ORDER
in the proceedings regarding the constitutional legitimacy of Art. 1, paragraphs 2, 5, 7 and 8, and Art. 3, as well as Annexes A, B, C, D and E of Sardinia Regional Law no. 20 of December 5, 2024, entitled "Urgent measures for the identification of suitable and unsuitable areas and surfaces for the installation and promotion of plants using renewable energy sources (RES) and for the simplification of authorization procedures," brought by the Regional Administrative Court for Lazio, Third Section, by orders dated May 13 and 26, 2025, and June 12, 2025, registered respectively under numbers 148, 154 and 155 of the 2025 Register of Orders; as well as Art. 1, paragraphs 1 (with specific reference to letter a), 2, 5, 6 and 7, as well as Annexes A, B, C, D, E and G of the aforementioned Sardinia Regional Law no. 20 of 2024, brought by the Regional Administrative Court for Sardinia, First and Second Sections, by orders dated June 9 and 26, 2025, and December 12, 2025, registered respectively under numbers 131, 159, 160, 161 and 263 of the 2025 Register of Orders and published in the Official Gazette of the Republic, First Special Series, numbers 28, 36 and 37 of the year 2025 and no. 3 of the year 2026.
Having seen the statements of appearance of RWE Renewables Italia srl, Sorgenia Renewables srl, Maple Tree Solar srl, Green Sole Renewables Italia 1 srl, EF Agri società agricola a rl, Edison rinnovabili spa, and the Autonomous Region of Sardinia;
having heard Judge Angelo Buscema as Reporting Judge at the public hearing of May 5, 2026;
having heard counsel Carlo Comandè for Maple Tree Solar srl and Edison rinnovabili spa, Simone Abellonio for RWE Renewables Italia srl, Massimo Colicchia for Sorgenia Renewables srl, Germana Cassar for Green Sole Renewables Italia 1 srl, Andrea Sticchi Damiani for EF Agri società agricola a rl, as well as Giovanni Parisi and Floriana Isola for the Autonomous Region of Sardinia;
having deliberated in the chambers on May 5, 2026.
Considering that, in three orders of similar content, registered respectively as nos. 148, 154 and 155 of the 2025 Register of Orders, the Regional Administrative Court for Lazio, Third Section, raised questions of constitutional legitimacy regarding Art. 1, paragraphs 2, 5, 7 and 8, and Art. 3, as well as Annexes A, B, C, D and E of Sardinia Regional Law no. 20 of December 5, 2024, entitled "Urgent measures for the identification of suitable and unsuitable areas and surfaces for the installation and promotion of plants using renewable energy sources (RES) and for the simplification of authorization procedures," in reference to Articles 3, 9, 41, 97, 11 and 117, first paragraph, in relation to the principles expressed by Directive (EU) 2018/2001 of the European Parliament and of the Council of December 11, 2018, on the promotion of the use of energy from renewable sources, and by Regulation (EU) 2018/1999 of December 11, 2018, on the Governance of the Energy Union and Climate Action, amending Directives (EC) No. 663/2009 and (EC) No. 715/2009 of the European Parliament and of the Council, Directives 94/22/EC, 98/70/EC, 2009/31/EC, 2009/73/EC, 2010/31/EU, 2012/27/EU and 2013/30/EU of the European Parliament and of the Council, Council Directives 2009/119/EC and (EU) 2015/652 and repealing Regulation (EU) No. 525/2013 of the European Parliament and of the Council, by Directive (EU) 2023/2413 of the European Parliament and of the Council of October 18, 2023, amending Directive (EU) 2018/2001, Regulation (EU) 2018/1999 and Directive 98/70/EC as regards the promotion of energy from renewable sources, and repealing Council Directive (EU) 2015/652, and by Regulation (EU) 2021/1119 of the European Parliament and of the Council of June 30, 2021, establishing the framework for achieving climate neutrality and amending Regulation (EC) No. 401/2009 and Regulation (EU) 2018/1999 ("European Climate Law”), second paragraph, letters m) and s), and third paragraph of the Constitution, to Art. 10 of Constitutional Law no. 3 of October 18, 2001 (Amendments to Title V of Part II of the Constitution), as well as to Articles 3 and 4 of Constitutional Law no. 3 of February 26, 1948 (Special Statute for Sardinia);
that the referring courts challenge the aforementioned provisions of Sardinia Regional Law no. 20 of 2024 insofar as they provide that the classification of an area as "unsuitable" corresponds to a prohibition on installing RES plants, as well as where they provide that such prohibition applies also to proceedings already authorized, provided that the commencement of works has not caused an irreversible alteration of the state of the places, and where they establish that, in the event of an overlap of a plant on a suitable and an unsuitable area, the prohibition on installation shall prevail;
that, regarding relevance, the Lazio Regional Administrative Court asserts that it was seized by the companies RWE Renewables Italia srl, Sorgenia Renewables srl and Green Sole Renewables Italia 1 srl, which operate in the renewable energy sector and hold permits for RES plant projects located, inter alia, in the territory of the Autonomous Region of Sardinia in areas classified by the aforementioned Sardinia Regional Law no. 20 of 2024 as unsuitable, resulting in the ineffectiveness of the authorizations already granted;
that, as regards non-manifest groundlessness, the referring courts complain, first and foremost, of a violation of the State's concurrent legislative competence, as the regional regulation, by establishing an absolute prohibition on the installation of RES plants in areas classified as unsuitable, would conflict with the fundamental principles established by the State in the matter of "national production, transport and distribution of energy," referred to in Art. 117, third paragraph of the Constitution; more precisely, the Sardinian regional law would conflict with the principle of maximum diffusion of renewable energy, transforming the "unsuitable area" from a relative concept (the location of an administrative burden) into an absolute concept (the location of a statutory prohibition on building), thereby precluding any concrete assessment of the interests involved;
that the challenged provisions would also violate Articles 11 and 117, first paragraph of the Constitution, in relation to obligations deriving from the EU legal order. In particular, Directive 2018/2001/EU and Regulation 2018/1999/EU are cited, both as amended by Directive (EU) 2023/2413 of the European Parliament and of the Council of October 18, 2023, and by Regulation 2021/1119/EU. By excluding approximately 99 percent of the territory from the location of plants, it would be effectively impossible to achieve the decarbonization and minimum installed capacity targets (equal to 6.2 GW for the Autonomous Region of Sardinia) agreed upon at the European and national levels, thereby harming the interest in climate protection as an integral part of environmental protection (and, thus, also violating Art. 9 of the Constitution);
that the courts *a quibus* further complain of an unreasonable compression of the freedom of economic initiative (Art. 41 of the Constitution), because the introduction of generalized prohibitions, not supported by a specific and detailed technical investigation for every single area, but deriving from abstract and overarching classifications, would constitute a limit on the economic activity of the proponents that would not be justified by a real need for social utility or the protection of overriding values, proving disproportionate to the pursued objective;
that the challenged regional legislation would also be devoid of intrinsic reasonableness, as it would establish criteria for unsuitability so broad as to be contradictory to the goal of ecological transition, while also excluding the administrative procedure reserve, or the possibility for the administration to weigh, on a case-by-case basis, the interest in energy production against that of landscape protection, replacing it with a rigid legislative assessment;
that the principles of impartiality and good performance of public administration referred to in Art. 97 of the Constitution would also be violated, because the challenged legislation would impact proceedings already finalized;
that the referring courts also deduce a violation of Art. 117, second paragraph, letters m) and s) of the Constitution, in relation to what is established by Legislative Decree no. 199 of November 8, 2021, entitled "Implementation of Directive (EU) 2018/2001 of the European Parliament and of the Council of December 11, 2018, on the promotion of the use of energy from renewable sources, as amended by Directive (EU) 2023/2413 of the European Parliament and of the Council of October 18, 2023, amending Directive (EU) 2018/2001, Regulation (EU) 2018/1999 and Directive 98/70/EC as regards the promotion of energy from renewable sources, and repealing Council Directive (EU) 2015/652," which authorizes the regions to identify suitable areas by law. The challenged regional legislation, in fact, went so far as to define zones of absolute unsuitability, invading the exclusive legislative competence of the State in the matters of "determination of the essential levels of services concerning civil and social rights" and "protection of the environment, the ecosystem and cultural heritage";
that the Autonomous Region of Sardinia, a party to the main proceedings, entered an appearance in all three cases, requesting that the questions of constitutional legitimacy raised by the Lazio Regional Administrative Court be declared inadmissible and, in any case, unfounded;
that, regarding the inadmissibility of the questions, the referral orders allegedly failed to adequately justify the necessity of applying the challenged provisions in the proceedings *a quibus*;
that, on the merits, the challenged legislation would constitute a legitimate exercise of regional legislative competence in the matters of "building and urban planning" and "production and distribution of electrical energy" (respectively, Art. 3, letter f, and Art. 4, letter e, of the Special Statute);
that, according to the regional defense, the identification of unsuitable areas is an expression of the power of territorial governance, aimed at preserving the integrity of the Sardinian landscape and the agricultural vocation of the soil from disorganized and massive development of RES plants;
that in the case registered as no. 154 of the 2025 Register of Orders, Sorgenia Renewables Italia 1 srl intervened, also filing a subsequent brief and requesting that Art. 1, paragraphs 2, 5, 7 and 8, and Art. 3 of Sardinia Regional Law no. 20 of 2024 be declared constitutionally illegitimate;
that in the case registered as no. 155 of the 2025 Register of Orders, Green Sole Renewables Italia 1 srl intervened, also filing a subsequent brief and requesting that the constitutional illegitimacy of Art. 1, paragraphs 2, 5, 7 and 8, and Art. 3, as well as the related Annexes A, B, C, D and E of Sardinia Regional Law no. 20 of 2024 be declared;
that, in five orders of similar content, registered respectively as nos. 131, 159, 160, 161 and 263 of the 2025 Register of Orders, the Sardinia Regional Administrative Court, First and Second Sections, raised questions of constitutional legitimacy regarding Art. 1, paragraphs 1 (including letter a), 2, 5, 6 and 7, as well as Annexes A, B, C, D, E and G of Sardinia Regional Law no. 20 of 2024, in reference, overall, to Articles 3, 9, 41, 97, 11 and 117, first paragraph, in relation to the principles expressed by Directive 2018/2001/EU, as amended by Directive 2023/2143/EU, and third paragraph, of the Constitution, as well as Articles 3 and 4 of the Special Statute;
that, regarding relevance, the referring judges report having been seized of appeals filed by the companies Maple Tree Solar a rl (Reg. Ord. no. 131 of 2025), EF Agri società agricola a rl (Reg. Ord. nos. 159, 160 and 161 of 2025), and Edison rinnovabili spa (Reg. Ord. no. 263 of 2025) for the annulment of the suspension orders for construction works on photovoltaic plants, as well as for the inadmissibility of applications for environmental impact assessment verification for agri-voltaic plants. Such measures would be based on the entry into force of Sardinia Regional Law no. 20 of 2024, which would have included the areas affected by the interventions as "unsuitable" for the installation of plants from renewable energy sources, ordering the immediate cessation of all investigative or implementation activities;
that the challenged provisions would constitute the exclusive legal basis for the contested measures: Art. 1, paragraph 1 (including letter a), defines the criteria for the unsuitability of areas that preclude intervention, while paragraph 5 extends the effectiveness of such prohibitions to pending proceedings and works not yet completed;
that, regarding non-manifest groundlessness, the regional legislation, by identifying unsuitable areas through rigid and generalized criteria, would conflict with the fundamental principles regarding the "national production, transport and distribution of energy," referred to in Art. 117, third paragraph of the Constitution. In particular, the regional legislation would conflict with Art. 20 of Legislative Decree no. 199 of 2021, which prohibits regions from suspending the terms of proceedings pending the definition of suitable areas;
that the challenged provisions would conflict with the fundamental principles, established by Legislative Decree no. 199 of 2021 and by the Decree of the Minister of the Environment and Energy Security, adopted in concert with the Minister of Culture on June 21, 2024 (Regulation for the identification of suitable surfaces and areas for the installation of plants using renewable sources), in the matter of "national production, transport and distribution of energy" (Art. 117, third paragraph of the Constitution), since the identification of unsuitable areas by regional law could not translate into an *a priori* and generalized prohibition, but should follow from an adequate investigation within an administrative procedure;
that the regional regulation would hinder the achievement of the binding decarbonization and renewable energy production targets set by the European Union (Directive 2018/2001/EU), negatively affecting the commitments undertaken by the Italian State, thus also violating Articles 11 and 117, first paragraph of the Constitution;
that Art. 1, paragraph 5, of Sardinia Regional Law no. 20 of 2024 is likewise challenged, insofar as it overrides the legitimate expectations of private parties who have already obtained authorization titles or initiated significant investments, with an unreasonable effect and, therefore, detrimental to Art. 3 of the Constitution, as it would disproportionately sacrifice private initiative to a landscape protection carried out in the abstract and without a concrete balancing of opposing interests;
that the aforementioned regional legislation would also conflict with the principle referred to in Art. 9 of the Constitution, according to which the Republic protects the environment, biodiversity and ecosystems "also in the interest of future generations";
that, finally, the paralysis of administrative action is denounced, removed from the function of investigative assessment and bound by a legislative automatism that would prevent flexible and reasonable territorial management, resulting in a violation of Art. 97 of the Constitution;
that in all cases the Autonomous Region of Sardinia entered an appearance, being a party to the main proceedings, requesting that the questions of constitutional legitimacy be declared inadmissible and, in any case, unfounded;
that, regarding inadmissibility, the referring judges allegedly failed to provide an adequate description of the concrete case, nor did they dutifully attempt an interpretation of the challenged legislation in conformity with the Constitution;
that, on the merits, Sardinia Regional Law no. 20 of 2024 would be constitutionally legitimate because it was adopted in the exercise of regional statutory powers in the matters of "building and urban planning" and "production and distribution of electrical energy" (Art. 3, letter f, and Art. 4, letter e, of the Special Statute). The challenged regulation, moreover, would not aim to interdict the development of renewable energy, but to govern the structure of the regional territory, preventing indiscriminate land consumption and the compromise of areas of particular environmental and landscape value;
that the companies Maple Tree Solar srl (Reg. Ord. no. 131 of 2025), EF Agri società agricola a rl (Reg. Ord. nos. 159, 160 and 161 of 2025), and Edison rinnovabili spa (Reg. Ord. no. 263 of 2025) entered an appearance as petitioners in the main proceedings in support of the declaration of constitutional illegitimacy of the provisions challenged by the Sardinia Regional Administrative Court;
that at the public hearing of May 5, 2026, the Autonomous Region of Sardinia insisted on the inadmissibility of the questions, or the restitution of the documents to the referring judges, in light of this Court's judgment no. 184 of 2025.
Considering that the Lazio Regional Administrative Court, Third Section, and the Sardinia Regional Administrative Court, First and Second Sections, have doubts, with reference to Articles 3, 9, 41, 97, 11 and 117, first paragraph, in relation to the principles expressed by Directive 2018/2001/EU and Regulation 2018/1999/EU, as amended by Directive 2023/2413/EU and Regulation 2021/1119/EU, second paragraph, letters m) and s), and third paragraph, of the Constitution, Art. 10 of Constitutional Law no. 3 of 2001, as well as Articles 3 and 4 of the Statute of Autonomy, regarding the constitutional legitimacy of Art. 1, paragraphs 1 (in some cases with specific reference to letter a), 2, 5, 6, 7 and 8, and Art. 3, as well as Annexes A, B, C, D, E and G of Sardinia Regional Law no. 20 of 2024;
that the orders raise similar questions and, therefore, the cases must be joined;
that the referring judges, although challenging multiple provisions of Sardinia Regional Law no. 20 of 2024, as well as numerous Annexes, articulate distinct grounds of challenge concerning exclusively: Art. 1, paragraph 5, of Sardinia Regional Law no. 20 of 2024, i.e., the provision that provides for the prohibition of the installation of RES plants in areas defined as unsuitable by Annexes A, B, C, D and E (all referral orders); Art. 1, paragraph 7, of Sardinia Regional Law no. 20 of 2024, insofar as it provides that, in the case of a project overlapping suitable and unsuitable areas, the non-suitability criterion shall prevail (all orders); Art. 3 of Sardinia Regional Law no. 20 of 2024 (Reg. Ord. nos. 148, 154 and 155 of 2025) insofar as it introduces a standardized regional procedure for overcoming the classification of a place as unsuitable;
that only the order of the Sardinia Regional Administrative Court, Second Section (Reg. Ord. no. 131 of 2025), when justifying the challenge to Art. 1, paragraph 1, letter a), of Sardinia Regional Law no. 20 of 2024 – pursuant to which the regional law identifies suitable and unsuitable areas – contests its constitutional legitimacy, arguing that the regions would have the competence to determine only suitable areas and not also unsuitable ones;
that, with reference to the other provisions – specifically Art. 1, paragraphs 1, 2, 6 and 8, of Sardinia Regional Law no. 20 of 2024, as well as Annexes A, B, C, D, E and G – the manifest inadmissibility of the related questions must be declared, as they are not supported by an adequate motivational apparatus capable of articulating even the slightest ground for challenge;
that, subsequent to the referral orders, this Court, with judgment no. 184 of 2025, declared the constitutional illegitimacy, insofar as relevant here, of Art. 1, paragraph 2, first sentence, limited to the words ", or authorized that have not caused an irreversible alteration of the state of the places," 5, first, second, third and fourth sentences, 8, 9, and 3, paragraphs 1, 2, 4 and 5, of Sardinia Regional Law no. 20 of 2024;
that, with the same judgment, the question of constitutional legitimacy regarding Art. 1, paragraph 7, of Sardinia Regional Law no. 20 of 2024 was declared unfounded, in the terms set out in the reasoning;
that, with reference to Art. 1, paragraph 5, the aforementioned judgment affirmed that "in the new context of the fundamental principles of the matter, the power, provided for by Art. 20, paragraph 4, of Legislative Decree no. 199 of 2021, to identify suitable areas by regional law, was granted to the regions also with regard to unsuitable areas, with the clarification, however, that unsuitability can never equate to an absolute and *a priori* prohibition (judgment no. 134 of 2025)";
that, with reference to paragraph 7 of Art. 1 – pursuant to which, in the event that a project falls partly within suitable areas and partly within unsuitable areas, non-suitability prevails – judgment no. 184 of 2025 clarified that this provision must be understood as meaning that the circumstance whereby a renewable energy production plant also lies on an area declared unsuitable does not represent an absolute impediment to its realization, but rather the impossibility of accessing the simplified authorization procedure. In fact, pursuant to the aforementioned state legislation, the final decision regarding the realization of RES plants must be taken at the outcome of the individual authorization procedure concerning the specific plant project, and it is in that forum, therefore, that the requirements of maximum landscape protection and protected naturalistic areas that justify the non-simplified authorization procedure must be duly taken into account. This allows for an assessment of the relationship between the two areas in practice and for a complete balancing of nature protection and environmental protection through the reduction of polluting energy sources;
that, with the same judgment, the constitutional illegitimacy of Art. 3, paragraphs 1, 2, 4 and 5, of Sardinia Regional Law no. 20 of 2024 was also declared, noting that regional legislation cannot provide for a procedure for landscape authorization different from that dictated by state legislation, "because regions are not permitted to introduce derogations to state environmental protection institutions, which dictate uniform regulations valid throughout the national territory, within which landscape authorization must be included (ex multis, judgments no. 22 of 2025 and no. 160 of 2021)";
that, according to the consistent jurisprudence of this Court, "‘in the face of the occurrence of pronouncements of constitutional illegitimacy (order no. 26 of 2009), it is up to the referring judge to assess in practice the impact of the supervening changes both with regard to relevance and with reference to the non-manifest groundlessness of the raised questions of constitutional legitimacy (ex plurimis, orders no. 182 of 2019 and no. 154 of 2018)’ (order no. 49 of 2020)" (order no. 184 of 2020);
that, also subsequent to the filing of the referral orders and before the publication of judgment no. 184 of 2025, Sardinia Regional Law no. 31 of November 6, 2025, was approved, entitled "Amendments to Article 1 and to Annex G of Regional Law no. 20 of December 5, 2024 (Urgent measures for the identification of suitable and unsuitable areas and surfaces for the installation and promotion of plants using renewable energy sources (RES) and for the simplification of authorization procedures)," which, insofar as relevant, with Art. 1, paragraph 1, partially modified paragraph 7 of Art. 1 of Sardinia Regional Law no. 20 of 2024 (letter a) and added paragraph 7-bis (letter b);
that the verification of such supervening facts by the courts *a quibus* assumes a prejudicial relevance with respect to the examination of the grounds of constitutional illegitimacy deduced in the referral orders, which refer specifically, as seen, to the provisions declared constitutionally illegitimate by judgment no. 184 of 2025;
that, therefore, the restitution of the documents to the referring judges must be ordered for a new examination of the relevance and non-manifest groundlessness of the questions, in light of the changed regulatory context and constitutional jurisprudence (ex multis, orders no. 192 of 2025 and no. 210 of 2023).
FOR THESE REASONS
THE CONSTITUTIONAL COURT
having joined the cases,
1) declares the manifest inadmissibility of the questions of constitutional legitimacy regarding Art. 1, paragraphs 2 and 8, as well as Annexes A, B, C, D and E, of Sardinia Regional Law no. 20 of December 5, 2024, entitled "Urgent measures for the identification of suitable and unsuitable areas and surfaces for the installation and promotion of plants using renewable energy sources (RES) and for the simplification of authorization procedures," raised, in reference to Articles 3, 9, 41, 97, 11 and 117, first, second paragraph, letters m) and s), and third paragraph, of the Constitution, in relation to the principles expressed by Directive (EU) 2018/2001 of the European Parliament and of the Council of December 11, 2018, on the promotion of the use of energy from renewable sources and by Regulation (EU) 2018/1999 of the European Parliament and of the Council of December 11, 2018, on the Governance of the Energy Union and Climate Action amending Directives (EC) No. 663/2009 and (EC) No. 715/2009 of the European Parliament and of the Council, Directives 94/22/EC, 98/70/EC, 2009/31/EC, 2009/73/EC, 2010/31/EU, 2012/27/EU and 2013/30/EU of the European Parliament and of the Council, Council Directives 2009/119/EC and (EU) 2015/652 and repealing Regulation (EU) No. 525/2013 of the European Parliament and of the Council, both as amended by Directive (EU) 2023/2413 of the European Parliament and of the Council of October 18, 2023, amending Directive (EU) 2018/2001, Regulation (EU) 2018/1999 and Directive 98/70/EC as regards the promotion of energy from renewable sources, and repealing Council Directive (EU) 2015/652, and by Regulation (EU) 2021/1119 of the European Parliament and of the Council of June 30, 2021, establishing the framework for achieving climate neutrality and amending Regulation (EC) No. 401/2009 and Regulation (EU) 2018/1999 ("European Climate Law”); to Art. 10 of Constitutional Law no. 3 of October 18, 2001 (Amendments to Title V of Part II of the Constitution), as well as to Articles 3 and 4 of Constitutional Law no. 3 of February 26, 1948 (Special Statute for Sardinia), by the Regional Administrative Court for Lazio, Third Section, with the orders indicated in the headnote;
2) declares the manifest inadmissibility of the questions of constitutional legitimacy regarding Art. 1, paragraphs 1, 2, 6 and 8, as well as Annexes A, B, C, D, E and G of Sardinia Regional Law no. 20 of 2024, raised, in reference, overall, to Articles 3, 9, 41, 97, 11 and 117, first paragraph, in relation to the principles expressed by Directive 2018/2001/EU and Regulation 2018/1999/EU, as amended by Directive 2023/2413/EU and Regulation 2021/1119/EU, and third paragraph, of the Constitution, by the Regional Administrative Court for Sardinia, First and Second Sections, with the orders indicated in the headnote;
