A double referendum was held in Transnistria on 17 September 2006. Voters were asked whether they approved of the possibility of renouncing independence and integration with Moldova, or alternatively independence and a possible future integration into the Russian Federation.
Pro-Moldovan organisations announced before the referendum that they would not recognise its results. Ballots for the referendum were reprinted 3 times, as the chairman of electoral commission, Piotr Denisenko, announced a shrinkage of electorate of 7% compared with previous year.
Of the total of 394,861 registered voters, the voter turnout was 78.6%, substantially more than the 50%+1 required by law to validate the referendum. On the day of the referendum, no exit polling was allowed within 25 meters of polling stations, to prevent disruption of voting.
International organisations, such as the Organization for Economic Co-operation and Development,European Union,GUAM, and some other countries (Bulgaria, Romania, Ukraine, Turkey, Croatia, Montenegro, Macedonia, Serbia, Albania, Bosnia, Iceland, Norway) did not recognise the referendum.
According to Russian News Agency RIA Novosti, more than 130 international observers monitored the referendum and reported that "they did not register any procedural violations during the secret balloting," and the representative of the Congress of Russian Communities from Moldova declared that the referendum was held according to international standards. However, no internationally recognised monitoring organisations had observers present.
