1) New York law provides for full disclosure of all material relevant to prosecuting or defending a legal action. School records are generally admissible in trials if authenticated, though privileged family medical information may be redacted. 2) A 1991 case established that school records of a non-party sibling could be discoverable if an expert affidavit demonstrates their potential relevance, such as a genetic link between conditions. Subsequent cases debated whether records of non-party family members require sufficient expert evidence and consideration of privacy. 3) The admissibility of parental and sibling academic records remains decided on a case-by-case basis, balancing relevance, privacy, and whether discovery risks speculative fishing expeditions versus narrowing issues for trial.
