The New York Court of Appeals denied a request from a defendant Tuesday to set aside his plea agreement with prosecutors on murder and assault charges after he said he didn’t understand to what extent he would have to cooperate with law enforcement in a different case involving his family.

Alexis Rodriguez, who plead guilty to those charges as part of the deal, was seeking to have his plea agreement withdrawn because he was afraid his testimony against another individual would put his family’s safety at risk, according to a dissent against the court’s decision.
