International Covenant on Civil and Political Rights of 16 December 1996 (Journal of Laws 1977 No. 38, item 167) (ICCPR)
Article 2 – Each State Party to the present Covenant undertakes to respect and to ensure to all individuals within its territory and subject to its jurisdiction the rights recognised in the present Covenant, without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status.
Article 3 – The States Parties to the present Covenant undertake to ensure the equal right of men and women to the enjoyment of all civil and political rights set forth in the present Covenant.
The International Covenant on Civil and Political Rights is one of the most important acts of international law discussing basic human rights. Already at the beginning of the provisions concerning, among others, inherent right to life, liberty, security of person, it was indicated that all States Parties to the Covenant shall guarantee such rights to all persons regardless of any features or differences. Furthermore, each State Party undertakes to adopt appropriate measures aiming at adoption of appropriate legislation that:
a) ensures an effective remedy to any person whose rights or freedoms as recognised in the Covenant have been violated, notwithstanding that the violation has been committed by persons acting in an official capacity;
b) ensures that the right of every person claiming such a remedy shall be determined by competent judicial, administrative or legislative authorities, or by any other competent authority provided for by the legal system of the State, and develops the possibilities of judicial remedy;
c) ensures enforcing remedies when granted by the competent authorities.
