Patrick Casey’s article, “Immunity Issues in Federal and Pennsylvania Criminal Law and Practice,” was published by The Pennsylvania Bar Association Quarterly on July 8, 2025, Vol. XCVI, Issue 3, p. 189.   The article discusses the legal standards for statutory immunity in federal and Pennsylvania courts.  It addresses the pitfalls of contractual agreements granting limited immunity.  The article provides practical examples of the many versions of “use” by the government which are violative of federal and state statutes. The article recognizes that the Pennsylvania Constitution provides greater protection form compelled evidence production than does the United States Constitution. Finally, critical differences in burdens of proof and obligation to prove wholly independent sources are explained.
