In a bombshell move, Gov. Andrew Cuomo on Friday commuted the 75-year-to-life sentence of Judith Clark, the former Weather Underground radical who was convicted for her role in the infamous 1981 Brinks robbery in which two Nyack police officers and an armored truck driver were killed.

The clemency from the governor allows Clark, 67, to appear before the Parole Board for release in early 2017.

In a press release, the governor said Clark — who has been a model prisoner — would not have been eligible for parole under her “extraordinarily long” sentence until she was 106 years old, “leaving her without an opportunity to appear before the Parole Board during her natural lifetime.”

Cuomo noted that Clark had served 35 years in the slammer.

“We applaud the governor for his heroic action,” said Allen Roskoff, a Manhattan activist who has long campaigned for Clark’s clemency and release.

On Oct. 14, 1983, she was convicted of murder in the second degree and robbery in the first degree in Rockland County for driving the getaway vehicle in the armored car robbery.

Clark, who did not have a lawyer present, had received one of the longest sentences of her six co-defendants, the majority of whom are either deceased or no longer in custody.

She received the same sentence as one of the known shooters, Cuomo said.

Her only female co-defendant, Kathy Boudin, whose participation in the underlying crime was similar to Clark’s, received a 20-year minimum sentence and was paroled in 2003, and then discharged from parole supervision in 2010.

While at Bedford Hills prison, Clark made “exceptional strides in self-development,” Cuomo’s release said.

She earned bachelor’s and master’s degrees from Mercy College, and has an extensive prison programming record including teaching prenatal parenting courses in the Nursery Program, founding an HIV/AIDS education program, training service dogs in the Puppies Behind Bars program, and serving as a college tutor.

She maintained a perfect disciplinary record and lives in honor housing.

Clark has written letters to Cuomo requesting leniency and was passed over two years ago.

“I was 31 years old at that time, and had spent my entire young adult life wrapped in increasingly isolated, self-contained radical organizations and activities. While other co-defendants fought their cases legally, I refused to participate in my trial and went unrepresented,” she said.

“While my life is fueled by a hope-filled commitment to repair, I never forget that the lives lost on October 20, 1981, cannot be brought back. I live each day with sorrow, shame and regret for my role in the deaths of Peter Paige, Edward O’Grady and Waverly Brown.”

Clark said she renounced her self-avowed “political prisoner” status and publicly apologized for her part in the heinous crime.

“I look at the world differently now. Instead of abstract slogans, I see and am moved by flesh-and-blood people. I hope that my contrition, which was so publicly absent during the trial, and my long record of taking responsibility through sincere change and work on behalf of others, will bring some solace.”

“I am seeking a second chance — to live in society as a responsible, contributing member. I ask you to consider me worthy of reconsideration, compassion, and clemency,” she said.

Boudin — who spent 22 years in prison — received an adjunct professorship at Columbia University’s School of Social Work after her release. Her academic role had outraged the widow of one of her victims, Brinks guard and dad of three Paige.

The 2012 Robert Redford movie “The Company You Keep” was loosely based on the infamous heist, in which Boudin acted as a getaway driver.
