Relevant New York Laws
NY Penal Law — New York's principal criminal statute, classifying offenses as violations, misdemeanors (Class A and B), and felonies (Classes A through E). Penalties range from fines and conditional discharges to mandatory state prison sentences for violent felonies and predicate-felony offenders under Penal Law Article 70.
NY Vehicle and Traffic Law § 1192 — Governs Driving While Intoxicated (DWI), Driving While Ability Impaired (DWAI), and related offenses. § 1192(2) sets the per se BAC threshold of .08 (.04 for commercial drivers), § 1192(2-a) covers Aggravated DWI at .18 or higher, and chemical-test refusals trigger separate civil license-revocation proceedings under VTL § 1194.
NY Penal Law Article 265 — New York's weapons-offense statute. Criminal possession of a firearm and criminal possession of a weapon in the second degree are violent felonies under Penal Law § 70.02, carrying mandatory minimum state prison sentences in most cases — even for clients with no prior record.
NY CPL (Criminal Procedure Law) — Controls arrest, arraignment, bail, discovery, suppression motions, plea practice, and trial. CPL Article 245 (effective 2020) imposes strict, short discovery timelines on the prosecution, and CPL Article 510 governs bail and pretrial release following the 2019–2020 bail reforms.
