Legal Adviser to Extraordinary Chambers in the Courts of Cambodia Constanze Oehlrich yesterday said assistance from international communities for evidence and investigation is necessary to ensure legitimate and transparent trial of war crimes.

It is very difficult to investigate such a large-scale crime and Cambodia needs to have additional capacity and support to make the trial legitimate and transparent, she said describing the Cambodian model.

“There is international experience in trying war criminals across the globe. In dealing with such a huge issue you need to be very pragmatic; you need to coordinate and organise the evidence,” said Constanze Oehlrich.
