Spain’s Supreme Court has suspended voting rights for people naturalized under the law of grandchildren, citing a surge in overseas voter registrations and concerns about election integrity. The decision affects thousands and has sparked legal and political debate.
People who gained Spanish citizenship through the law of grandchildren have had their voting rights suspended by Spain’s Supreme Court. Announced this week, the decision targets a recent wave of new citizens whose eligibility was fast-tracked under a broad reading of the law. Their inclusion in the overseas electoral roll is on hold while the courts review the case.
The court’s basic concern is the sharp rise in registrations in the Censo Electoral de Residentes Ausentes (CERA), the list of Spaniards living abroad. As of July 1, 2026, CERA had 2,736,522 registered voters, 408,262 more than at the 2023 general election. Madrid and Barcelona saw especially large jumps in overseas voter numbers, raising questions about whether these new voters could influence election results and public trust in the process. The Supreme Court clarified that the suspension does not affect people who can document their status as descendants of exiles under the Democratic Memory Law.
The judges argued that letting these new citizens vote could permanently change the outcome of any election held before the legal dispute is settled. They said suspending the registrations now was necessary: otherwise, a future ruling would be pointless because the votes would already have been counted. The court aims to keep things as they are until the legality of the mass naturalizations is resolved. Statements cited by El País said the court wants to avoid consequences that cannot be reversed later.
The dispute centers on an instruction from the Dirección General de Seguridad Jurídica y Fé Pública, then led by Sofía Puente, sister of current minister Óscar Puente. The Supreme Court found that the Ministry of Justice’s interpretation, which allowed thousands to claim citizenship under the law of grandchildren, did not match the text of the law. The administrative decision is under review and has become a point of political and legal contention. Several legal analysts have noted that the issue is how the Ministry applied the law, not the law itself.
The suspension follows appeals from Iustitia Europa and Vox, after the Junta Electoral Central declined to act. The Supreme Court’s decision was not unanimous: one judge dissented, reflecting divisions within the judiciary. Supporters of the suspension, including Vox and Iustitia Europa, say it is needed to protect electoral transparency. The State Prosecutor’s Office opposes the freeze, arguing that it violates the constitutional right to vote. The Spanish government, through Minister Félix Bolaños, has urged the Supreme Court to resolve the dispute as quickly as possible, ideally before the 2027 elections, to avoid prolonged legal uncertainty affecting the next electoral cycle. The State Prosecutor has also formally objected to the suspension, emphasizing the fundamental nature of voting rights in Spain’s constitution.
Spain’s electoral system has faced scrutiny before, including in a recent investigation into judicial independence and border security. This latest Supreme Court intervention goes to the heart of who can vote and under what conditions.
For the hundreds of thousands affected, the immediate result is clear: their right to vote is suspended until the courts make a final decision. The case has reopened debate about how to balance expanding citizenship with protecting election integrity. The court’s willingness to overrule a government department shows a judiciary ready to assert itself on major national questions. The episode highlights how quickly Spain’s electoral system can be tested by rapid demographic changes and administrative shortcuts. For now, new citizens under the law of grandchildren will have to wait for a final ruling before they can vote.
