CROSS EXAMINING THE DEFENSE EXPERT
By Paul R. Kiesel, Esq.
The approach to cross examining the defense medical expert varies on a case-to-case
basis. Although there are no specific, articulable standards to be rigidly applied in all
cases, this article will suggest some areas of focus which may be appropriate to your case
and which may spark you to consider other new approaches of your own. Perhaps the
only (but foremost) rule to follow is to be adequately prepared for your examination of
the expert, whether for purposes of deposition or trial. My own practice is not to cross-
examine the medical expert in deposition but, rather, to simply elicit the opinions and
conclusions reached by the doctor, to the extent that they are not set forth in any prior
defense medical examination report.
Qualifications
Many lawyers simply accept the proposition that an expert identified by the defense and
prepared to testify on his/her behalf is qualified. Frequently, counsel fails to adequately
study the medical expert's curriculum vitae. It is most important carefully scrutinize the
curriculum vitae both for appropriate foundation for the opinions the doctor is attempting
to offer as well as the experience upon which the doctor relies to justify the his/her
opinions and conclusions.
Certainly, at the time of trial, prior to cross-examination, the curriculum vitae should be
carefully examined. The curriculum vitae may reveal that the expert has been essentially
out of the actual practice of medicine for some years and has chosen to substitute forensic
medicine in its stead. Forensic medicine is typically viewed as the consultation with
attorneys coupled with medical review and perhaps one physical examination of plaintiff.
It is important to know what percentage of time the medical expert devotes to forensic
medicine as opposed to actual treatment. One of the most fertile areas for investigation
into a medical expert's qualifications is a review of the expert's published articles or
presentations. I cannot emphasize enough how important it is to identify all articles
written by the defense medical expert and to review these prior to cross- examining the
expert at the time of trial. On more than half a dozen occasions, a review of the medical
examiner's published writings has unearthed statements and opinions inconsistent with
the defense position in the case at bar.
To the extent that none of the articles written by the expert are relevant to the issues
being litigated, the doctor's lack of expertise in the subject matter of the trial should be
emphasized. This fact, considered in conjunction with the considerable expertise of
plaintiff's expert in the area disputed at trial, provides an excellent basis for discrediting
the defense expert's opinions.
Sometimes, doctors include personal information which, while having no bearing on the
testimony offered, may provide another interesting area of inquiry. Do not be afraid to
explore the curriculum vitae for any potential pressure point which could be applied
during cross-examination.
Prior Trial and Deposition Testimony
At the defense expert's deposition it is important to inquire into the witness' prior
activities as an expert witness. The inquiry should focus on the following issues:
* The number of forensic cases, i.e., non-treating cases that the witness is involved
in each year.
* The number of times the witness has testified as an expert as a treating physician
in the prior year.
* The percent allocation between work for plaintiffs and work for defense.
* The charges on the particular matter at issue and the breakdown of those charges.
* The average charge in a litigation case (using broad estimates, if necessary).
* The total number of litigation cases worked on per year.
* The number of cases reviewed for this particular defense firm.
* The number of cases reviewed for this particular insurance carrier.
A Notice of Taking Deposition of the defendant expert might be helpful in acquiring
some of this information pre-deposition.
Obtaining prior deposition and, whenever possible, trial testimony of the expert witness is
essential in preparing to cross-examine the witness. I recommend that you use the jury
reporting services to find the number of times a particular witness has testified at trial and
that you contact the respective parties to obtain transcripts of the witness' prior testimony.
There is a gold mine of information to be discovered from the prior testimony of an
expert witness. Therefore, you should always attempt to obtain any available transcripts
of prior testimony for use in your case. I recommend that you refrain from cross-
examination of the expert witness at the time of the deposition, if adverse information
exists in prior testimony, and, instead, save this bullet for trial.
Additionally, if the expert has his doctoral degree, you should inquire as to the nature of
the doctoral thesis. In one case, an expert witness wrote a thesis which contradicted most
of the important opinions and conclusions he offered for the defense.
Developing Background Information
Sometimes background information can be developed from sources apart from the
deposition inquiry in the particular case. For example, some organizations and lawyers
keep banks of past deposition transcripts of certain witnesses whose names appear
frequently in lawsuits. While those depositions may not be on point for a particular
medical issue, they may provide background about the witness which may be useful at
the time of trial and which may impeach the witness' testimony.
Percentage of Work as Expert vs. Treating Physician
Perhaps the greatest area of vulnerability for a forensic expert is the degree to which
his/her practice is devoted to expert testimony rather than medical treatment. Often, the
non-treating physician is viewed as a "hired gun" when juxtaposed with plaintiff's actual
treating physician. Sometimes the information concerning the extent to which the expert
performs forensic work can be determined from the deposition, but often the true
information can only be obtained through colleagues or former colleagues who have
familiarity with the doctor's practice. Questioning the doctor as to how frequently s/he is
in surgery and how many hours per week are spent in treating patients can be helpful in
developing an accurate breakdown of the doctor's practice. If enough estimates are
obtained during depositions concerning hours spent on forensic consultation and hours
spent treating patients, the total number of hours may be such as to make it appear
impossible for the doctor to do anything but work.
Conduct of the Examination
Some lawyers seek to reduce the defense medical examination to video tape or audio tape
to preserve the information for use at trial. This strategy can cut both ways, however, and
the decision whether to use it should be given careful consideration. Nevertheless, it is
very important to require the doctor to accurately describe how long it took to perform
the defense medical examination. Sometimes, the time spent on the examination is so
short that the jury is shocked by the time and the charges claimed by the defense medical
examiner.
The defense doctor will frequently characterize the plaintiff's complaints as "subjective."
The doctor will have to admit, however, that many of his or her own determinations and
evaluations (and even some of the testing) depend upon the doctor's subjectivity. For
example, the examiner's testing of muscle tone, guarding, spasms, and straight leg raising
all contain elements of subjectivity which the doctor interposes into the examination. In
the event that the doctor is biased against the patient, his/her subjective views may be
biased as well.
Blood tests, x-rays, MRI scans and the like are usually considered to be objective tests.
The validity of such tests, however, can sometimes be questionable and may depend upon
the fairness of the doctor in documenting the test. Certain organizations now exist which
will send representatives to the defense medical examination to record the details of such
testing and make suggestions as to how the doctor can be cross-examined.
Medical History
During most examinations, the physician will inquire extensively about plaintiff's history.
By doing that, the defense doctor has recognized what all doctors have recognized, i.e.,
that history is important in determining the cause of certain injuries. Sometimes, history
is the most powerful weapon in the plaintiff's arsenal to prove that this particular accident
caused plaintiff's injury. Obviously, if plaintiff had no back problem before the
automobile accident, and plaintiff has a herniated disc which can be identified on a CT
scan after the accident, then the mere historical sequence of events will prove causation
by a preponderance of the evidence.
Frequently, the defense doctor's own recordation of the history in his or her own report
will be sufficient for cross-examination on the issue of history. Beyond that, the medical
records the defense doctor will have reviewed may also provide helpful post- accident
history concerning the injury and the scarcity or complete absence of similar history
concerning the relevant area of the body prior to the accident.
It is important, however, to be sure that you carefully review all of the medical histories
recorded by plaintiff's treating physicians before trial to ensure that they are consistent
with the history the plaintiff has given you and other facts of the case. To the extent there
is information which is inconsistent with the histories reported by plaintiff's treating
physicians, it is important to determine the bases for such differences in order to be
prepared explain any inconsistencies and rebut anticipated impeachment.
Tests Not Performed
Sometimes, defense doctors perform only certain tests but decline to administer others. It
may be helpful to explore with the doctor in cross-examination the variety of tests
available to the doctor which were not performed. It is important to discuss with your
treating physicians the tests which they performed, determine the purposes of these tests
and then compare them with the tests administered by the defense medical examiner. To
the extent that other tests were available and the defense doctor chose not to conduct
them, the defense examiner's opinions and conclusions are vulnerable to attack on this
basis.
Preparation, Preparation and More Preparation
Preparation is the key to effective cross-examination of a defense medical examiner. The
jury is aware that this expert is a paid consultant - not a treating physician - and, perhaps,
that s/he is being very well paid for the services provided. The credibility of such
witnesses and the foundation for their opinions and conclusions are very vulnerable to
attack, but only to the extent plaintiff's counsel is willing to dig the background,
education and prior experience of the particular witness, and thereby adequately prepare
to conduct an effective cross-examination.
