspectives about

0:12

how lawyers look at expert witnesses

0:14

and what we expect from you and you can expect from us.

0:17

Um, and especially, um, obviously

0:21

as I'm a plaintiff's medical malpractice attorney, uh,

0:24

perspective from that side as well.

0:27

So, in terms of how we look at your

0:32

responsibilities as an expert witness, we're really looking

0:36

for someone who's going to present well to a jury,

0:38

as Dave I know, talked about,

0:40

but I want you to be confident, personal, personable,

0:45

and, you know, have, have you be somebody

0:48

that the jury can relate with as you're talking to them.

0:52

You also, however, have to be able to have the ability

0:56

to make firm decisions and to stick by them.

1:00

Now, if there's evidence presented, obviously,

1:03

which causes your opinion to change, that's fine.

1:06

But when you've, you know, by the time we've gotten

1:08

to deposition and particularly to trial,

1:11

you should have had all of the information.

1:13

You've reviewed it, we know what your opinions are,

1:16

and then we expect you to stick by those opinions.

1:19

Um, in terms of being an expert witness.

1:22

And Dave talked about what the a CR says in terms

1:25

of an obligation.

1:27

Um, but I find that there are certain individuals

1:30

who are good at doing this and want to do this

1:33

and others not so much, and that's fine as well.

1:36

Um, but if you are going to do this, uh,

1:40

you've gotta be willing to involve yourself in what is adv,

1:44

obviously an adversarial process,

1:46

and know that going in some people are, are suited to that

1:51

and some people aren't.

1:52

I work with a lot of, uh, physicians from across the country

1:55

and every specialty that you can imagine,

1:58

and, um, a lot of 'em just really enjoy doing it.

2:01

I will say that the one thing I am told all the time

2:06

by my expert witnesses is that they do it in large part.

2:10

They enjoy the process,

2:11

but they tell me that they learn so much from the process.

2:16

Uh, so there's that. Uh, the other thing is you need

2:19

to be able to really embrace your role as a teacher,

2:23

as an educator, uh, not only for the attorney

2:25

or attorneys that you're working with, but for the jury.

2:29

Um, your job is going to be in the courtroom to partly, uh,

2:34

explain to the jury the, the setup for what's going on here.

2:39

And we have to do that largely through you

2:42

because I can't testify.

2:43

I can ask you the questions,

2:45

but I'm going to need you to turn to the jury, look at them,

2:48

and be willing to explain the process.

2:50

And of course, we help you with that.

2:51

We give you the props and that type of thing,

2:53

but that's also a role that's very integral

2:56

to this entire system.

2:58

Um, and then finally, one of the things

3:00

that you've really got to be able

3:02

to do when you're on the stand is defend your opinions.

3:06

And by the time, again, we get to deposition

3:08

and to trial, you should be well prepared for that.

3:11

You know what's coming at you.

3:13

Your attorney hopefully has worked with you

3:15

and told you the questions

3:16

that the opposing counsel is going to ask, as well

3:20

as the questions that they're going

3:21

to ask you to set this up.

3:23

So that's, um, that's really an important piece of this

3:28

and hopefully you've been well prepped, uh, you know,

3:30

to get you to that point, um, moving forward,

3:35

as Dave talked about, I'm not gonna, uh,

3:37

spend too much time on this,

3:38

but you should be willing to work for both sides.

3:41

It's important for your objectivity and for your bias.

3:45

Um, I think, as I mentioned briefly, I will not hire someone

3:48

who only does plaintiff's work even though I'm a plaintiff's

3:51

attorney, because they're, they're just not credible.

3:55

They're just not credible. And I do find

3:57

that far more often on the defense side.

4:00

So a lot of lawyers that put witnesses,

4:03

expert witnesses on the stand that only do defense work,

4:06

quite frankly, I think

4:07

that they're an easy mark in that regard.

4:08

So just something to consider, it is your job

4:13

as an expert witness to objectively review the evidence

4:18

and form opinions based on the facts.

4:21

You're not looking at the case and looking at the outcome

4:24

and saying, gee, you know, the mom of three kids died,

4:28

and the so therefore I want no, your, your job is

4:32

to objectively look at the defined area

4:34

that you've been tasked with

4:37

and form opinions that you can, that are solid

4:40

and that you can back up.

4:42

Um, having said that, and we did talk about that somewhat

4:45

and I'll talk about that a little bit more in the,

4:47

in the next talk, is that your opinions as you do this work,

4:52

do not have, they can be,

4:54

but they do not have to be to a hundred percent.

4:57

The standard is to a reasonable degree

4:59

of medical probability, which is just more likely than not,

5:03

which means it's a pretty solid opinion.

5:05

You've looked at everything

5:06

and it is your, this is your opinion.

5:10

Um, in order to do that,

5:12

and you will be tested on this, you do have

5:14

to have a solid current knowledge of the subject matter.

5:19

And Dave talked about the fact that you have

5:22

to go back sometimes in time and look what was available.

5:26

Um, but the other thing that can happen is you do have

5:30

to have a current knowledge

5:31

because that gets into the area of causation, right?

5:34

If there's new evidence that's come out that something did

5:38

or didn't cause it, you have to be aware of that.

5:40

So a solid understanding of the medicine at the time

5:45

of the event as well as currently.

5:47

Um, and again, the, uh, you have to be able

5:52

to articulate and they will ask you at some point, probably

5:56

during your deposition, doctor,

5:58

what is the standard of care here?

6:00

And they're trying to trip you up.

6:01

So you want to be able, you wanna have that memorized

6:05

and know what it is going forward.

6:07

It's what a, a physician, uh, you know,

6:09

a reasonable physician would do under the same

6:12

or similar circumstances.

6:13

And that's, um, you know, you can spout that off.

6:16

Then you move forward to the next one.

6:18

They're done testing you on that. Um, hey,

6:21

Um, can I interject one thing about your

6:23

bullet number three?

6:25

And that is that a lot of times the expert witness

6:31

will be given the facts from the lawyer

6:34

that is hiring them.

6:37

And I, I have been fooled by a biased view

6:42

of the facts that have been given to me by the lawyer

6:46

as opposed to going into the medical record

6:49

and deriving the facts myself.

6:53

Sometimes the lawyers will overlook something intentionally

6:57

or unintentionally that may change my opinion

7:00

based on my medical knowledge,

7:02

not necessarily learn the medical knowledge.

7:04

So don't, what I would say is one of the pitfalls

7:07

of being a medical expert is do not trust that the

7:12

review or summary of the case given to you by the lawyer,

7:16

uh, includes all of the information that you need

7:19

to provide your opinions.

7:23

So, uh, following up on that, I would say that

7:25

that's a great point, and that is that does happen.

7:29

Um, but let me tell you what I tell my experts if

7:33

that situation arises, you know, I give them everything

7:36

that they believe that they will need to review

7:39

and form their opinions about.

7:41

I tell them, if you feel

7:43

that there is something else out there that

7:47

that should be there that you would like to review,

7:50

if we can get it, please let me know.

7:51

We will absolutely get it for you.

7:54

But another thing that um, happens,

7:57

and it happens frequently in these cases, is

8:00

that I am sharing information with an expert based on

8:04

working with other experts, my knowledge of the plaintiff,

8:07

my knowledge of the area.

8:09

And I will say to them, you need to have this information.

8:14

I don't have a written document for you.

8:16

I can tell you the plaintiff is having

8:19

these signed symptoms.

8:20

This is what's going on with the plaintiff.

8:22

And I can, I can give you, you know,

8:25

this additional information, addit information, um,

8:28

but it may not be in what you would consider

8:30

to be like a medical record form.

8:31

And here's what I tell the, the, uh, expert is

8:35

that if you are asked about that

8:37

or if you are challenged on that, you absolutely respond

8:42

by saying, that information was

8:44

provided to me by plaintiff's counsel, right?

8:48

That, um, and I have relied on that.

8:51

If it's not accurate

8:52

or you've got additional information for me to look at,

8:55

please let me know and I'll be happy

8:57

to tell you if it alters my opinions.

8:59

But I do that because sometimes we don't have

9:01

that additional information yet I'm able

9:04

to back it up in a non-medical record form.

9:07

So I think that that's important for you to do

9:09

because one of the things we'll talk about is,

9:12

and as Dave mentioned, your testimony follows you.

9:17

And I am very careful with my experts to

9:20

just stringently guard their credibility

9:24

and their ability to testify going forward in a way

9:28

that's not going to get them impeached.

9:30

And any attorney that you work

9:32

with on either side should be willing to do

9:35

that and do that.

9:36

So that's my two son's worth on that.
