The Supreme Court annuls the transfer to Navarra of the Civil Guard's powers in traffic matters. The Contentious Chamber considers that this transfer cannot be made by royal decree, but requires an organic law or reform of the law of the regional regime.

According to the court, "it is obvious that any of these alternatives affects, at least, the professional interests of the civil guards" The transfer of exclusive powers over traffic and road safety, which the Basque Country and Catalonia enjoy, was a historic demand ofNavarra.
