Rwanda's widely praised community genocide courts, due to wind up this year, have done nothing to heal ethnic divisions and have been used to bolster government authority, says a report by one of the country's leading aid donors.
The unique "gacaca" courts, which have heard more than a million cases, have been hailed as the centrepiece of Rwanda's miracle recovery from the 1994 genocide, but their reputation has been disputed in a study by Japan's Jica aid corporation.
The courts were touted as an "African solution" that would heal the legacy left by a Hutu-led genocide that killed nearly one in 10 Rwandese, many from the Tutsi minority.
But Jica researcher Shinichi Takeuch says the courts are regarded in Rwanda as handing out "victor's justice", and "have done nothing to ease underlying ethnic tensions in the country".
Nearly a decade after 800,000 people were murdered in a 100-day killing spree, impoverished Rwanda found itself with 135,000 detainees and only 12 courts to process their cases.
