"Should Russia’s Constitutional Court find a decision by the Strasbourg-based court to be in violation of the Constitution, it will not be enforced," Judge Sergei Marvin announced.
The issue was raised following the ECHR's decision to award $2 billion in compensation to shareholders of the now defunct Yukos oil firm after it was purchased by the state-run Rosneft energy company. Stakeholders said the purchase was not conducted equitably.
Judge Marvin said on Tuesday the court had not yet reviewed the ECHR decision on Yukos since it had not been filed to the Constitutional Court. Only a local Russian court reviewing the ECHR ruling or the Russian government are authorized to initiate a revision in the high court, he explained.
"The Constitutional Court has not been asked to do this," the judge noted, adding that Russian authorities could send in a request to screen the ruling.
Following the announcement, the spokesman for Russian President Vladimir Putin, Dmitry Peskov, said the Constitutional Court’s decision on ECHR jurisdiction "is not subject to appeal."
In July 2014, the Strasbourg court ruled that Russia must pay loss compensation to Yukos shareholders, prompting France and Belgium to freeze some assets of the Russian state, although they were later unblocked. The Russian Justice Ministry said it would not follow the ECHR ruling because compliance would put the ministry in breach of Russia’s constitution.
