Abstract
The issue of the nature of the catalogue laid down in § 2.1 of the regulation of the Minister of Finance dated 13 April 2006 concerning information which may be potentially harmful to the legitimate interests of the issuer and how the issuer should proceed in connection with a delay as regards public disclosure of inside information arouses disputes in the doctrine. There are opinions for both the open and closed nature of such catalogue. So far there were no court ruling in this matter. That is why the glossed ruling is of vital importance both for the doctrine as well as the practice of transactions. The ruling of the Voivodship Administrative Court as to the open nature of the catalogue as well as the underlying reasoning should be considered as correct.
