Sweden, Norway, and Denmark submit the Greek case alleging human rights violations by the Greek junta.

In September 1967, Denmark, Norway, Sweden and the Netherlands brought the Greek case to the European Commission of Human Rights, alleging violations of the European Convention of Human Rights (ECHR) by the Greek junta, which had taken power earlier that year. In 1969, the Commission found serious violations, including torture; the junta reacted by withdrawing from the Council of Europe. The case received significant press coverage and was "one of the most famous cases in the Convention's history", according to legal scholar Ed Bates.

The Greek junta or Regime of the Colonels was a right-wing military junta that ruled Greece from 1967 to 1974. On 21 April 1967, a group of colonels overthrew the caretaker government a month before scheduled elections which Georgios Papandreou's Centre Union was favoured to win.
