Parterne skal, med undtagelse af medlemsstater, andre stater, som er parter i EØS-aftalen (Norge, Island og Liechtenstein), og Den Europæiske Unions institutioner, som repræsenteres af deres befuldmægtigede, lade sig repræsentere af en advokat, der har beskikkelse i en medlemsstat eller i en anden stat, som er part i EØS.
With the exception of the Member States, other States which are parties to the EEA Agreement (Norway, Iceland and Liechtenstein) and the institutions of the European Union, which are represented by their agents, the parties must therefore be represented by a lawyer authorised to practise before a court of a Member State or of another State party to the EEA Agreement.
