The head of the State Duma (parliament) Environmental Committee filed a similar case. Two months later, the Russian Supreme Court agreed with Mischenko and the other Ecojuris attorneys who argued that an environmental impact assessment is indeed necessary. This was the first environmental victory in Russia involving the interest of a multinational corporation.
Mischenko challenged the control-and-conquer climate of post-Cold War Russia by bringing the first lawsuits against the government in defense of citizens’ environmental and health rights. She has focused primarily on the enforcement of environmental legislation, the environmental impact assessment process, and ensuring citizen participation in the review of development projects. Leading a group of lawyers and experts, Mischenko helped Ecojuris claim the first legal victory for Russia’s environment in 1992 by stopping the construction of a huge thermoelectric power station. Eventually the plant was built; however, it is considered one of the best in Europe for utilizing modern gas technology.
A February 1998 decision in an Ecojuris case marked the first time in Russian history that a lawsuit in defense of public ecological interests triumphed in the Supreme Court. The case challenged numerous governmental decrees. One such directive would have allowed clear-cutting and development of 20,000 hectares (approximately 50,000 acres) of previously protected forest. Having been issued without an environmental impact assessment, the directive was in violation of existing laws. After the head of the State Duma filed a similar case concerning an additional 18,000 hectares, the Russian Supreme Court ruled that the directives were illegal and three decrees were annulled.
Mischenko is also the creator of the Russian Network of Environmental Lawyers, a group of attorneys from across the country who do pro bono environmental work, and has helped draft environmental legislation for the Russian State Duma.
