The article deals with the role of the European Court of Human Rights (ECtHR) in protecting the right to social security. There is the analysis of the case law of the ECtHR on the violation of the right to social security, namely the right to receive a pension, which the ECtHR classifies as property rights. The authors have outlined the ways to improve the practice of the ECtHR in this area in modern national and world socio-economic conditions. According to available estimates, around 50 per cent of the global population has access to some form of social security, while only 20 per cent enjoy adequate social security coverage. Ensuring an ap-propriate mechanism for the protection of human and civil rights is a priority for every country. However, according to case law, the number of complaints of violations or non-recognition of their rights is growing every year. An important role in the protection of human rights in today's conditions is played by an international judicial body - the European Court of Human Rights. In Ukraine, where socio-economic rights are recognized at the constitutional level, their guarantee content in the current laws is still not clearly defined, and therefore, as evidenced by the practice of the Constitutional Court of Ukraine, legal mechanisms their protection, in particular the means of judicial control remain ineffective. The right to social security is the right to access and retention of benefits, both in cash and in kind, without discrimination in order to protect, in particular, against (a) lack of income from work caused by illness, disability, maternity, occupational injuries , unemployment, old age or death of a family member; (b) inaccessible access to medical care; (c) insufficient family support, especially for children and adult dependents. It is well known that the European Convention does not contain many socio-economic rights as such (with a few exceptions - protection of property and the right to education). Thus , the former president of the ECtHR Jean-Paul Costa specifically pointed to another important European human rights treaty – the European Social Charter. Human rights are a universal value, and their protection is the task of every state. The European Court of Human Rights plays an important role in protecting human rights in modern conditions. The functioning of such an international judicial institution can not only solve a problem of protection of violated rights, but also affect the development of the judicial system of each state. The main principle of realization and judicial protection of social rights is non-discrimination on the grounds of sex, age, race, national and social origin of the individual, and the role of auxiliary institutions of the Council of Europe in generalizing and improving the ECtHR’s activity has been emphasized.
