Where do I find New York State case law?
Case law is common law that arises from judicial and comptroller opinions following a dispute or interpretative question of statutory (legislated) law.
For instance, the case law concerning one paragraph of Section 189 goes on for 28 pages in McKinney's Consolidated Laws of New York. A copy of McKinney’s can be found at the County Clerk’s office or it can be ordered directly from West Thomson Reuters
