Joseph D. Steinfield is a trial lawyer, teacher, and writer. Over the span of several decades, he has represented clients in a complex business dispute, First Amendment litigation, construction cases, fraud and chapter 93A cases, intellectual property disputes, wrongful death cases, section 1983 civil rights claims, and commercial disputes of all types. Joe has argued many appeals in both state and federal courts, many of which have established important precedents under both state and federal law.

Joe has represented the media in libel, copyright, access, and privacy cases. He represented a well-known magazine in a landmark case in which the Massachusetts Supreme Judicial Court upheld a claim of First Amendment protection for parody.  He represented a major Boston newspaper in a leading First Circuit case granting access rights. On behalf of a New Hampshire newspaper, he persuaded the New Hampshire Supreme Court to adopt novel procedures under the state’s “Right-to-Know” law. He represented a television network in a high-profile defamation case, and he successfully represented a public television station in a case under the Connecticut shield law.

He has frequently appeared in Puerto Rico federal court, including representing the Governor of Puerto Rico and the University of Puerto Rico in two high-profile First Amendment. With Prince Lobel partner Jeff Pyle, he tried a lengthy case on behalf of a businessman against officials of the Puerto Rico Department of Insurance. The jury returned a multi-million-dollar verdict in favor of his client, which was upheld by the First Circuit Court of Appeals.

In 2000, Joe served as Special Investigator, and then as Special Prosecutor, representing the New Hampshire State Legislature. The case involved claims of judicial misconduct, and after a three-week trial the state senate voted not to convict the impeached Chief Justice of the state.
