Abstract
The article analyzes the principle of legal certainty, the constitutional presumption of knowledge of the Constitution of the Republic of Kazakhstan and laws, and the obligation to comply with them. The contribution of constitutional law scholars to the development of the constitutional theory is emphasized. The author studies the political, legal, and social essence of the Constitution of the Republic of Kazakhstan as a kind of legal and cultural phenomenon that determines the development of Kazakhstan's society and state after independence. The full constitutional and legal characteristics of the sovereignty of the Republic of Kazakhstan and the significance of the Constitution in its strengthening and development are given. As criteria of constitutional law called the supremacy and direct action of the Constitution; effective work of state bodies in order to create favorable conditions for the development of society and the rights and freedoms of citizens and their associations, the performance of their legal responsibilities; ensure the inevitability of bringing perpetrators to legal liability. Attention is drawn to the fact that the principle of the supremacy of the Constitution, which ensures constitutional law and order, can be understood in two aspects: material and formal; their content is revealed. It is concluded that even the ideal text of the Constitution cannot guarantee its supremacy without its implementation in the constitutional legal order. The author substantiates the conclusion that the constitutional law and order presupposes the stability of the Constitution and the inadmissibility of its frequent amendments that are not objectively necessary.
