First Amendment and Defamation Litigation

Sher Tremonte has extensive experience in litigating defamation and other First Amendment-related matters.

Outside the courtroom, the firm helps media clients develop strategies that minimize exposure to defamation lawsuits, providing pre-publication review and counsel to ward off litigation. Our lawyers also counsel clients on ways to mitigate and redress injury caused by false and damaging speech, as well as freedom of speech issues raised by government regulations.
