Administrative court dismisses appeal against tax authority's rectification of customs debt due to lack of legal basis.

The Supreme Administrative Court dismissed the appeal filed by Z............Portugal, S.A. against the Tax and Customs Authority's decision to rectify a customs debt. The appellant argued that the rectification lacked proper legal grounds and violated procedural rights, while the authority maintained the correction was necessary for fiscal integrity. The court ruled that without a specific legal provision authorizing the rectification in this context, the administrative act was invalid and thus the appeal failed.
