A 48-hour deadline has forced the parties to argue over Spain’s overseas voter register. The ruling could decide whether thousands of nationalized citizens vote on 29 November.
The electoral census for Spaniards abroad closed on 1 August 2026, before the Supreme Court issued its September suspension. That timing now controls a dispute involving citizens who obtained Spanish nationality through the ley de nietos.
Pedro Sánchez’s announcement of early general elections for 29 November accelerated the case. The court must decide whether its precautionary measure can reach a census that had already been finalized.
On Tuesday, the judges gave the parties an irrevocable 48-hour period to submit arguments. A ruling could arrive as early as this weekend, before overseas voting arrangements move forward.
The September precautionary measure does not cover every citizen naturalized under Spain’s Democratic Memory Law. It excludes people who can present a consular certificate proving that an ancestor was exiled for political, ideological or sexual-orientation-related reasons.
The case began when Iustitia Europa and Vox challenged the possible electoral impact of the nationality route. Iustitia Europa asked the court to ensure that its precautionary order applied to the coming election, warning that the reference census had closed before the suspension was issued. Vox filed a similar request hours later.
The Government and the Fiscalía support lifting the suspension so Spanish citizens abroad can vote. Their argument rests on the structure of the Censo Electoral de Residentes Ausentes. The register does not identify nationality routes in a form that would let officials separate citizens who used the ley de nietos from those who became Spanish through other channels within the short deadlines imposed by electoral law.
That position created the central procedural clash. The court asked the State Legal Service for its view. It also requested positions from the Central Electoral Commission, the prosecution service, Iustitia Europa and Vox. One question is whether thousands of naturalized citizens directly affected by the suspension must formally join the proceedings.
Iustitia Europa has asked the Supreme Court for information on the number of affected census entries, the people already identified and those who fall within the exception for applicants who have proved an ancestor’s exile. Vox has separately urged the Central Electoral Commission not to grant effective voting rights to people whose entries were already present in the CERA on 1 August.
Iustitia Europa has turned the Government’s own argument against the election timetable. It says the existing census should not remain in place if the Supreme Court’s September order cannot be enforced through it.
Issued between 8 and 10 September, that order halted voting and new census registrations for people nationalized through the ley de nietos who could not prove that their descendants had been exiled. The measure does not cover every person who received nationality under Spain’s Democratic Memory Law. It targets the category tied to the disputed presumption of exile, unless applicants provide the required proof.
The nationality process is large enough to drive the court’s concern. The Ministry of Foreign Affairs says it received more than 1.2 million applications and approved 571,761. Consular offices recorded 333,696 registrations. The CERA contained 2,736,522 electors on 1 July 2026, compared with 2,328,260 for the 2023 general election. That is an increase of 408,262 registered voters.
Those figures prompted the magistrates to warn that the growth could affect voting rights and the electoral result sought by Spaniards already correctly included in the census. In September, the court described the increase as a real and serious danger to the objectivity and transparency of the process. It presented the precautionary measure as temporary and dependent on the final judgment.
RTVE and El País identified 29 November 2026 as the election date. One separate account referred to 29 September, creating a conflicting date in the reporting. The available material from RTVE, El País and statements by participants supports 29 November.
Inside the court, Magistrate María Alicia Millán opposed the measure in a separate opinion. She argued that it deprived a potentially large number of citizens of one of the most important effects of Spanish nationality, the right to vote. Her view was that the increase in Spanish citizens did not by itself create the qualified risk required to suspend their participation.
Félix Bolaños has pressed the Supreme Court to decide the substance of the case quickly. The minister warned that the census would be altered if the precautionary measure continued. He described excluding Spanish citizens from voting as a decision of major importance. The wider election buildup around the 29 November contest is already moving quickly.
The practical choice is narrow. The overseas census can remain untouched, or the court must find a workable way to enforce a distinction that the Government says cannot be made in time. The ley de nietos was introduced through an additional provision of the 2022 Democratic Memory Law. It covers descendants of exiles, alongside specified cases involving women who lost Spanish nationality through marriage and other legally recognized routes.
The Supreme Court must decide whether the temporary safeguard can take priority over the existing voting process while also confronting the concrete cost identified in the dissent: withholding the vote from citizens whose nationality has already been recognized.
