The 1997 Polish Constitution contains general anti-discrimination clauses, according to which all people shall be equal before the law and have the right to equal treatment by public authorities and no one shall be discriminated against in political, social or economic life for any reason whatsoever. This principle does not specify the criteria for the prohibited forms of discrimination.
Until 2010 Poland has transposed the equality directives mainly in the employment field. There were still a number of gaps, which finally caused some referrals to the European Court of Justice. The risk of loosing cases mobilized Polish Government to final approval of the “Act of on the Implementation of Certain Provisions of the European Union in the Field of Equal Treatment” that entered into force on January 1st, 2011 (henceforth as Act on Equal Treatment or AET).
