Our lawyers have extensive experience in criminal prosecution and defense, having served as prosecutors at the federal, state, town, and village levels, in addition to defending clients charged with crimes in state and federal court.  William McDonald leads our Criminal Defense practice, drawing on nearly a decade of experience as an Assistant District Attorney in both Nassau and Suffolk Counties, during which time he also served as a Special Assistant United States Attorney for the Eastern District of New York.

State and Federal Criminal Defense

Our depth of experience and firsthand knowledge of government strategy make our Long Island criminal defense attorneys uniquely suited to assess a client’s case and prepare a defense for any state or federal criminal charges.  Our team handles felony matters including gun possession, DWI, assault, robbery, drug possession and sale, manslaughter, murder, and conspiracy, as well as misdemeanors and violations.

Modern trials and appeals have shown how older notions of “reliable” evidence have been discredited through modern science.   Investigators and prosecutors still sometimes rely on discredited evidence and methodology to build cases against defendants.   Our firm takes a scientific approach to challenging test results, eyewitness reliability, and conclusions drawn from evidence seized.  We have the benefit of collaborating with our experts to prepare for examination of scientific evidence, allowing us to delve more deeply into technical issues than many criminal attorneys.  To help keep flawed evidence out of the courtroom, our team stays abreast of the latest scientific studies as they apply to criminal defense.

DWI

DWI is one of the most widely prosecuted crimes on Long Island, and nowhere is a scientific defense more important than in DWI cases.  Our experienced attorneys have seen both sides of the courtroom on over 1,000 DWI cases on both the misdemeanor and felony levels, allowing us to carefully analyze each step in a DWI prosecution to best help the client challenge the initial stop, the police officer’s observations, the administration of Standardized Field Sobriety Tests (SFST), and the chemical tests of blood or breath.

Prevailing Wage Disputes

The firm assists clients in compliance with prevailing wage requirements on public works projects.  As part of such representation, we have defended contractors, subcontractors, builders, and other industry professionals in negotiation and litigation with regard to federal, state, and local prevailing wage laws and regulations, as well as wage deduction, overtime, spread of hours, and other wage-related matters with a criminal component.

Criminal Appeals

Clients and fellow attorneys trust CMM with appeals involving critical issues stemming from the criminal justice system.  We have argued state and federal appeals involving constitutional, procedural, and evidentiary issues in state and federal court, including New York’s highest court, the Court of Appeals.  Our work also includes collaboration with trial counsel as trials progress to ensure the proper preservation of issues for eventual appellate review.  Fellow lawyers regularly seek our counsel on strategy during criminal trials or to handle appeals once a trial is over.  The department is comprised of lawyers who built their careers on appellate advocacy and criminal defense.

The firm also has a busy White Collar Defense & Investigations practice and also defends healthcare professionals in criminal matters and governmental investigations.
