Before the assembly vote session in Strasbourg, the amendment on stripping Russia of the right to vote and excluding it from PACE governing bodies further in 2015 was supported by a parliamentary committee.

“The amendment that the Russian delegation has been again deprived of the right to vote, to participate in the governing bodies of the Assembly – the Bureau, Presidential and Permanent committees – was passed by one vote, 35 for and 34 against,” said the deputy head of the Russian delegation, Leonid Slutsky.

Slutsky said the committee’s vote came as an “unpleasant surprise” since initially the amendment was turned down by a majority. Thus Austrian delegate Stefan Schennach, who chairs the PACE monitoring committee, argued that the Ukrainian conflict cannot be resolved "without the full-fledged participation and the political will of Russia."

“The rapporteur on Russia’s credentials, Stefan Shennah, recognized [the amendment] as destructive and destroying the entire architecture of the resolution," Slutsky said.

Russian lawmakers have previously said that Moscow will leave PACE if its rights are not restored in 2015.

"If the sanctions against the Russian delegation, imposed last April, are renewed, if Russia is stripped of its right to vote and participate in the assembly's leading bodies, we will leave PACE and suspend our membership until the end of 2015," Aleksey Pushkov, Russia’s PACE delegation head and chairman of the State Duma's lower house foreign affairs committee, said Tuesday.

Last April, PACE suspended Russia’s right to vote and excluded it from leadership positions, until the end of 2014 in retaliation for Crimea voting to join Russia. The Russian delegation did not attend the session to protest the motion.

Russia was stripped of its PACE voting rights in April 2000 in connection with a counter terrorism operation in Chechnya. Moscow's rights were fully reinstated the following year.
