 Such a law was passed on 31 March 1992, when Yeltsin and Ruslan Khasbulatov, then chairman of the Russian Supreme Soviet and an ethnic Chechen himself, signed the Federation Treaty bilaterally with 86 out of 88 federal subjects.In almost all cases, demands for greater autonomy or independence were satisfied by concessions of regional autonomy and tax privileges.The treaty outlined three basic types of federal subjects and the powers that were reserved for local and federal government.
