BELARUS. DEATH PENALTY MIGHT BE ANNULLED VIA A NATIONAL REFERENDUM

July 11, 2005: Belarussian deputy presidential chief of staff Natalya Petkevich said the death sentence might be annulled in Belarus via a national referendum.
"Most of our citizens voiced their opposition to the annulment of capital punishment in a national referendum and we adhere to this decision. But when certain socio-economic, mostly social, conditions are created, the annulment of capital punishment might be considered," Petkevich told a news conference in Minsk.
