JOHN H. CUNHA, JR., is a partner at the Boston law firm of Cunha & Holcomb, PC. His practice focuses on litigation, particularly criminal defense, trial, and appellate. He is a former clinical instructor in criminal law at Suffolk and Harvard law schools. Cunha has represented clients charged with a broad variety of offenses, including many homicide trials and appeals. In the last eighteen months, he has prevailed in three federal prosecutions, including two RICO cases. In one, U.S. v. Green, his Daubert challenge to so-called ballistics testimony succeeded in precluding government “experts” from testifying that they had determined crucial evidence from a shooting scene matched a handgun linked to his client. Cunha also litigated Commonwealth 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 in a prosecution for the murder of a Boston police detective. He also brought a Daubert/Lanigan challenge in the Superior Court to so-called ballistics evidence. He has lectured for Massachusetts Continuing Legal Education, Inc. and at bar association symposia. He is a member of the board of directors of the Massachusetts Association of Criminal Defense Lawyers. (September 2007)
