Mr. Benno began his legal career as an Assistant District Attorney at the esteemed Manhattan District Attorney’s Office, where, under then-District Attorney Robert Morgenthau, he served in both the trial division and the appeals bureau. In the trial division, Mr. Benno investigated and prosecuted violent and white-collar crimes and tried several jury trials to verdict, all as primary chair. In the appeals bureau, Mr. Benno handled all aspects of criminal appeals, and regularly submitted arguments to the New York State Court of Appeals, New York State’s highest tribunal.
After several years as an Assistant District Attorney, Mr. Benno left government service to work for a premier civil litigation law firm where he tried civil cases and managed a caseload that focused on civil rights matters in state and federal court.
In 2009, Mr. Benno opened his own law practice, which focused on civil rights cases in state and federal court, criminal defense, and appellate litigation.
In addition to an active trial practice, Mr. Benno has briefed and argued criminal and civil appeals in the First, Second, Third, and Fourth Departments of the New York State Supreme Court, Appellate Division, the New York State Court of Appeals, and the United States Court of Appeals for the Second Circuit.
In 2010, Mr. Benno argued People v. Mothersell in the New York State Court of Appeals, New York State’s highest tribunal. That case, which challenged the constitutionality of the City of Syracuse’s usage of “all persons present” search warrants, resulted in a unanimous reversal of the client’s criminal conviction and the dismissal of his indictment, and changed the landscape of criminal law practice in New York State. More recently, Mr. Benno was lead counsel in Bailey v. Pataki, a Section 1983 civil rights action against former New York State Governor George Pataki and several members of his administration for creating and implementing an unconstitutional civil commitment policy for a class of prisoners. Mr. Benno briefed and argued the interlocutory appeal in that case to the Second Circuit Court of Appeals. He won that appeal, and thereafter tried the case in the United States District Court for the Southern District of New York. After a three and a half week trial, the jury found a top member of Gov. Pataki’s administration liable for violating the plaintiffs’ constitutional rights.
From 2006 through 2012, Mr. Benno was an adjunct professor at New York Law School, where he taught Legal Reasoning and Writing and Written and Oral Advocacy.
