This article examines
the treatment of foreign administrative acts by Portuguese administrative
courts, focusing on their judicial review in the context of EU law. Despite
academic recognition of the increasing transnational nature of administrative
law, Portuguese case law on this issue remains limited. The study explores the
legal framework governing administrative acts in Portugal and analyzes relevant
case law, particularly in tax enforcement. Findings reveal that Portuguese
courts generally uphold the principle of territoriality, often refraining from
reviewing foreign administrative decisions, even when EU law permits such
scrutiny. The study highlights inconsistencies between national jurisprudence
and recent Court of Justice of the European Union rulings, particularly
regarding the right to judicial protection under Article 47 of the EU Charter.
The article concludes that, despite theoretical advancements in Portuguese
legal scholarship, judicial practice remains cautious, potentially leaving gaps
in legal protection. Future research should explore whether Portuguese courts
will align with evolving EU principles on transnational judicial review
