CAA (C-629/10; referring court: High Court of Justice / England & Wales, Queen’s Bench Division / Administrative Court).Both references seek a revision of the “Sturgeon” judgement (judgment of Nov. 19, 2009 in joined cases C-402/07 and C-432/07) by questioning the vailidity of Articles 5-7 Reg. 261/2004 as interpreted there with regard tothe principle of equal treatmentthe principle of proportionalitythe principle of legal certainty andthe Montreal ConventionWhile some more references concerning Reg. 261/2004 as interpreted in the Sturgeon judgement are still pending, it will be exciting to see how the court will solve the controversy which arose from “Sturgeon” and which in some member states led to a stay of cases seeking compensation for delay pursuant to Articles 5-7 Reg. 261/2004.
