Amir, 47, was sentenced to life in solitary confinement in prison for the murder, which occurred after a peace rally in Tel Aviv. Amir confessed to shooting Rabin and reenacted it for police.
He opposed Rabin’s territorial concessions, a condition of the Oslo Accords, which Rabin signed with then-Palestine Liberation Organization leader Yasser Arafat.
His wife, Larissa Trimbobler, whom he married in a proxy ceremony while in prison, in a Facebook post on Saturday said that Amir would seek a retrial.
“I wish to update that, at this time, a legal defense team is being assembled to prepare and submit a request for a retrial for Yigal Amir,” the Facebook post reportedly said. “The move is being taken with permission and authorization after Yigal Amir gave his consent.”
Amir and Trimbobler, who were married in 2004, were permitted conjugal visits and have an 11-year-old son.
In a second Facebook post Sunday Trimbobler reportedly wrote that Amir’s defense lawyers have evidence that the bullets he fired at Rabin did not cause his death.
Earlier this month more than 80,000 people gathered in the same Tel Aviv square where Rabin was killed to commemorate his assassination.
