The island institution has expressed its disagreement with the judicial decision, which it considers an attack on the social and economic development of Gran Canaria, as well as on the planning capacity of the cabildos. The Contentious-Administrative Chamber of the TSJC based the nullification of the PIO on the argument that the document was prepared to adapt to regulations that had already been repealed at the time of its final approval, referring to Law 4/2017 on Territorial Planning and Natural Spaces of the Canary Islands.

The Cabildo has categorically rejected this premise, arguing that the so-called Guidelines Law to which the court refers is not repealed. It has been maintained that the PIO retains its validity, as the thirty tourism guidelines and two rural land guidelines, along with other environmental, urban, and sectoral regulations, remain fully in force.

Furthermore, it has been pointed out that the Autonomous Administration itself provides for an "option right" to continue under previous legislation, and that in any case, only what contradicted Law 4/2017 would be suppressed, something that, according to the institution, does not occur in the PIO.

Given this situation, the Cabildo has announced that it will defend the Island Plan in all available legal instances. An appeal will be filed with the Supreme Court and a cassation appeal will be lodged with the TSJC itself. Additionally, the case will be taken to the Constitutional Court, and the feasibility of bringing the case before European Justice will be studied. This decision opens a new scenario for territorial planning on the island, with the island corporation firm in its stance to maintain the validity of the PIO.
