The purpose of the research is to reveal the relationship between legal progress and the fundamental principles of law in the context of their implementation at different levels of the legal system. The importance of justice, freedom, equality and humanity as an instrument of legal progress is shown. It is proved that the fundamental principles of law act as the limits of the development of the legal system, and these limits ensure the legal and political progress of mankind. The methodological basis of the research is presented as comparative-legal and systematic analysis, formal-legal method, method of interpretation, hermeneutic method, as well as methods of analysis and synthesis. In the conclusions the authors state that legal progress depends on the extent to which the fundamental principles of law are presented and implemented in the actual legal order. The fundamental principles of law converge with each other. Thus, it can be said that it is precisely the interaction and synergy of principles that strengthens legal progress in a given society.

The article highlights the opportunities for the introduction of e-government in the institutional system of society on the basis of digital, information and communication technologies (on the example of Ukraine). It develops the concept of digitalization from the point of that information, knowledge and communication technologies constitute the system of social and legal infrastructure of society. It demonstrates that digital society forms the basis of the safety of modern globalized world, expressed in quality indicators of "e-government". It is proved that E-government in the legal system of the country involves: first, creating conditions for interaction between government and citizens through the use of modern information and communication technologies; secondly, the availability and openness of state registers; third, the introduction of e-democracy tools. It is determined that there is a steady tendency in the Ukrainian society to spread e-government tools in the legal sphere through the provision of administrative information services as well as the use of e-democracy technologies. It is also justified that potential of e-democracy technologies is strong enough to create conditions for e-government in legal sphere through technological and technical support of legal services, improving the level of computer iteracy of the population, increasing accessibility and openness of public information.
