Mark Zeno is the Senior Supervising Attorney at the Center for Appellate Litigation, a not-for-profit law firm representing clients in appeals and post-conviction proceedings in Manhattan and the Bronx. He has been with the Center since it was founded in 1997. Before joining the Center, Mark was associate appellate counsel with New York’s Legal Aid Society, Criminal Appeals Bureau. 

Mark has represented clients convicted of offenses from simple trespass to first-degree murder, regularly argues appeals in New York’s Appellate Divisions, and the New York State Court of Appeals, and has litigated state post-conviction proceedings at every level of New York State court, and Federal habeas corpus proceedings in the Southern District of New York, and the Second Circuit Court of Appeals. 

In recent years, Mark’s been lead advocate in some of New York’s most significant criminal appellate cases. Illustrative are People v. Santos Suarez, and People v. Darrell Williams. In Suarez, the New York Court of Appeals reformulated the elements of depraved indifference murder, dismissing his client’s second-degree murder conviction. In Williams, the same court struck down the statewide practice of adding post-release supervision to offenders’ sentences after they had been released from prison, resulting in the amelioration of Mr. Williams’ sentence, as well as the sentences of hundreds of other offenders across the state. This past year, Mark launched a project partnering the Center with the Immigrant Defense Project, and pro bono counsel from the firm of Kramer Levin, to assist non-citizen offenders challenge their guilty pleas in the wake of the United States Supreme Court’s decision in Padilla v. Kentucky.

Mark is also a frequent CLE lecturer on New York criminal law and appellate practice, on topics ranging from Rockefeller Drug Law Reform to double jeopardy.
