Deceptive trade practices, FDCPA, and state UDAP claims.
New York courts apply both the U.S. Constitution and the New York Constitution to consumer protection claims. When state protections are broader than federal ones, New York judges follow the state rule. When they are equal or narrower, federal precedent controls under the Supremacy Clause.
Federal cases governing consumer protection include controlling U.S. Supreme Court decisions and binding precedent from the federal circuit covering New York. Civil remedies most often proceed under 42 U.S.C. § 1983, with defenses including qualified immunity.
