The unconditional surrender of the major Axis powers caused a legal problem at the post-war Nuremberg Trials, because the trials appeared to be in conflict with Articles 63 and 64 of the Geneva Convention of 1929. Usually if such trials are held, they would be held under the auspices of the defeated power's own legal system as happened with some of the minor Axis powers, for example in the post World War II Romanian People's Tribunals. To circumvent this, the Allies argued that the major war criminals were captured after the end of the war, so they were not prisoners of war and the Geneva Conventions did not cover them. Further, the collapse of the Axis regimes created a legal condition of total defeat ("debellatio") so the provisions of the 1907 Hague Convention over military occupation were not applicable.
