The Constitutional Court has struck down the Sardinian regional law implementing Salvini's Save Homes bill, approved late last year and promptly challenged by the government. Specifically, the Constitutional Court's statement states, "the regional provision that included expansions within existing building envelopes as building renovation projects was declared unconstitutional." Further unconstitutionality "was found in the regional legislation regarding the regularization of the most serious building violations, due to the unlawful possibility of permitting, in order to obtain the regularization permit, corrective interventions not provided for by state law."

The provisions that allowed for general exemptions from the health and hygiene requirements for aerolighting established by the ministerial decree of 5 July 1975 were also rejected. Finally, the Court "annulled the regional provision that maintained the requirement for minimum parking even for changes in intended use that were not relevant from an urban planning perspective within the same functional category."

However, "questions regarding the regulation of interventions on properties subject to building amnesty were unfounded, insofar as the regional law limits such interventions to maintenance, restoration, and renovation work that does not involve increases in volume." The Constitutional Court also examined the regional regulations for demolition and reconstruction in homogeneous zones A or those of particular historical and landscape value. The related questions were declared unfounded.
