Serbia and Montenegro suspended as a participating State

Conference

Location:: Vienna

It was decided that the suspension would be reviewed no later than 13 October 1992. However, it was not until 7 November 2000 that the former Republic of Yugoslavia would rejoin the OSCE as a participating State.

The "consensus minus one" exception to the OSCE rule of consensus in decision-making can only be used in clear cases of gross and uncorrected violations of CSCECSCE
Conference on Security and Co-operation in Europe commitments. This is the only occasion it has been used.
