The influx of missionaries over the past several years has led to pressure by groups in Russia, specifically nationalists and the Russian Orthodox Church, to limit the activities of these "nontraditional" religious groups. In response, the Duma passed a new, restrictive, and potentially discriminatory law in October 1997. The law is very complex, with many ambiguous and contradictory provisions. The law's most controversial provisions separates religious "groups" and "organizations" and introduces a 15-year rule, which allows groups that have existed for 15 years or longer to obtain accredited status. According to Russian priest and dissident Gleb Yakunin, new religion law "heavily favors the Russian Orthodox Church at the expense of all other religions, including Judaism, Catholicism, and Protestantism.", and it is "a step backward in Russia's process of democratization".
