The tribunal's security section has completed an investigation into the recent "Waterlilygate" controversy at the court, spokesman Lars Olsen told reporters Wednesday. He said no evidence of "foul play or theft" had been discovered.

Last week, defense lawyers for Nuon Chea said they believed there had been a security breach at the court after a confidential document from their office was found floating in a lily pond outside the ECCC.

Olsen said the security section is drafting a report about the recent investigation and will be strengthening security protocols.

He also responded to recent criticism of new Victim's Unit head Helen Jarvis. Defense lawyers had claimed Jarvis' affiliations with the Leninist Party Faction made her unfit for her new position.

Quoting from a letter sent by Deputy Director of Administration Knut Rosandhaug to the defense, Olsen read, "every staff has a right to their personal political views."

He wrote that he fully supported Jarvis' appointment and that her political affiliations "were well known before her appointment to head of the Victims Unit."
