A challenge to New York City's enforcement of the laws banning gravity knives has been revived by the U.S. Court of Appeals for the Second Circuit.

The circuit found that two individuals and a business that were prosecuted under state laws §265.0(5) and §265.01(1) have standing to seek declaratory and injunctive relief in the case, Knife Rights, Inc. v. Vance, 13-4840-cv.

The plaintiffs are attacking the enforcement of the laws as vague as applied, saying police filed charges against them for knives that don't qualify as gravity knives.
