Any natural person should have equal opportunities to file applications before the European Court of Human Rights (ECtHR). This right constitutes a fundamental part of the system of human rights protection in Europe. However, when considering previous jurisprudence of the ECtHR, the existence of barriers for certain groups is obvious. The reason for this lies in the Courts restrictive interpretation of provisions on locus standi, or rather representation. People with disabilities are particularly affected by this practice. On 17 July 2014 the European Court of Human Rights passed a judgement with the potential to break down the barriers to the access to the Courts justice for people with disabilities. The judgement Câmpeanu clearly stands out against previous ECtHR jurisprudence due to its innovative content. Despite several shortcomings regarding the criteria of locus standi, a NGO, dealing on behalf of the deceased victim, has been able to validly file an application.This thesis discusses the current approach of the European Court of Human Rights in the case Câmpeanu as well as in similar cases, and further provides a profound analysis of the topic. In the course of this analysis, the central innovative content of the judgement in Centre for Legal Resources on behalf of Valentin Câmpeanu v. Romania, regarding provisions of the European Convention on Human Rights on locus standi, is going to be explained. In this context, the concept of de facto representation is particularly examined. Furthermore, the effects of the Câmpeanu judgement and perspectives on future developments are discussed.
