The thesis first deals with the current state of legal regulation of procedural time limits for filing lawsuits against the decision of the administrative body, for protection against inactivity of the administrative body and for protection against illegal intervention, instruction or coercion of the administrative body. The issue of measures of a general nature is left aside, as they are too close to a review of legislation.
The author concludes that although the issue of time limit is one of the key obstacles in examining the (im) possibility of introducing a single administrative action, it is not the only problem and therefore this question remains open. However, the current state of the legal deadlines de lege ferenda requires some improvements, in particular the possibility of waiving the missed deadline and introducing more permeability between different types of action by making the deadlines more standardized.
