Is it worthwhile to file an administrative appeal if one year has already passed since the signing of the notoriety deed?

The Law of Common Administrative Procedure (Law 39/2025, of October 1st), establishes in its art. 21 that "The administration is obliged to issue an express resolution and to notify it in all procedures regardless of the way in which they are initiated". This article determines the right of the administered to demand from the administration an answer to our claims, in itself to demand the express resolution is not a resource, it is a request for the administration to answer and issue a resolution to be able to exercise the effective protection, that is, our rights, depending on the sense of the resolution.
