In short
The last chapter of Volume XI of the Joint Regulation opens the courthouse door. The Planning Board may appear before the Court of First Instance to seek revocation of a final determination or the stoppage of works or of a use, where the determination was obtained in violation of the laws or regulations, or where it was obtained lawfully but there is evidence of breach during its execution and operation. But the chapter does not stop there: it also allows a private person, natural or legal, holding a proprietary or personal interest that could be adversely affected, to bring an action of injunction, mandamus, declaratory judgment or any other appropriate action to seek revocation of a permit obtained with incorrect or false information, the stoppage of work begun without permits or in breach of its conditions, the stoppage of an unauthorised use, the modification or conservation of structures, and even the demolition of works built without a permit. There is a warning that decides strategy: filing in court alleging the same facts as an administrative complaint makes the agency lose jurisdiction over that complaint automatically.
What is it?
It is Chapter 11.8 of Joint Regulation No. 9473, "Proceedings before the Court of First Instance". It has two sections: one on the ordinary procedure for the Planning Board to go to court, and another on the extraordinary remedies that may be brought by the Board, the government entities concerned, autonomous municipalities with hierarchy I to III, and private persons with a proprietary or personal interest.
Who can do it?
The extraordinary remedies in this chapter may be brought by the Planning Board, any government entity concerned or an autonomous municipality with hierarchy I to III, in representation of the public interest; and also by a private person, natural or legal, holding a proprietary or personal interest that could be adversely affected. That last phrase is what opens the forum to a neighbour. In addition, the Board itself may appear before the Court of First Instance to seek revocation of a final determination or the stoppage of works or a use in the two situations set out in Section 11.8.1.1.

Step by step
Step 1: When it is the Board that goes to court
The Board may appear before the Court of First Instance to seek revocation of a final determination or the stoppage of construction work or of a use in two situations. The first: where, after the corresponding administrative investigation, it learns that the final determination was obtained in violation of the applicable laws or regulations. The second: where the final determination was obtained lawfully, but there is evidence of a breach of laws and regulations during its execution and operation. That is: the permit can be attacked for how it was obtained or for how it is being used.
Step 2: Who else may go
The regulation expressly widens standing. The extraordinary remedies may be brought by the Board, any government entity concerned or an autonomous municipality with hierarchy I to III, in representation of the public interest; and also by a private person, natural or legal, holding a proprietary or personal interest that could be adversely affected. If you are the abutting neighbour of works affecting you, that is the phrase that opens the courthouse door.
Step 3: What may be asked for
The petition may be an action of injunction, mandamus, declaratory judgment or any other appropriate action, and it serves seven purposes. Revocation of a permit granted where the application was made using incorrect or false information. Stoppage of work begun without the corresponding authorisations and permits, or breaching the provisions and conditions of the permit granted. Stoppage of an unauthorised use. Modification of structures. Conservation of structures. Demolition of works built. And that the preventive or control measures necessary to achieve the purposes of Ley 161-2009, the regulations adopted under it and any other applicable law or regulation be taken.
Step 4: Demolition and its double requirement
The demolition item is carefully drafted and worth reading slowly. Demolition may be sought of works built which, at the time the petition is filed and at the time it is adjudicated, hold no construction permit, whether because one was never obtained or because it has been revoked, as provided by Article 14.1 of Ley 161-2009, and without using the complaint mechanism described in this Volume. That is two moments, not one: no permit when filing and no permit when adjudicating. If the owner legalises the works while the case is pending, that item no longer stands.
Step 5: The warning that decides strategy
This is the chapter’s most important sentence. It warns that filing the case under Article 14.1 of Ley 161-2009, alleging the same facts presented in an administrative complaint before the Board, the government entity concerned or the hierarchy I-III autonomous municipality, will cause the administrative agency to lose jurisdiction over the complaint automatically, and any action it takes on that complaint will be considered ultra vires. In plain terms: you cannot have both proceedings alive on the same facts. If you file in court, you kill your complaint; and if the agency carries on afterwards, its actions are void for want of power. Choose one road before filing, not after.
Step 6: Ten days for the hearing, twenty for judgment
The chapter puts a clock on the court, and it is a short one. The Court of First Instance must hold a hearing within a term no longer than ten calendar days from the filing of the petition, and must render judgment within a term no longer than twenty calendar days from the hearing. That contrast explains why this route exists: against administrative terms of fifteen, thirty and ninety days, here the case is litigated in weeks.
Step 7: And the orders you already received
It is worth not confusing forums. Final resolutions issuing provisional orders, orders to do or not to do and cease-and-desist orders under Articles 11(8) and (9) of Ley No. 75 are also reviewed at the Court of First Instance — San Juan Part or the part whose jurisdiction covers the place where the project is located — and they remain in full force and effect until the court makes another determination. That is a rule of Chapter 11.7, and it is different from this chapter’s extraordinary remedies: one reviews an order already issued to you, the other starts a lawsuit.
Where to do it
At the Court of First Instance. The chapter fixes no particular part for the extraordinary remedies of Section 11.8.1.2; Chapter 11.7 does fix one for the review of provisional orders, orders to do or not to do and cease-and-desist orders under Articles 11(8) and (9) of Ley No. 75, which go to the San Juan Part or the part whose jurisdiction covers the place where the project is located. As with any court action, it is worth consulting a lawyer before filing, above all because of the effect filing has on a pending administrative complaint.
How long it takes
What to do if something goes wrong
First of all, choose the road. The regulation warns that filing in court under Article 14.1 of Ley 161-2009 alleging the same facts as an administrative complaint causes the agency to lose jurisdiction over that complaint automatically, and that any later action it takes on it will be ultra vires. They are not two parallel roads: they are alternatives. If you choose court, look at what you can ask for: revocation of a permit obtained with incorrect or false information, stoppage of work begun without permits or in breach of its conditions, stoppage of an unauthorised use, modification or conservation of structures, demolition, and the necessary preventive or control measures. For demolition, bear the double requirement in mind: the works must be without a construction permit both when the petition is filed and when it is adjudicated. If you are a private person, your standing depends on holding a proprietary or personal interest that could be adversely affected. And reckon on the pace: the court must hold a hearing within ten calendar days of filing and render judgment within twenty calendar days of the hearing. Three caveats. First: we publish no cost, because Chapter 11.8 fixes no fee and court fees live in the Judiciary’s own schedule, not here. Second: we publish no total timeframe, because the chapter fixes the court’s terms for the hearing and judgment, not the case’s duration. Third: this guide explains what the regulation allows, not how to draft or litigate an injunction, mandamus or declaratory judgment; that needs a lawyer. And the file the Board links is named "Reglamento Conjunto de Emergencia", but the document inside is Joint Regulation No. 9473 of 16 June 2023.
Common mistakes
- Filing in court without knowing it kills the administrative complaint on the same facts.
- Expecting the agency to keep processing the complaint after filing: its actions would be ultra vires.
- Seeking demolition where the works obtained a permit before the petition is adjudicated.
- Filing without a proprietary or personal interest that could be adversely affected.
- Taking to the Court of Appeals a cease-and-desist order under Articles 11(8) and (9) of Ley No. 75.
- Assuming the order lapses because you filed: it remains in full force and effect until the court decides otherwise.
- Counting on fees in the regulation: the chapter fixes none.
Frequently asked questions
Can I, as a neighbour, go to court over illegal works?
The regulation contemplates it: besides the Board, the government entities concerned and hierarchy I-III autonomous municipalities, the petition may also be brought by a private person, natural or legal, holding a proprietary or personal interest that could be adversely affected.
Can I have the complaint and the lawsuit at the same time?
Not on the same facts. The regulation warns that filing the case under Article 14.1 of Ley 161-2009 alleging the same facts as an administrative complaint will cause the agency to lose jurisdiction over the complaint automatically, and any action it takes on it will be considered ultra vires.
Can demolition of unpermitted works be sought?
Yes, on a double condition: that the works built hold no construction permit at the time the petition is filed and at the time it is adjudicated, whether because one was never obtained or because it was revoked, under Article 14.1 of Ley 161-2009.
How long does the court take?
The chapter says the Court of First Instance must hold a hearing within a term no longer than ten calendar days from the filing of the petition, and must render judgment within a term no longer than twenty calendar days from the hearing.
When does the Board itself go to court?
Where, after the corresponding administrative investigation, it learns that the final determination was obtained in violation of the applicable laws or regulations; or where the final determination was obtained lawfully but there is evidence of a breach of laws and regulations during its execution and operation.
