through maintenance of leadership of the Constitution and the Supreme interpretation of the Constitution and laws; protection of constitutional laws and freedoms of the person and the citizen; and control if the principle of division of authorities is observed by power structures in their activity [21]. O. Kordun and L. Nalivajko suggest to enlarge the list of powers of the Constitutional Court with the following functions: 1) consideration of constitutionality of activity and acts of political parties; 2) research of constitutionality of elections and referenda [22]. Existence of full regulation of the specified questions will allow to avoid to a certain extent a direct involving of a body of the constitutional jurisdiction in politics. In opinion of Kordun, activity of an unbiased competent body of the constitutional justice capable to remove political tension in a society which by all means arises when political rights of citizens are realized is necessary today [23] .. Ovsepyan objects O. Kordun and L. Nalivajko as orientation of the constitutional courts at interdiction or support of any among political parties destabilizes authority [24]. Moreover, well-known Polish constitutionalist L. Garlitsky asserts that the constitutional justice does not cover such questions as selective disputes, the control of political parties and carrying out of referenda at all [25] .author also considers to be inexpedient to transfer the set of above mentioned functions to the Constitutional Court of Ukraine. This step will result on the institute of the constitutional justice which is swamped with work even now. It is unable to consider operatively and qualitatively a huge stream of cases. First of all, it is connected with complexity of examining and studying of materials of a dispute; it undoubtedly will affect the term of a case investigation. Besides, for the time being there are state bodies which supervise elections and referenda and it is possible to appeal to them against the disputable moments. They are selective commissions, commissions on carrying out of a referendum and courts of general jurisdiction.all scientific workers approve the norm on granting the function of official interpretation of the contents of the Constitution and laws of Ukraine to the Constitutional Court of Ukraine. Carrying out such an interpretation the body of the constitutional control itself acts as an active subject of legislature [26] .. Selivanov is against transfer of functions of official interpretation of the Constitution and laws of Ukraine to regulatory authority. He considers that the decision on the dispute on conformity of statutory acts to a principle of leadership of law should belong to the Constitutional Court. The body independent of Parliament can impartially solve questions on constitutionality of laws and other statutory acts of the Supreme Rada of Ukraine, acts of the President of Ukraine, acts of the Cabinet of Ukraine, legal acts of the Supreme Rada of Autonomous republic Crimea; conformity of current international contracts which are brought before the Supreme Rada of Ukraine for granting the consent on their compulsion to the Constitution of Ukraine; observance of the constitutional procedure of investigation and consideration of a case about elimination of the President from the post by way of impeachment. Such an approach is explained simply - nobody can be the judge in his/her own business [27] .. Gergelijnyk also supports restriction of functions of the Parliament by the Constitutional Court of Ukraine. In his opinion the body of the constitutional control in the system of the state institutes will play the major role as it provides equation of functioning of executive and legislative bodies. The control institute through independent interpretation provides exact carrying out of the Constitution and other statutory acts, strengthens their role as regulators of the life of a society and state [28]. V. Tihy adds: preservation by the Supreme Rada of Ukraine of the function of interpretation of the Constitution and laws of Ukraine not only creates a threat of modification in these statutory acts with the purpose of granting of a return action by them, but also deprives the decision of the Constitutional Court with their finality, results in their revision and cancellation, and as a result, undermines stability of the legislation [29] .opinion of the author, interpretation of the Constitution and laws of Ukraine should be carried out by the Constitutional Court of Ukraine. Authorizing a certain model of behavior the Supreme Rada of Ukraine may define the essence of such a rule. Nevertheless, the Parliament can not solve objectively the problem of conformity of the specified rule to the Constitution, as in these cases it is compelled to supervise its own activity..V. Teslenko carries out one more classification of functions of the Constitutional Court of Ukraine: 1) social fun...
