In United States v. Llera Plaza, 188 F. Supp. 2d 549 (E.D. Pa. 2002), a federal district initially limited expert opinion testimony on fingerprint identifications because the government was unable to show that such identifications were sufficiently valid and reliable under Federal Rule of Evidence 702. Then, the court withdrew the opinion. This article reproduces an exchange of notes on the initial opinion submitted by five law professors.

George Bernard Shaw famously said that all professions are conspiracies against the laity. Less famously, less elegantly, but at least as accurately, Andrew Abbott argued that professions are conspiracies against each other. Professions compete for authority to do work and for authority over work. The umpire in these skirmishes and sieges is the government, for the state holds the gift of monopoly and the power to regulate it. In Abbott's terms, "bioethics" is contesting medicine's power to influence the way doctors treat patients. If it follows the classic pattern, bioethics will solicit work and authority by recruiting government's power. A …
Detection Of Deception: The Case Of Handwriting Expertise, Samuel R. Gross
Detection Of Deception: The Case Of Handwriting Expertise, Samuel R. Gross
Articles
The basic method of handwriting identification is the same now as it was in Twelfth Night: to compare the questioned writing with other writings by the supposed writer. This can be done from memory if (like Malvolio) one is already familiar with the claimed author's handwriting, or by examining the questioned document together with known samples. It's a simple, obvious task. Any person-certainly any literate person--can have a go at it. The claim by handwriting experts, now and in the past, is equally simple: We can do it better.

On its face, Daubert v. Merrell Dow Pharmaceuticals was about as easy a case as the Supreme Court gets. The plaintiffs claimed that their birth defects were caused by the anti-nausea drug Bendectin, which their mothers had used during their gestation. In response to a motion for summary judgment by the defendant, the plaintiffs presented affidavits of eight expert witnesses who offered their opinions - based on a variety of studies - that Bendectin was indeed the culprit. The federal district court that heard the motion granted summary judgment to the defendant, and the Ninth Circuit affirmed. Both lower courts …

It seems that the use of expert witnesses in common law courts has always been troublesome. In his Treatise on the Law of Evidence, first published in 1848, Judge John Pitt Taylor describes several classes of witnesses whose testimony should be viewed with caution, including: enslaved people (which accounts for "the lamentable neglect of truth, which is evinced by most of the nations of India, by the subjects of the Czar, and by many of the peasantry in Ireland"); women (because they are more susceptible to "an innate vain love of the marvelous"); and "foreigners and others ... living out …
Opinions And Expert Testimony, John W. Reed
Opinions And Expert Testimony, John W. Reed
Book Chapters
Article VI of the Michigan Rules of Evidence contains the rules dealing with witnesses. Trials bring to mind testimonial evidence. There surely are other kinds of evidence, such as docmnents, guns, automobile tires, chemical substances, and the like. But most evidence comes from the mouths of witnesses, and even demonstrative evidence usually is admitted only after a witness has taken the stand and testified to foundation facts. So it is important and appropriate that we turn to the provisions of the rules that deal with qualifications and credibility of witnesses. I would like to direct your attention to MRE 601 …

Witness--Competency Of An Allopathic Expert In The Field Of Homeopathy--Opinion On Very Fact The Jury Must Determine, Victor H. Lane
Articles
Van Sickle v. Doolittle, (Ia., 1918), 169 N. W. 141, was an action for malpractice against a physician of the homeopathic school of medicine. Upon the trial, a physician of the allopathic school was called, and after testifying that he was unskilled in the science of homeopathy, was allowed to testify that the treatment shown to have been given to the patient by defendant, would produce no physiological effect, and that proper treatment required the giving of such medicines as would produce such effect. This was held error upon the ground that the defendant was called to treat the patient …
Examination Of The Medical Expert, Harry B. Hutchins
Examination Of The Medical Expert, Harry B. Hutchins
Articles
The expert witness differs essentially from the ordinary witness in at least two particulars; first, in that the field of his testimony is outside the range of ordinary knowledge and experience; and, secondly, in that his testimony in the great majority of cases is in the form of opinions or conclusions that are deemed necessary for the proper guidance of the jury. It goes without saying that the 'lawyer who undertakes the examination of the expert should have such familiarity with the subject of inquiry as will enable him to develop it through the expert logically and clearly, but unfortunately …

The Physician As An Expert, Harry B. Hutchins
Articles
Expert evidence is evidence of a scientific or technical character in regard to a matter that is outside the domain of ordinary experience and knowledge. The evidence is usually in the form of opinions or conclusions based upon facts that for the purposes of an opinion are assumed to be true, although it may be in regard to scientific facts. The expert is one who has had special training or opportunities in a particular subject that the ordinary witness has not enjoyed, and who has thereby acquired certain habits of judgment.that render his explanations and opinions in the field of …
Compensation Of Experts, Henry W. Rogers
Compensation Of Experts, Henry W. Rogers
Articles
The law relating to the compensation of experts is somewhat unsettled, and the cases are not numerous in which the subject has been considered. This very fact, however, lends additional interest to the subject, and the question is one of great importance. In some of the States the law expressly provides that when a witness is summoned to testify as an expert he shall be entitled to extra compensation. Such a provision may be found in the laws of Iowa, of North Carolina, and of Rhode Island.
