Pamplona, 6 October 2026 – The Partido Popular (People’s Party) has filed an unconstitutionality challenge against the latest amendment to Navarra’s housing law with Spain’s Constitutional Court (Tribunal Constitucional). The reform stipulates that protected rental homes retain their status permanently and can no longer pass to the open market, as some could previously do after 21 years.
The People’s Party bases its move on constitutional concerns. It argues that the measure has impermissible retroactive effect, disproportionately restricts property rights and undermines legal certainty. In its view, the reform turns time-limited restrictions into effectively indefinite ones, thereby interfering with the concept of property protected by the Constitution.
The Government of Navarre announced that it would defend the constitutionality of the provision. Vice-President Begoña Alfaro said that they had no doubts about the lawfulness of the amendment and would take that position in the proceedings. The PSN, which passed the reform with EH Bildu, Geroa Bai and Contigo-Zurekin through the Parliament of Navarra brought forward, accused the Partido Popular of “siding with the vultures who only want to make money from housing”, instead of supporting those in need of affordable homes. UPN and the People’s Party had opposed the reform during the parliamentary debate.
The dispute reflects a wider conflict over how social housing should be designed. Representatives of the construction and property sectors had submitted reports in recent weeks raising questions about both possible interference with property rights and the division of powers between the central government and the Autonomous Communities. Supporters, by contrast, point to the social role of protected housing, curbing speculation and ensuring affordable rents.
The Tribunal Constitucional will now examine whether the Navarrese reform is compatible with the Spanish Constitution, both procedurally and substantively. It remains unclear whether the court will suspend the measure provisionally. Until a ruling is made, the legal position remains politically contested. The consequences are expected to be felt particularly by tenants in protected housing, investors and the provision of municipal housing in Navarre.
