The Balance between the Theory and Legal Regulation of Nationality Issues in International and National Court Practices

The article considers the influence of international and national court practices on legal relations concerning the acquisition of nationality. A contemporary doctrine, to a greater extent, deals with the issues of either material comprehension of normative (regulatory) provisions on this issue or separate procedural peculiarities. However, an integrated approach that addresses domestic and international law rules, as well as the jurisprudence and case law at the inter-state and domestic levels, allows the widest possible coverage of the legal regulation of the subject matter in question and identifies the problems of normative regulation and determines the ways to improve it. Thus, the 'close connection' test and discretion (margin of appreciation) developed by international judicial institutions to decide issues concerning nationality are gradually becoming a part of the Russian Federation jurisprudence, as manifested in recent court cases. This taxonomy should be the case when concrete proposals are made for the creation or transformation of existing normative regulation The very life, social relations that exist must determine further development of law. In this case, it does not matter what form it takes: court precedents, doctrinal research, analysis of citizens' applications, etc.
