In 1990, on behalf of the Federal Bar Association's Democracy Development Initiative, Dzurilla spent two months in Moscow, Russia as an advisor to the Russian Constitutional Commission, which was preparing the first non-socialist constitution of the Russian Federation. The commission was chaired by Russian president Boris Yeltsin, and Dzurilla worked closely with Oleg Rumyantsev, the chairman of the commission's working group. The commission's work led to the enactment of the 1993 Constitution of Russia. However, as a result of the 1993 Russian constitutional crisis, the final version differed from the commission's draft by substantially increasing the powers of the president.
