Who Issues Warrants in Lockport
In New York an arrest warrant is signed by a judge. For Lockport that means the Niagara County Supreme and County Courts, which hear divorces and major civil cases in the Supreme Court, felonies in the County Court; the city, town and village courts, which take misdemeanors, traffic cases and small claims, issue their own warrants on the cases before them.
When a defendant misses a court date the judge issues a bench warrant, and either kind of warrant lives in the court file of the case, kept by the County Clerk.
