The text covers issues related to determining the amount of the general pension in relation to persons who received an early pension before obtaining this pension. The basis for the considerations is the judgment of the Constitutional Tribunal issued in case SK 140/20, in which it was found unconstitutional Article 25 section 1b of the Act on Pensions and Annuities from the Social Insurance Fund, in the scope in which it provided a basis for reducing the basis of the general pension by the amounts previously paid to the pensioner from early pensions. The argumentation contained in the justification of the Constitutional Tribunal was assessed, indicating its limited scope of impact, imposed by the boundaries of the case, which was derived as a result of the constitutional complaint, limiting the possibility of its application to persons who applied for their early pensions before 6 June 2012 and were then surprised - while receiving an early pension - by the content of the introduced Article 25 section 1b of the Act on Pensions and Annuities from the Social Insurance Fund. The article assesses the legal consequences of the aforementioned judgment of the Constitutional Tribunal, both in terms of the legal basis for initiating administrative proceedings before pension authorities in matters of re determining the amount of an incorrectly calculated pension, and in the phase of review of a pension decision by a common court.
