The Lidl case of Via Palazzotto, Catania: res judicata as the law of the case

A reading of judgment No 13/2018 of the Sicilian Council of Administrative Justice, and a hypothesis of administrative-law significance whose verification rests exclusively with the judicial authorities. No administrative measure is examined or cited here.

The decision

Sicilian Council of Administrative Justice (C.G.A.R.S.), judgment of 16 January 2018, No 13, available on the Italian administrative justice portal.

Method first

The matter is known to the local press as the Lidl case of Via Palazzotto: that is the name the newspapers covering it have long used. On 28 July 2026, according to press reports, the Catania Public Prosecutor’s Office ordered the urgent preventive seizure of the supermarket building site, with the first entries in the register of suspects over alleged planning breaches concerning the designation of the area.

This note examines no administrative measures, reports no findings and attributes no conduct to anyone. It starts from a single document, judgment No 13 of 16 January 2018 of the Sicilian Council of Administrative Justice, and puts forward a hypothesis of administrative and procedural significance. Verifying the facts that hypothesis presupposes rests exclusively with the Catania Public Prosecutor’s Office and, within its jurisdiction, with the administrative courts. Whoever may be involved, in whatever capacity, enjoys the presumption of innocence guaranteed by Article 27(2) of the Italian Constitution.

What the final judgment established

By judgment No 13 of 2018 the C.G.A.R.S. closed the dispute over a plot on Via Palazzotto for which planning permission for a medium-sized food store had been sought in 2013, and refused by the Municipality on the basis of the plan designation as a secondary school and public green space.

The judgment requalified that designation as a substantially expropriatory constraint, lapsed after the five-year period. But from that lapse the Court derived no freedom to build. On the contrary, in its own words: the lapse of the constraint “returns the area to non-buildability, preventing new construction”, so that “the refusal of the permission sought is, as matters stand, correct” (paragraph 4.7). The only obligation placed on the Municipality was to fill the planning vacuum by rezoning the area “in the forms and with the guarantees provided by law” (paragraphs 4.7, 4.8 and 6). In all other respects the claim was dismissed, including the claim for damages.

The decisum thus rests on three propositions: no right to build was recognised; the refusal was held correct pending new planning; the performance due was the replanning of the area, in the forms and with the guarantees provided by law.

Res judicata is the law of the case

An administrative judgment that has become final is not merely the end of a dispute: it is the rule that thereafter governs the relationship between the parties and shapes any subsequent exercise of public power. The traditional formula, dear to scholarship and recurrent in the case law, is that a final judgment constitutes the law of the case: an authority that returns to decide upon the same matter does not start afresh, but within the perimeter the court has drawn.

Here that perimeter is clear. A rezoning judgment obliges the authority to replan, but does not of itself confer the right to build: so held, among others, the Council of State in judgments No 9482/2022 and No 6951/2023, and in the Sicilian case law the Palermo Regional Administrative Court in judgment No 1091/2024. The choice of the area’s new designation belongs to the planning function, which has its own seat and form: the plan variant, with the competence of the City Council and the participatory guarantees the law attaches to it. And until replanning occurs, the area remains subject to the regime of so-called white zones (Article 9 of Presidential Decree No 380/2001 and Article 9(3) of Presidential Decree No 327/2001): a level of buildability so reduced as to be structurally incompatible with a new medium-sized retail store.

The hypothesis

Here lies the working hypothesis, and it must be stated plainly that a hypothesis is all it is: if no plan variant intervened between the 2018 final judgment and the building permit from which the site works arose, the building title would have been issued for an area the judgment had declared non-buildable as matters stood, and in respect of which the only act due was replanning.

If that were so, one point would be certain: the final judgment, which is the law of the case, would stand violated. And the consequences, in administrative and procedural terms, would be systemic. A measure adopted in breach or circumvention of a final judgment is null and void under Article 21-septies of Law No 241/1990: not merely voidable, void. That nullity is enforced before the compliance court, in the proceedings governed by Articles 112 et seq. of the Code of Administrative Procedure (Article 114(4)(b)), with powers extending to the appointment of an ad acta commissioner to carry out the performance left undone. And in the meantime the white-zone regime, which no individual permit can override, would remain intact.

The converse hypothesis deserves equal intellectual honesty: if a variant did intervene, in the forms and with the guarantees the judgment itself recalls, the picture would change radically, for the judgment would stand executed and the area’s new designation would be the legitimate product of the planning function. Which of the two hypotheses matches the facts is not a question this note can, or seeks to, resolve.

Who verifies, and how

Whether or not a variant exists, and the regularity of the sequence that led to the building title, are matters of fact: and facts are established in the proper fora. On the criminal side, verification is under way at the Catania Public Prosecutor’s Office; on the administrative side, the matter would fall, if seised, to the administrative courts, whether in compliance or in ordinary review proceedings. A preventive seizure is a precautionary measure, not a finding of liability: until a final conviction every person involved is presumed innocent, and every reconstruction, including the one hypothesised here, remains precisely that, a hypothesis.

Why the case matters

However it ends, the Via Palazzotto affair raises a question larger than any single building site: the effectiveness of administrative res judicata. A legal order in which a final judgment can be overtaken in fact, without passing through the forms the law prescribes, is one in which neither citizen nor business can rely on the word of the courts. That holds for those bound by a judgment, and for those protected by it. An administrative judgment lives through its execution: that is what is at stake, and that is why the outcome of the pending verifications concerns anyone dealing with planning law and administrative justice.
