The family of a Libyan man convicted of the 1988 Lockerbie bombing is launching a fresh effort to posthumously clear his name.

Relatives of Abdelbaset al-Megrahi say he was wrongly convicted of the airliner bombing, which killed 270 people.

The family’s lawyer, Aamer Anwar, handed a dossier of evidence to the Scottish Criminal Cases Review Commission in Glasgow on Tuesday. The commission will decide whether to hand the case to an appeals court.

Al-Megrahi was convicted in 2001 of blowing up Pan Am Flight 103 over the Scottish town of Lockerbie on Dec. 21, 1988, killing all 259 people aboard and 11 on the ground.

Al-Megrahi lost one appeal and abandoned another before being freed in 2009 on compassionate grounds. He died of cancer in 2012, still protesting his innocence.
