Survey of Harm to Cooperators: Final Report

At the request of the Court Administration and Case Management Committee, the Criminal Law Committee, and the Committee on Defender Service, the FJC surveyed federal district judges, U.S. Attorney’s Offices, federal defenders, Criminal Justice Act (CJA) district panel representative’s offices, and chief probation and pretrial services offices about harm or threat of harm to government cooperators. Respondents reported a minimum of 571 instances of harm to defendants/offenders and witnesses in the past three years. Cases often involved harm to both defendants/offenders and witnesses. Respondents most often reported threats of physical harm to defendants/offenders or witnesses and to friends or family of defendants/offenders or witnesses. Defendants were most likely to be harmed or threatened when in some type of custody, while witnesses were either in pretrial detention or not in custody at the time of harm or threat. Respondents frequently reported court documents or court proceedings as the source for identifying cooperators. Concerns about harm or threat affected the willingness of both defendants/offenders and witnesses to cooperate with the government in the past three years. Overall, respondents generally agreed that harm to cooperators was a significant problem and that more needed to be done to protect cooperators from harm.

Survey of District Court Judges on a Proposed Amendment to Federal Rule of Evidence 801(d)(1)(B) Concerning Prior Consistent Statements

This report was prepared for the Advisory Committee on the Federal Rules of Evidence. Under the current version of Fed. R. Evid. 801(d)(1)(B), prior consistent statements are admissible for their substance as well as for their rehabilitation only if they rebut recent fabrication because they occurred before the fabrication motive. If a prior consistent statement is admissible for credibility but not admissible for substance, the opposing party is entitled to a jury instruction. Because of perceived difficulties with such an instruction, an amendment to Rule 801(d)(1)(B) was proposed to the Evidence Rules Committee. This paper reports the results of an FJC survey of district judges on matters related to the proposed amendment.

Survey of Bankruptcy Judges Regarding Use of Rule 7026 Mandatory Disclosure in Adversary Proceedings

Rule 26 of the Federal Rules of Civil Procedure requires each party to disclose to the other, at specified time intervals, a variety of information about their case. These mandatory disclosures are covered by Rule 26: (a)(1) initial disclosure, (a)(2) expert testimony disclosure, and (a)(3) pretrial disclosure. Civil Rule 26 is made applicable to adversary proceedings (APs) in bankruptcy by Rule 7026 of the Federal Rules of Bankruptcy Procedure. Rule 26 is Appendix 1. The Advisory Committee on Bankruptcy Rules asked the Federal Judicial Center to survey bankruptcy judges about whether the Committee should recommend an amendment to Bankr. Rule 7026 to exempt certain categories of APs from the mandatory disclosure requirements of Rule 26. These survey results were submitted to the Judicial Conference Advisory Committee on Bankruptcy Rules in March 2004.
