This article explores the interrelation between constitutional and judicial argumentation, and the key transformation models of normative legal regulation under the influence of constitutional and judicial decisions. Using the analysis and summarization of the extensive constitutional and judicial practice, the author describes the argumentative patterns emerging as a result of appeal of the constitutional justice bodies to particular variants of normative correction. Special attention is given to such corrective measures as disqualification of the legal norm, formulation of an exception to the general rule, modification of the hypothesis and disposition of the legal norm, correction of its sanction, clarification of the mechanism of action of the legal norm in time, space and scope of persons, filling of the legislative gaps, and securing additional guarantees. The novelty of this research consists in studying the constitutional and judicial argumentation from instrumental perspective, namely in the context of its of carrying out of its official function with regards to constitutional control, which allowed outlining the argumentative patterns that are prevalent within the constitutional discourse, and thus grasp the mechanism of generation of arguments. The acquired results demonstrate that conceptually, the reasoning of the constitutional justice bodies reflect the process of critical re-evaluation of the current legal regulation and determination of its constitutional flaws with simultaneous projection of the normative model that fits into the constitutional framework. The conclusion is formulated that the constitutional and judicial argumentation aims to indicate the most acceptable variant of regulation from the constitutional perspective, outline the eligible lawmaking divergence from the constitutional standards legal regulation, as well as explain which part of the normative legal regulation should be corrected based on the constitutional requirements.
