But conflict between President and Congress made passage of that draft less likely: the Congress shifted onto more and more rewriting of the 1978 Russian Constitution, while President pushed forward with new draft Constitution, which doesn't define state symbols. After 1993 Russian constitutional crisis and just one day before the constitutional referendum (i.e. on December 11, 1993) Yeltsin, then President of the Russian Federation, issued a presidential decree on December 11, 1993, retaining "Patrioticheskaya Pesnya" the official anthem for Russia, but this decree was provisional, since the draft Constitution (which was passed a day later) explicitly referred this matter to legislation, enacted by parliament. According to Article 70 of the Constitution, state symbols (which are an anthem, flag and coat of arms) required further definition by future legislation. As it was a constitutional matter, it had to be passed by a two-thirds majority in the Duma.
