The success of the military operation in the Japanese embassy hostage crisis was tainted by subsequent allegations that at least three and possibly eight of the insurgents were summarily executed by the commandos after surrendering. In 2002, the case was taken up by public prosecutors, but the Peruvian Supreme Court ruled that the military tribunals had jurisdiction. A military court later absolved them of guilt, and the "Chavín de Huantar" soldiers led the 2004 military parade. In response, in 2003 MRTA family members lodged a complaint with the Inter-American Commission on Human Rights (IACHR) accusing the Peruvian state of human rights violations, namely that the MRTA insurgents had been denied the "right to life, the right to judicial guarantees and the right to judicial protection". The IACHR accepted the case and is currently studying it.
