And I would be very happy to supervise. Thank you Nicolas Contis for flagging Stockholm National Museum v X at the French Supreme Court /Cour de Cassation. Nul ne peut se contredire au détriment d’autrui: aka (here: procedural) estoppel. (The newly out Encyclopedia of Private international law, edited by Basedow, Ruhl, Ferrari and de Miguel Asensio, has a very good entry on it, discussing both public and private international law).
On the eve of a hearing on the ownership of an ancient artefact, a cup, defendants changed their stance and argued that the cup had belonged to their mother, for whom they were acting as representatives only. Previously, they had always presented themselves as owners. They suggested therefore that the suit was misdirected, hoping to sink it. The Court of Appeal dismissed the defendants’ motion on account of procedural estoppel. The Supreme Court disagreed: its stance means, as Nicolas summarises, that ‘to face the procedural penalty of dismissal, not only must the change of stance happen throughout the judicial proceedings (ie, notably, that a contradiction including a repeated allegation made before the launching of a suit could not pass the estoppel test), but the party at fault must also have changed its ‘pretentions’ – that is, its legal claims (meaning that changing the factual allegations presented to the courts could not pass the test either)’.
I do not see entirely clear in French civil procedure law but as I saw the case reported, the thought struck me: this would be a good topic for a PhD: a comparative study in procedural estoppel, specifically in a private international law context (especially if one were also to throw a comparison with arbitration in the mix).
Happy to discuss. Geert.
