Kommissionen er under den mundtlige forhandling i en traktatbrudssag, hvori stævningen er uklart formuleret, afskåret fra at udvide sagens genstand til at omfatte et spørgsmål, som udtrykkeligt blev udelukket ved indledningen af proceduren i medfør af EØF­traktatens artikel 169, og som ikke har været genstand for kontradik­torisk behandling, hverken inden sagsanlægget eller under skriftvekslingen for Dom­stolen.
The Commission cannot be permitted during the oral procedure to widen the scope of an ambiguously worded application to establish the failure of a State to fulfil an obligation so as to include an issue which was expressly excluded at the beginning of the procedure instituted under Article 169 and which was not considered by the parties, either during the pre-litigation procedure or during the written procedure be­fore the Court.
