The U.N. Human Rights Office has called into question Japan's possible execution of Aum Shinrikyo cult figures on death row who are seeking a retrial.
"We do note that some of the defendants in this case are reportedly requesting a retrial," Ravina Shamdasani, spokeswoman for the office, said in a written interview with Kyodo News.
"Execution of individuals with appeals or other proceedings still pending is against the U.N. Safeguards Guaranteeing Protection of the Rights of Those Facing the Death Penalty," she said.
Death sentences have been finalized for 13 members of the cult, including Aum founder Shoko Asahara, 63, who masterminded the 1995 sarin nerve gas attack on the Tokyo subway system that killed 13 people and left over 6,000 people ill.
Earlier this month, the Justice Ministry transferred seven of the 13 on death row from the Tokyo detention center to other facilities across the country, likely bringing them a step closer to execution.
Japan has long tended to avoid executing death-row inmates while their retrial pleas were pending, but last year then-Justice Minister Katsutoshi Kaneda said such a plea does not impede an execution.
All 13 inmates sentenced to death for crimes committed while members of the doomsday cult, including Asahara, whose real name is Chizuo Matsumoto, had been housed in the Tokyo detention facility. Asahara remains in the facility, government sources said earlier.
The U.N. safeguards, adopted in 1984, partly stipulate that capital punishment "shall not be carried out pending any appeal or other recourse procedure or other proceeding relating to pardon or commutation of the sentence."
"The U.N. Human Rights Office advocates for full abolition of the death penalty, and we have in our discussions with the Japanese government urged them to consider abolition," the spokeswoman said.
