As a result of the allegations, around 250 Cambodian staffers at the tribunal have not received paychecks for the month of July.

Court spokeswoman Helen Jarvis said the checks had been expected July 28 and that she hoped the situation would "actually be resolved very soon."

This is not the first time charges of corruption have been leveled at the court. While the results of a special audit released in April declared court administration "robust and ready to take on the challenges of the next phase of operations," the review failed to investigate previous claims of kickbacks.

The audit had restored some degree of donor confidence in the court -- confidence that could be shaken if these new allegations appear well-founded.

And the allegations could hardly come at a worse time. The court is in the process of lobbying donors for funds and an indictment against Comrade Duch is expected any day. His trial is expected to begin in September, which can't come soon enough for court observers worried the elderly defendants may die before they face the tribunal.

Rosandhaug's response to how these allegations might affect fund-raising: "I am of course concerned."
