An interesting fact just brought to my attention: Czech and Slovak Orthodox Church was first granted autocephaly by Moscow and only later was the autocephaly accepted by Constantinople. Constantinople’s claim that Moscow had no authority to grant autocephaly is inconsistent with its own practice it appears.
From the Wikipedia article on the Czech and Slovak Orthodox Church:
After World War II the Orthodox Church in Czechoslovakia began its recovery without its beloved bishop. On December 9, 1951, the Patriarch of Moscow granted autocephaly to the Orthodox Church of Czechoslovakia, though this action was not recognized by Constantinople, which regarded the Czechoslovakian church as being autonomous under its authority. The Patriarch of Constantinople later granted a tomos of autocephaly on August 27, 1998.
