Challenge to foreign nationals regulation 2026: what risk does it pose for companies with foreign workers

Key data

The modifications to the foreign nationals regulation approved in April 2026 through Royal Decree 316/2026 are in limbo. The Ahora España party has filed administrative litigation case 1/300/2026 before the Supreme Court, and the General Technical Secretariat has already sent the administrative file to the Administrative Litigation Chamber, Fifth Section.

This means the judicial procedure is underway. The resolution activating the deadline to appear was published in the Official Gazette on 31 July 2026. From that point, the clock is ticking for those who want to defend the regulation.

What does this regulation establish?

The resolution published on 31 July 2026 does not directly modify the foreign nationals regulation: what it does is formalize the start of the judicial procedure against it. Specifically:

• The General Technical Secretariat-Government Secretariat sends to the Supreme Court the complete administrative file corresponding to case 1/300/2026.
• The appellant is the political party Ahora España, which challenges Royal Decree 316/2026.
• Said Royal Decree modified the Regulation of Organic Law 4/2000, which regulates the rights and freedoms of foreigners in Spain and their social integration.
• The procedure is governed by articles 48 and 49 of Law 29/1998 on Administrative Litigation Jurisdiction.
• Persons or entities with legitimate interest in defending the validity of Royal Decree 316/2026 are called upon to appear as defendants within 9 days from publication in the Official Gazette.

In practice, as long as the Supreme Court does not issue a precautionary suspension measure, Royal Decree 316/2026 remains in force. However, legal uncertainty is real: if the Supreme Court were to uphold the appeal, the regulatory modifications approved in April 2026 would be annulled.

Economic and operational impact

The immediate impact for most companies is regulatory uncertainty, not direct cost. But that uncertainty has concrete operational consequences:

• Residence and work procedures in progress: Cases initiated under the modifications of RD 316/2026 could be affected if the Supreme Court annuls them. This creates risk for companies that have initiated foreign worker hiring processes under the new regulatory conditions.
• HR planning: Companies that depend on foreign workers—especially in sectors such as hospitality, construction, agriculture or technology—must consider alternative scenarios if the regulation is suspended or annulled.
• Legal advisory cost: Entities with legitimate interest who wish to appear in the procedure will have to assume legal representation costs before the Supreme Court.
• Risk of procedure paralysis: Depending on how the procedure evolves, the Administration could adopt more conservative criteria in processing foreign nationals cases until there is a judicial ruling.

Who does it affect?

• Companies with foreign workers that have initiated or plan to initiate residence or work authorization procedures under RD 316/2026.
• Foreigners residing in Spain whose residence or work cases are linked to the regulatory modifications of April 2026.
• Law firms and management consultancies specializing in foreign nationals matters advising companies or individuals in these procedures.
• Business associations and employers' organizations in sectors intensive in foreign labor (hospitality, construction, agriculture, domestic services, technology).
• Entities with legitimate interest in defending the validity of Royal Decree 316/2026, which have 9 days from 31 July 2026 to appear as defendants before the Supreme Court.
• NGOs and institutions working on social integration of foreigners that could be affected by a possible change in the regulatory framework.

Practical example

Imagine a construction company that in May 2026 initiated the hiring process for 10 foreign workers, relying on the new conditions introduced by Royal Decree 316/2026 in the foreign nationals regulation. The cases are being processed.

With case 1/300/2026 already admitted to the Supreme Court, this company faces two scenarios:

• Scenario A (the appeal does not succeed): RD 316/2026 remains intact. The cases proceed normally and workers obtain their authorizations under the new regulatory conditions.
• Scenario B (the appeal succeeds or a precautionary measure is issued): The modifications of RD 316/2026 are annulled or suspended. Cases being processed could be paralyzed or have to be redirected to the previous regulatory framework, with the administrative cost and time that entails.

Additionally, if this company has legitimate interest in maintaining the Royal Decree, it should assess—with its legal advisor—whether to appear as a defendant before the deadline of 9 days from 31 July 2026 expires.

What should companies do now?

1. Identify if you have active cases under RD 316/2026: Review with your advisory team if any residence or work authorization procedure in progress is based on the regulatory modifications of April 2026. These are the most exposed to uncertainty.
2. Assess if you have legitimate interest to appear: If your company or association has a direct interest in Royal Decree 316/2026 remaining in force, urgently consult with a lawyer specializing in administrative litigation. The 9-day deadline from 31 July 2026 is very short.
3. Monitor the judicial procedure: Follow the progress of case 1/300/2026 before the Supreme Court. A precautionary suspension measure would have immediate effects on cases in progress.
4. Prepare a contingency plan: If your business model depends on hiring foreign workers under the new regulatory conditions, design an alternative scenario based on the regulatory framework prior to RD 316/2026.
5. Inform your HR department: The team managing hiring must be aware of this uncertainty to avoid compromising incorporation deadlines that depend on work authorizations currently being processed.
