The article illustrates the main concerns associated with the process of introducing amendments to the Constitution of the Sakha Republic (Yakutia). The process of amending a constitution of a constituent part of the Russian Federation is regulated both by federal law and the local laws of individual entities. It’s worth noting, that local legislation does not regulate the entire process of constitutional change (e.g. drafting the amendments). A constituent entity’s authority to introduce constitutional amendments is derived from the authority wielded by the Federation. The limits of such amendments are therefore established by the 1993 Constitution of the Russian Federation and its fundamental systemic principles, that have to be respected by individual entities. The Constitution of the RF does not establish a procedure for adopting a constitution by its constituent entities, although federal legislation does regulate some elements of this process. The Constitution of the Sakha Republic (Yakutia) adopted on April 4 1992 can be classified as an inflexible constitution – similar to the constitutions of other entities. Its amendment process is regulated by the Constitution of the Sakha Republic (Yakutia) as well as the constitutional act of June 15 2002 “On the procedure of adopting the Constitution of the Sakha Republic (Yakutia) ‘On introducing amendments and supplements to the Constitution of the Sakha Republic (Yakutia)’”. The current regulation distinguishes between adopting a new constitution and introducing amendments to a constitution that’s currently in force, although neither the Constitution nor existing regulations specify such differences.
