Reports

“Discovery Reform in New York: What Can the Data Tell Us?” Using data from the Office of Court Administration (OCA) and dividing the state into New York City (Bronx, Brooklyn, Manhattan, Queens and Staten Island), “downstate suburban region” (Nassau, Suffolk, Westchester, and Rockland), and “upstate” (the 53 remaining counties), the report from the Data for Collaborative Justice largely focused on three areas of analysis: (1) whether evidence sharing provisions are associated with an increased dismissal rate; (2) prosecutorial compliance with disclosure timeframes; and (3) whether cases are processed at different rates than before discovery reform. We covered this report in our News Picks from NYSDA Staff June 2, 2025.
