Opinion

Gants, J.

On March 14, 2003, after three weeks of trial, the juiy returned its verdict finding that the respondent Alden Baker (“Baker”) was not a sexually dangerous person (“SDP”) as defined in G.L.c. 123A, §1. While this Court addressed a host of difficult legal issues during the course of that trial, there were two issues that merit the preparation of a post-trial memorandum of law because of the strong likelihood that these issues will emerge again in future SDP trials.

1. The Definition of a Reasonable Degree of Professional Certainty

At trial, the Commonwealth called only two witnesses, Qualified Examiners Niklos Tomich and Stephen DeLisi. Both offered opinions “to a reasonable degree of professional certainly” that Baker suffered from a mental abnormality or personality disorder, and that he was likely to engage in sexual offenses if not confined to a secure facility. Before they testified, this Court conducted a voir dire to learn how they defined the term “to a reasonable degree of professional certainty” and allowed inquiry at trial as to how they defined this term. Both testified, in essence, that “a reasonable degree of professional certainty” was the degree of certainty that they relied upon in their professional life in making clinical judgments. Neither explained what level of certainty they required before they made clinical judgments, or whether this level of certainty was the same as to all patients and all clinical contexts. Dr. DeLisi also offered an alternative, quite different definition — the degree of certainty sufficient to allow members of the profession to reach the same conclusion. Dr. DeLisi emphasized that this was not the level of certainty that necessarily meant that members of the profession “would” reach the same conclusion; it was simply that quantum of certainty needed so that members of the profession “could” reach the same conclusion.1

Both Drs. Tomich and DeLisi admitted that “a reasonable degree of professional certainty” did not mean “beyond a reasonable doubt.”2 Indeed, both testified that they could not opine beyond a reasonable doubt that Baker either suffered from a mental abnormality or personality disorder, or that he was likely to engage in sexual offenses if not confined to a secure facility.

The Commonwealth vigorously objected to this Court allowing inquiry as to whether the opinions the qualified examiners had “to a reasonable degree of professional certainty” meant that they held these opinions “beyond a reasonable doubt,” contending that it “usurped” the role of the jury. This Court ruled that this inquiry did not in any way “usurp” the role of the juiy but rather protected the jury from the misunderstanding and confusion that can lead to a miscarriage of justice. While the Court explained the basis for this ruling on the record at trial, it is useful to articulate it again in writing.

When a medical expert offers an opinion in a medical malpractice case that the defendant doctor, “to a reasonable degree of medical certainty,” breached the standard of care of the average doctor in his speciality, the juiy reasonably understands that the expert holds his opinion, at least, by a preponderance of the evidence. As a result, the juiy reasonably understands that the medical expert, based on what he knows about medicine and has learned from the records he has reviewed, has found by a preponderance of the evidence that the defendant doctor breached the standard of care. Consequently, the plaintiffs attorney does not invite confusion or misunderstanding when he argues to the juiy that they should find the defendant doctor negligent based on the opinion of that medical expert. Nor does anyone conclude that the role of the juiy has been “usurped” by being allowed to hear such an opinion.

In an SDP case, however, the burden on the Commonwealth is not a fair preponderance of the evidence, but proof beyond a reasonable doubt. When a psychologist offers an opinion that a respondent is an SDP “to a reasonable degree of professional certainty” and does [102]*102not carefully define this term, the jury reasonably will understand that the expert holds his opinion to a degree of certainty that would permit the jury, if it were to find him credible and rely on his testimony, to conclude that the respondent is an SDP. The jury will come to this understanding based both on context and language. The context is that the Assistant District Attorney has essentially told them in his opening statement (and will again tell them in his closing argument) that the qualified examiners have concluded that the respondent is an SDP and that they should be persuaded by these expert opinions to reach the same conclusion. As to language, the phrase the expert will use to describe the strength of his opinion is a “reasonable degree of professional certainty.” The jury will be told by the Court, as part of its Webster instruction, that proof beyond a reasonable doubt means that the evidence must convince them that the respondent is a sexually dangerous person “to a reasonable and moral certainty; a certainty that convinces your understanding and satisfies your reason and judgment as jurors who are sworn to act conscientiously on the evidence.” Unless a linguist is among the jurors, the jury is not likely to recognize that a “reasonable degree of professional certainty” may constitute a far lower degree of certainty than “a reasonable and moral certainly.”

Indeed, if the qualified examiners’ understanding of the term — "a reasonable degree of professional certainty" — were not explored in the testimony, the jury almost certainly would have assumed that the qualified examiners, based on the information they had reviewed, had found the respondent to be sexually dangerous beyond a reasonable doubt. Here, that assumption would have been wrong. The fact of the matter is that both the qualified examiners, had they been jurors and required to determine sexual dangerousness based solely on the information known to them, would have been required to find that Baker was not an SDP, because both could not conclude that he was sexually dangerous beyond a reasonable doubt. In other words, both the experts the Commonwealth put on the stand to convince the jury that it should find Baker to be an SDP beyond a reasonable doubt did not find Baker to be an SDP beyond a reasonable doubt.3

Justice demands that a jury be permitted to understand what an expert means when he offers an opinion “to a reasonable degree of professional certainty,” and not be left to assume its meaning, especially when the jury’s assumption is likely to be erroneous. This does not “usurp” the jury’s role as factfinder. By hearing this testimony, a jury in an SDP case, like a jury in a medical malpractice case, is not delegating to the expert its responsibility to render a verdict. Rather, allowing this testimony respects the jury’s need to find the truth, and not be misled or confused by the jargon used in the trial.

Indeed, allowing this testimony amounts to little more than allowing inquiry into the expert’s definition of a term of art the expert has used in his testimony. When an expert answers, “yes” to the question, “Do you have an opinion to a reasonable degree of professional certainty?,” the expert is adopting the use of that term — a reasonable degree of professional certainty — as his own. It is certainly permissible to ask the expert what he understands that term to mean.
