Highfield Resources (ASX:HFR) said the governments of Navarra, Aragón, and Spain applied to the Spanish Supreme Court for leave to appeal the regional Superior Court of Justice of Navarra ruling relating to a procedural flaw in the internal administrative coordination process in relation to the granting of the Goyo mining concession, according to a Thursday Australian bourse filing.

The procedural flaw related to the fact that while Highfield had received government advice to apply for three separate mining concessions in 2014, Goyo, Muga, and Fronterizo, the Superior Court of Justice held that, procedurally, a single unified concession should have been issued.

Highfield is working with the governments of Navarra, Aragón, and Spain regarding a solution with respect to the Goyo mining concession.
