Judith Clark, who as a young woman was part of a violent left-wing movement and participated in a fatal botched robbery of a Brink’s armored car in 1981 in Rockland County, N.Y., was denied parole on Friday despite the support of Gov. Andrew M. Cuomo, who ordered her sentence commuted late last year.

Ms. Clark has served 35 years of a minimum 75-year sentence for her role in the notorious crime, which left a guard and two police officers dead and was one of the final acts of rage of a waning movement. She will not be eligible for parole again until April 2019.

The decision not to release Ms. Clark, 67, from prison was something of a blow for Mr. Cuomo, who took the politically risky decision to commute her sentence, making her eligible for parole, saying that she had made “exceptional strides in self-development.”

Speaking at the funeral of the former Daily News columnist Jimmy Breslin in March, he went further.

“It was a hard political decision,” Mr. Cuomo said. “I could hear Jimmy’s voice saying, ‘She made a mistake — we all do. She learned, she paid the price, she spent her life in a cage, and she is now different. Jesus would pardon her. Who the hell made you better than Jesus?’”
