The constitutional complaint is a means to protect constitutional rights, as well as being the core element of a state governed by the rule of law. It was introduced into the Latvian legal system only in 2001, which is five years after the establishment of the Constitutional Court. A constitutional complaint is of great importance since not only does it protect fundamental human rights, but also guarantees the public interest. Although the Baltic States share many historical, social, formal and political similarities, there are many differences in the precise legal solutions and institutions. Thus, the possibility of filing a Constitutional complaint is recognised only in the Latvian legal system. While in Estonia a person has a limited direct access to the Supreme Court and Lithuania is merely considering its introduction.
