 This results in the fact that most of the assizes trials held, involve a homicide (murder or manslaughter) or other crimes of a grave nature.In this capacity, some extraordinary crimes against international law, such as genocide or crimes against humanity, are also tried by the courts of assizes.Aside from the most serious crimes, article 150 of the Belgian Constitution also establishes that political crimes and press crimes (except those inspired by racism or xenophobia) have to be tried by a jury.
