Judges presiding over the landmark genocide trial of a former dictator have asked the Constitutional Court to decide if it should continue.

Tribunal president Yasmin Barrios says judges overseeing the trial won't accept another judge's ruling that the case should start over, at a point before charges were filed against Efrain Rios Montt. The Constitutional Court has 10 days to rule on the dispute.

The trial had been nearing closing arguments and U.N. spokesman Martin Nesirky said Friday that the U.N. High Commissioner for Human Rights Navi Pillay is concerned over the suspensión.

Nesirky says it "is a blow to the numerous victims of the atrocities committed during Guatemala's civil war."

Rios Montt is accused in the killing of 1,771 indigenous people after taking power in a 1982 coup.
