Evidence Relevant to a Reason to Fabricate is Never Collateral

The Third Department noted that the trial court erred (harmless) when it prohibited defendant from questioning witnesses against him (Corsi and Beebe) about grievances and a lawsuit defendant had filed.  Evidence of a witness’ reason to fabricate should not have been excluded as collateral:

…County Court improperly denied his motion requesting permission to question Corsi and Beebe about prior notices of discipline, grievances filed by defendant and defendant’s pending federal lawsuit … .  The court concluded that the issues were collateral and would be precluded unless the door were opened by a witness’s testimony reflecting bias or hostility toward defendant.  While “trial courts have broad discretion to keep the proceedings within manageable limits and to curtail exploration of collateral matters,” “extrinsic proof tending to establish a reason to fabricate is never collateral and may not be excluded on that ground”… .  People v Hughes, 105838, 3rd Dept 11-27-13
