The Khmer Rouge trial, which is known by the clunky name of the Extraordinary Chambers in the Courts of Cambodia, will try only a handful of senior leaders of the Khmer Rouge.
It is a unique international crimes court in structure because it will be operated by the Cambodian government with the assistance of the UN. There is international funding for the trial to be held for three years, starting from this year.
But there is wrangling between Cambodian and international judges and lawyers over the rules covering everything from the defence lawyers to the trial chamber's design.
One report said a foreign co-prosecutor was compiling evidence and the committee drafting internal rules for the hearings was due to meet again next month. A trial might then begin by the end of the year.
The victims wait, as they have for almost three decades, while this debate continues. There are also fears the trial might even be aborted. International lawyers, judges and human rights groups have expressed concern as to whether the trial will be fair, and privately that their own reputations are being put at stake.
