Law 39/2015
Article 32. Extension.
"1. The Administration, unless prescribed otherwise, may ex officio or at the request of the interested parties grant an extension of the established terms that does not exceed half of them, if the circumstances so advise and third party rights are not thereby prejudiced. The extension agreement must be notified to the interested parties.
[...]
3. Both the request of the interested parties and the decision on the extension must occur, in any case, before the expiration of the term in question. In no case can an already expired term be subject to extension. Agreements on extension of terms or on their denial are not subject to appeal, without prejudice to the proceeding against the resolution that puts an end to the procedure.
4. When a technical incident has made the normal operation of the system or the corresponding application impossible, and until the problem is solved, the Administration can determine an extension of the unexpired terms, and must publish on its electronic headquarters both the technical incidence that has become the concrete extension of the unexpired term."
