Dozens of Papua New Guinea men who were sentenced to life imprisonment for sorcery-related killings in 2014 will have their sentences reviewed.
Permission has been granted by PNG's Supreme Court for a review into the country's largest criminal class action appeal.
The 89 men were part of a group that killed seven people during an attack on villagers suspected of practicing sorcery near Ramu.
They were handed their life sentences in July.
Loop PNG reported the 89 men filed an application seeking leave for the review.
Eight prisoners sentenced to death will also reportedly be pursuing a similar action in the courts.
