Title:
Dissolution_of_the_Soviet_Union

Context:
On December 12, the Supreme Soviet of the Russian SFSR formally ratified the Belavezha Accords and renounced the 1922 Union Treaty. The Russian deputies were also recalled from the Supreme Soviet of the USSR. The legality of this action was questionable, since Soviet law did not allow a republic to unilaterally recall its deputies. However, no one in either Russia or the Kremlin objected. Any objections from the latter would have likely had no effect, since the Soviet government had effectively been rendered impotent long before December. In effect, the largest and most powerful republic had seceded from the Union. Later that day, Gorbachev hinted for the first time that he was considering stepping down.

Question:
When were the Belavezha Accords ratified?

December 12
