Connecticut Supreme Court issues decision on informant experts

by

The Connecticut Supreme Court has decided that informant experts like myself are admissible when they can provide specialized information to jurors about informant unreliability, namely, information that jurors would not otherwise know based on common sense or from the popular culture or general media.  The Supreme Court upheld the exclusion of my testimony in this particular case, but noted that such testimony is not per se inadmissible, and it imagined other scenarios in which expert testimony might be admitted. The 2019 case, State v. Leniart, overturned this 2016 decision, in which the Connecticut Court of Appeals held that the trial judge made a mistake in preventing me from testifying before the jury.

I explain what the Leniart decision means in more detail in this piece for The Appeal: Why Juries Need Expert Help Assessing Jailhouse Informants.  In particular, I explain why jurors are unlikely to understand the full scope of informant practices, fabrications, and motivations to lie, and therefore would be helped by hearing expert testimony:

“Informants are highly motivated to give persuasive, believable testimony in exchange for their own freedom. They can also receive money, drugs, sex, food, and phone privileges when they cooperate with jail officials. Some scour the newspapers, pay other inmates for information, or get family members to pull court records so that they can come up with incriminating testimony against their cellmates. Some jurors may already know about these sorts of practices; many will not.”

Professor Robert Bloom on jailhouse informant expert testimony

by

Professor Robert Bloom is an expert on informants who has testified in numerous cases.  He has now authored this article,What Jurors Should Know about Informants: The Need for Expert Testimony, Mich. St. L. Rev. (forthcoming 2019).  Here is the abstract:  

  With the advent of DNA exonerations, the data would indicate that many individuals have been wrongly convicted. In looking at the causes of the exonerations, nearly 20% have involved testimony by accomplices and jailhouse informants. The questionable credibility of these individuals has long been recognized by courts and legislatures. Reforms in this area include, enhanced jury instructions, pre-trial credibility hearings, and corroboration before the testimony can be introduced.  

  This article argues the efficacy of expert testimony to further assist jurors in measuring the credibility of these witnesses. Although the use of experts has largely been disfavored by courts, there has been a gradual movement to use experts for eyewitness identifications, the major cause of exonerations. The article proposes a similar movement for informant testimony.

Professor Bloom is also the author of the book Ratting: The Use and Abuse of Informants in the American Justice System (2002).
