The urgency of the studied problem is due to the European integration of Ukraine and the presence in modern Ukrainian society of an acute need for codification of labour legislation. Ukraine has an extensive system of labour regulations that fail to correspond to one another and often lead to the violation of constitutional and human rights. This article aims to analyse the legislation of leading European countries in the field of codification of labour legislation in order to identify factors and problems of codification of labour legislation in Ukraine. Based on a comparative analysis of Ukrainian and European legislation in the field of codification of labour law, a list of recommendations will be presented aimed at improving the codification process of labour law in Ukraine. The materials of the article have practical value for everyone, who must participate in effective lawmaking in Ukraine.

The article bases and determines the principles of the formation of appropriate procedures for the provision of administrative services in the field of health care. The deductive methodology used ensures the formation of non-conflict statements on the principles built on European democratic values. The desirability of classifying these principles into three groups has been demonstrated according to the criterion of the limits of the formation of the fundamentals (principles) of regulation: general legal principles, regulatory principles of good governance. Improving existing legislation underpins the importance of considering the principle of legal certainty, which stipulates the need to avoid the priority of regulating procedures for the provision of administrative services in general and in the field of health, in particular through the use of statutes. It is concluded that the further development of e-government is proposed as one of the implementing directions of the European experience, as well as the experience of the United States and Great Britain in organizing the provision of administrative services in the field of health care.

This article explains the essence of the agent-based model method that simulates artificial societies to substantiate the thesis on its feasibility and scientific usefulness in lawmaking and law enforcement in Ukraine and research in the legal field. The primary research method used is synthesis, which allows combining components of a complex phenomenon and obtaining synthetic knowledge, which expands previous experience and constructs something new. Moreover, it allows going beyond the existing basis and drawing far-sighted conclusions, forecasting the directions of effective state formation and legal regulation in Ukraine.

The article investigates the lawfulness of the adoption and the consequences of the implementation of the Law of Ukraine "On State Financial Guarantees of Public Health Services". On the basis of the analysis of the norms of international law, the Constitution of Ukraine and the decisions of the Constitutional Court of Ukraine, the thesis about the unconstitutionality of this law is substantiated and the consequences of its implementation in the life of Ukrainian society are analyzed. The concepts of health care and medical services are compared. The negative consequences of the introduction of medical reform are analyzed. Proposed ways to solve the problem of passing laws that are unconstitutional and contradict the current legislation. Specific legal mechanisms of implementation of which will contribute to ensuring the constitutionality and legality of legislative activity are proposed. The main directions of violation of the Constitution of Ukraine of the introduced "medical reform", which was initiated by the Law of Ukraine "On State Financial Guarantees of Medical Services to the Population", have been identified. The thesis about the illegality and illegitimacy of this law is confirmed, justification of the unconstitutionality and contradiction of the provisions of this law is made by the decision of the Constitutional Court of Ukraine. The conclusion was made about the necessity of termination of this Law and other normative acts adopted on its basis.

The relevance of the issues outlined in the article is due to the peculiarities of the legislative regulation of the participation of representatives and other actors in the civil process of Ukraine. In this vein, the purpose of the article is to scientifically prove that procedural representation differs significantly from representation in civil law, among other things, in the object and nature of the relationship that exists between the representative and the principal, thus as well as the legal grounds and consequences of both processes. Furthermore, it is observed that the specialist, unlike the expert, acts as an assistant and consultant to the court and does not carry out an independent investigation aimed at clarifying the relevant circumstances of the case. The main method of research on this topic was modeling, which allowed, among other things, to consider the civil process as the only organizational lawsuit that serves to resolve the life situation. It is concluded that the legislative participation model of representatives and other people aims to improve their professional skills aimed at strengthening the work of the judiciary, while managing and resolving various conflicts of different nature to guarantee social order.
