The document discusses pre-trial rights under Cambodian, international, and ECCC laws. It outlines rights such as the right to remain silent, legal assistance, interpretation services, and adequate time to prepare a defense. Case studies examine whether rights were properly waived, including the right to counsel during interrogations. The ICTR found Kabiligi did not understand his immediate right to counsel, so his waiver was invalid. The ECCC examined whether Duch and Nuon Chea validly waived their rights during initial questioning.
