John H. Cunha Jr.

Boston, Massachusetts

John H. Cunha Jr. focuses on litigation, trial and appellate, civil and criminal. He is a former clinical instructor at Suffolk and Harvard Law Schools.  He is admitted to practice in Massachusetts, New York, The U.S. District Court for Massachusetts, the U.S. First Circuit Court of Appeals, and the U.S. Supreme Court.

Jack represents clients charged with a broad variety of offenses, including homicide trials and federal complex federal crimes. In a RICO case in which he prevailed, U.S. v. Green, his Daubert challenge to so-called ballistics testimony precluded government "experts" from testifying that they had determined crucial evidence from a shooting scene matched a handgun linked to his client. Mr. Cunha also litigated Com. v. Patterson in the trial and appellate courts, in which a Daubert challenge led to exclusion of "simultaneous" fingerprints, the key evidence against his client charged with the murder of a Boston police detective.

He lectures nationally, for example, the National Institute of Justice, Massachusetts Continuing Legal Education, the National Association of Criminal Defense Attorneys, Federal Defenders national training seminars, Harvard Law School, and various CLE programs, on criminal defense in general and forensic evidence in particular.

Jack served as President of the Massachusetts Association of Criminal Defense Lawyers from 2009-2011, and has been a member of its Board of Directors since 1995.
