I've posted about the Khmer Rouge Tribunal before. The first trial just started. It seems like they're only dealing with procedural issues now, with the substantive legal issues to follow next month. Here are a couple of articles to check out + where to find the official site:
Reuters UK -- http://uk.reuters.com/article/reutersEdge/idUKLNE51F03H20090216
New York Times -- http://www.nytimes.com/2009/02/17/world/asia/17cambodia.html?ref=world
Extraordinary Chambers in the Courts of Cambodia -- http://www.eccc.gov.kh/english/default.aspx
Needless to say, I'll be keeping a close watch on this one.
