Wine-Sector Jurisprudence
Decisions of the Portuguese and European courts on wine-sector matters, with thematic indexing and standardised reference. Updated in 2026.
Methodological note
This archive gathers decisions identified through research in the official systems (DGSI, EUR-Lex, ECLI). The indexing is informative and editorial in nature — it does not constitute an exhaustive legal database and does not replace specialised advice. Decisions are referenced by their official designation and summarised thematically.
Sector administrative, regulatory and tax litigation
Labelling and the IVV's supervisory powers
Decision of the Southern Central Administrative Court on the supervisory powers of the Institute of Vine and Wine (IVV) over wine-product labelling. The court delimited the scope of IVV intervention as against ASAE, clarifying each authority's subject-matter competence.
IFAP and vineyard conversion/restructuring (VITIS)
Decision on access to support under the VITIS programme for vineyard conversion and restructuring. The court ruled on eligibility requirements and the scope of judicial review of IFAP decisions on agricultural funds.
IVDP, correction and demineralisation
Decision of the Central Administrative Court on oenological practices authorised by the IVDP under the Port PDO. The judgment addressed the distinction between permissible correction practices and adulteration, with direct implications for producers' regulatory compliance.
Casa do Douro and the organisation of Douro viticulture
Judgment on the legal nature of Casa do Douro and its powers within the interprofessional organisation of Douro viticulture, analysing the interplay between association law and the special wine-sector law applicable to the Douro Demarcated Region.

Civil, commercial and distinctive-property matters
IVDP / INPI / trade mark — Lisbon Court of Appeal
Judgment on conflict between a trade mark sign and the "Porto" designation of origin, analysing the criteria for likelihood of confusion and the relationship between trade mark registration and the protection of geographical indications under national and European law.
Protection of the "Porto" DO and the "Port" designation
Leading decision on the scope of protection of the "Porto" Designation of Origin and its extension to the English-language designation "Port". The court delimited the requirements for applying Article 103 of Regulation (EU) No 1308/2013 and protection against evocative and indirect uses.
"CARLO PORTO" / reproduction of the word "PORTO"
Judgment on the use of the expression "CARLO PORTO" as a trade mark for a wine product. The court considered whether incorporating the word "PORTO" constituted prohibited reproduction of the designation of origin or unfair exploitation of its reputation, analysing European GI law and CJEU case law.

Class 33, wines/spirits/liqueurs and likelihood of confusion
Judgment of the Supreme Court of Justice on a trade mark conflict in Class 33 (wines, spirits and liqueurs). The Court ruled on the criteria for assessing likelihood of confusion where the products concerned span several sub-categories of the same NICE class, with implications for trade mark filing strategy in the sector.
Administrative offences, tax and sanctions
