Munyaneza is appealing the 2009 court decision that handed him a life sentence.
Munyaneza was the first person to be convicted under Canada's relatively recent Crimes Against Humanity and War Crimes Act.
More than 800,000 Rwandans died in the genocide. Munyaneza, a Hutu from Butare, Rwanda, was accused of murdering and raping civilians, and of leading attacks against ethnic Tutsis at the National University of Rwanda during the genocide.
On Oct. 29, 2009, Judge André Denis sentenced Munyaneza to life in prison without possibility of parole for 25 years.
