Mark Zeno is the Assistant Attorney in Charge 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. 

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, litigates 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.  

Mark's clients’ recent appearances in the New York Court of Appeals have resulted in important enhancements to the rights afforded criminal defendants, including People v. Santos Suarez, where the Court reformulated the elements of depraved indifference murder, resulting in the dismissal of Mr. Suarez's murder conviction, and constraining the prosecution of reckless homicide statewide; People v. Darrell Williams, where the Court struck down the then-common practice of correcting offenders' sentences to include post-release supervision even after they had been released from prison, resulting in both the amelioration of Mr. Williams' sentence, and the sentences of hundreds of other offenders across the state; and People v. David Paulin, where the Court extended eligibility for reduced sentences under the Rockefeller Drug-Law reforms to hundreds of parolees. 

Mark’s most recent focus has been launching the Center’s innovative post-conviction program for immigrants, which focuses on helping non-citizen offenders - many of whom who have lived nearly their entire lives in the United States, know it as their own and their family's home, and face deportation for only minor offenses - avoid removal.

Mark is also a frequent CLE lecturer on New York criminal law, ranging from Rockefeller Drug Law Reform to double jeopardy to the intersection of immigration law and criminal law.
