Supreme National Tribunal

The Supreme National Tribunal (Najwyższy Trybunał Narodowy, NTN) was a war crime tribunal active in Poland from 1946 to 1948. The Tribunal aims and purpose were defined by the State National Council in the Decrees of 22 January and 17 October 1946 and 11 April 1947. The new law was based on the earlier Decree of 31 August 1944 issued by the new Polish pro-Soviet government, with jurisdiction over fascist-hitlerite criminals and traitors to the Polish nation. The tribunal presided over seven high-profile cases (of 49 individuals total).

Background
Nazi Germany occupied Poland in 1939 and carried out many atrocities. The 1943 Moscow Declaration stated that Germans judged guilty of war crimes would be sent back to the countries where they had committed their crimes and "judged on the spot by the peoples whom they have outraged". Poland, which suffered heavily due to Nazi atrocities, identified over 12,000 criminals it requested to be extradited; eventually about 2,000 German criminals were extradited to Poland (from 1945 onwards, most before 1949).

The Polish Underground State had its own Special Courts in occupied Poland, which tried and passed sentences on some German war criminals. Polish communist authorities (of the Polish Committee of National Liberation, PKWN) who did not recognize the Underground State (and in some cases actively persecuted people connected with it) established its own alternative structure, which with the victory of the communist authorities over the Underground State became dominant in post-war Poland. PKWN authorities authorized the establishment of the Special Criminal Courts on 12 September 1944 to try German war criminals. On 22 January 1946, the single-instance Supreme National Tribunal was formed, with a mission to try the main perpetrators of crimes committed by the Third Reich in the occupied Polish territories.

Jurisdiction and powers
The jurisdiction and powers of the tribunal were defined in Decrees of 22 January and 17 October 1946 and Decree of 11 April 1947. The law applied was a Decree of 31 August 1944, concerning the punishment of fascist-hitlerite criminals guilty of murder and ill-treatment of civilian population and of prisoners of war, and the punishment of traitors to the Polish Nation.

There was no appeal from the verdicts of the tribunal.

Composition of the tribunal
The tribunal had three judges, four members of jury, procurators and defenders.

The best known judge was Emil Stanisław Rappaport.
