The authors of the article explore the multi-functionality of administrative law. Administrative legislation should take into account social realities, recognize the usefulness of social order (when assessing the need for legislative changes or their stability) and transfer them to the level of justice (in terms of the adequacy of legal regulation). After the restoration of independence, administrative law in Latvia and Lithuania had to undergo a transformation of values, abandon the imposed Soviet ideological standards and master new standards of democracies. This strengthened social and legal values, enshrined and protected in the Constitutions of both countries and after accession to the EU, in accordance with the provisions of public administration, allowed by the Treaty on the Functioning of the European Union.The article notes that the formation of legislative policy and the creation of legislation usually based on the discretion of the culture of politicians. The authors of the article draw attention to the synergistic knowledge of social reality and the use of this knowledge when building administrative and legal regulation to the level of macro-social regulation.
