The good folks at
IMS ExpertServices have published an interesting short article highlighting the increasingly difficult technical
issues being brought before courts in intellectual property (IP) cases. Attorney
who holds degrees in both law and journalism, tells here about a recent court ruling that places severe restrictions
on the ability of an expert witness to cite and admit as evidence material based on the work of another non-testifying
expert witness. Known in the legal realm as 'bootstrapping,' the practice has greatly burdened efforts required
to rebut massive volumes of opinions admitted as evidence based solely on the endorsement of an expert who is
physically present and testifying in the courtroom. This strategy, used extensively in patent cases, is especially
advantageous to well-funded legal defense teams who can afford to spend lavishly on material to overwhelm an opponent.
Mr. Thompson's story reports on a judge's ruling in a specific case in New Jersey that is being promoted as a
precedent for, in many people's hopes, nationwide application. Successful adoption means job security for experts
since they will need to be hired to appear in court and present their own research.

Ryan Thompson, Esq.
Ryan's experience in the legal industry coupled with his work in journalism brings a unique voice to this
exclusive BullsEye content. He is an assistant general counsel and writing professor at Niagara University.
He has a degree in journalism from the University of Colorado and a law degree from Brooklyn Law School. Admitted
to the New York bar in 2005, he previously worked at a Fifth Avenue law firm where he specialized in in-court
The expert testified that another expert said that, according to this other expert, who examined the report
of this other expert, according to this expert who indicated that this other expert's report said this other expert
said so. Say what?
Perhaps this exaggerated and silly scenario is a bit extreme. However, this expert-opinion "bootstrapping,"
as the courts call it, has become problematic in civil cases of all sorts. One expert properly testifies as to
his or her opinion but then also testifies as to whether his or her opinion is consistent with another non-testifying
Rule 703 of the Federal Rules of Evidence, and the state counterpart rule in many states, specifically allows
experts to base their opinions on inadmissible evidence, like hearsay. However, there is a significant difference
between basing an opinion on inadmissible evidence and testifying to it directly. If the offering party
seeks to show that its expert's opinion is valid because (among other reasons) it is consistent with other non-testifying
experts' opinions, this represents quintessential, inadmissible hearsay evidence. It is a back-door hearsay
loophole that attorneys have been using for years to present otherwise inadmissible evidence to a judge or jury
and at least one state appellate court has had enough.
The Ruiz Ruling's Reach
Several weeks ago, the New Jersey Appellate Division ruled in a precedent-setting decision that bootstrapping
expert opinions of non-testifying experts will be prohibited. No longer can attorneys ask their experts under
direct examination whether their opinions are consistent with a non-testifying expert's report, nor can attorneys
ask under cross-examination whether an opposing expert's opinion is inconsistent with a non-testifying expert's
While the recent ruling may only impact expert witnesses in New Jersey for the time being, the "bootstrapping"
prohibition is likely to gain momentum with other state and federal judiciaries – as American courts have long
supported parties' rights to cross-examine witnesses against them and for juries to see the same.
Will a banking expert be permitted to testify regarding previously prepared financial reports by another expert?
Will a patent expert be allowed to reference reports prepared by computer programmers prior to trial?
Ultimately, the ruling in James v. Ruiz may mean increased costs for litigants who need to introduce the reports
of various experts. Now, each expert must be called upon to testify in court.
Attorney Chad Moore, who represented the defendant in Ruiz, said that though the ruling applies to all parties,
it will likely increase costs for plaintiffs' attorneys, whom he says employ the bootstrapping tactics more than
defense attorneys do, especially in personal injury actions.
"You'd be defending yourself against two or three expert opinions through one doctor," Moore told the New Jersey
Law Journal. "This case puts an end to that practice."
Moore called the Ruiz ruling a "big win for the defense bar." Though, the appellate court panel made it clear
that their decision will reach far beyond the realms of personal injury litigation.
Cutting the Bootstraps
"We hold that a civil trial attorney may not pose such consistency/inconsistency questions to a testifying
expert, where the manifest purpose of those questions is to have the jury consider for their truth the absent
expert's hearsay opinions about complex and disputed matters," the appellate court wrote in its March 25 decision
in Ruiz. "Even where the questioner's claimed purpose is solely restricted to impeaching the credibility of an
adversary's testifying expert, spotlighting that opposing expert's disregard or rejection of the non-testifying
expert's complex and disputed opinions, we hold that such questioning ordinarily should be disallowed . . . ."
There are two major points to note in the above holding. (1) The court states that this prohibition is
only applicable to "complex and disputed" matters; and, (2) the court states that this decision is also applicable
when attorneys claim that they are questioning the expert, not for the truth of the non-testifying expert's opinions,
but simply to impeach the testifying expert. The court carefully addresses both above
provide for hearsay exceptions or exclusions in both the state and federal courts.
The first addresses the business record hearsay exception – Rule 803(c)(6) of the New Jersey Rules of Evidence
and Rule 803(6) of the Federal Rules of Evidence – that allows for hearsay evidence to be excepted and admitted
into evidence when it is a record of a regularly conducted activity and that there is no indication of lack of
Here, the court holds that the business record hearsay exception would not apply to these situations of "complex
and disputed" matters.
The second point of note that the court addresses has to do with the hearsay exclusion for statements made,
not for the truth of what is being said, but instead only for purposes of impeaching the witness's credibility.
The appellate court makes it clear that attorneys alleging such motives will not be permitted to sneak in such
bootstrapped statements of non-testifying experts.
"Lastly, we hold that the closing arguments of counsel should adhere to these restrictions, so as to prevent
the jury from speculating about or misusing an absent expert's complex and disputed findings," New Jersey Appellate
Division Judge Jack Sabatino wrote on behalf of the three-judge panel. Thus, the hearsay loophole similarly cannot
be used in summations either.
A Daubert Paradox?
Does this decision contradict the Daubert standard for admissibility of expert testimony?
Novice legal observers may initially think so, as the Daubert standard requires the court to determine, in
part, whether the expert's technique or theory can be or has been tested, whether the technique or theory has
been subject to peer review and publication, and also whether the technique or theory has been generally accepted
in the scientific community.
Well, how then can another non-testifying expert's report not be admissible to be used to compare the credibility
of the testifying expert?
The answer is simple: The Daubert standard is applied during pretrial hearings by a judge with no jury. The
test is used to determine whether or not an expert witness's testimony will be admissible at a later trial, not
used at the trial itself.
The Ruiz ruling is all about what is admissible at the actual trial, and what testimony and evidence will be
permitted to be offered to the jury's eyes and ears.
"The admissibility problem here stemmed from plaintiff's effort, in effect, to use the hearsay opinion of [the
non-testifying expert] substantively as a ‘tie breaker,' providing the jury with a third opinion on the hotly
disputed subject," the Ruiz court explained. "The [non-testifying expert's] opinion was not subjected to cross-examination
and the jury was not afforded a chance to observe his testimonial demeanor. Instead, the substance of his opinion
was being slipped in through the proverbial ‘back door.'"
Closing the Back Door
Indeed, the court has decided it is time to shut the back door. Litigants and lawyers will be forced out front,
and admittance through the main expert-witness entrance may prove to be much more costly.
As the Princeton-based environmental law firm Lieberman & Blecher, P.C. posted on its website the day after
the Ruiz decision was issued, "The significance of this case should not be understated. The exclusion of
non-testifying expert opinions in such contexts has the potential to affect a wide variety of cases involving
expert witnesses. Counsel needs to take great care to call as a witness any expert whose opinion will be introduced
for its substance, and possibly even for impeachment purposes."
Ultimately, the Ruiz case could mean more experts must be retained.
Do you think the Ruiz precedent will soon expand to state and federal jurisdictions, precluding "back door,
bootstrapping" of expert opinions in courts across the nation?
