УДК 351.82 Maslovskiy P.A. (The Federation Council of Russia) SUBSOIL LEGISLATION IN RUSSIA: STEP BY STEP ADJUSTMENT It is considered the russian subsoil legislation requires a large-scale revision in order to bring the regulatory framework in compliance with day-to-day realities, and most importantly to stimulate the development of the subsoil management. As the conceptual review of legislation is a lengthy process, the urgent task of the legislators is to adjust the existing subsoil legislation to current mining and exploration practice. During the current year, the legislative work of relevant committees of the Federation Council and the State Duma concentrated on this urgent task.
