Les échanges commerciaux se montrent aujourd’hui, difficilement prévisibles. Les entreprises, pour faire face à ce brouillard d’aléas, doivent être agiles et adaptables. Le contrat en est l’une des expressions. Il doit, à cet effet, reposer sur la souplesse et l’adaptabilité pour réduire sa vulnérabilité aux circonstances. Le colloque se propose, avec des professeurs, des praticiens juristes et des économistes, de faire un tour d’horizon des techniques contractuelles qui permettent de préserver l’économie des contrats face aux incertitudes et aux changements en favorisant le dialogue et la coopération entre les parties.

La construction du contrat

  • 10:00 1ère table ronde
    La souplesse organisée par les clauses contractuelles générales : point sur les pratiques et nouvelles orientations

    Le traitement contractuel des incertitudes et changements par des clauses de type force majeure, hardship, clause de révision, mis à mal par un certain nombre d’évènements disruptifs majeurs (COVID 19, Guerre en Ukraine…) évolue vers l’utilisation de clauses « paysage » ou de revoyure apportant davantage de souplesse par la promotion de la collaboration entre les parties.

    Intervenants : Arnaud de Nanteuil ; Pascale Accaoui Lorfing ; Denis Philippe ; Delphine Jacquemont.

    Modérateur : Henry Lesguillons.

  • Pause

  • 10:30 2ème table ronde
    Les mécanismes de souplesse propres aux contrats dits coopératifs : les contrats d’Alliance et les contrats de type « Agile »

    Les modèles de contrat de construction anglo-saxons de type Alliance qui se renforcent à l’international (FAC-1; TAC1; NEC4 ALC et FIDIC Alliance prochainement) adoptent une structuration plus souple fondée sur la collaboration entre les parties, la gestion mutuelle des risques et la transparence à l’inverse des contrats EPC- clé en mains. Les modèles dits « Agile » vont encore plus loin impliquant une adaptation permanente.

    Intervenants : [Richard Patterson] ;[Danuda Kokhreide] ; Sophie Deis-Beauquesne ; Bruno de Cazalet ; Pierrick Le Goff ; Alexandre Cruquenaire ; Gilles Pillet ; Alexandra Berg Moussa.

  • Cocktail déjeunatoire

L’exécution du contrat

  • 14:15 3ème table ronde
    L’évolution du rôle des acteurs internes et externes comme facilitateurs d’une exécution plus souple du contrat

    Comment s’organise et s’agence l’intervention des acteurs tels que les « contract manager », « alliance manager », conciliateur, médiateur, adjudicateur, conseil de sages, etc.., avant le recours aux procédures contentieuses ?

    Intervenants : Gabriel Ermanet ; Alain Brunet ; Pierrick Le Goff ; Hakim Boularbah ; Pierre Genton ; [Peter Roscher] ; Maude Lebois ; [Pascal Hollander].

    Modérateurs : Pierrick Le Goff ; Gilles Pillet.

  • Pause

  • 16:00 4ème table ronde
    Les contrats à l’épreuve d’incidents disruptifs : retours d’expérience (pandémies, guerres, crises géopolitiques, dérèglement climatique…)

    Curieusement la pandémie COVID 19 n’a pas été suivie d’une avalanche de procédures contentieuses, car de nombreux Etats sont venus au secours de leurs entreprises et de leur économie indépendamment des contrats. La variété et le cumul d’incidents disruptifs obligent cependant les juristes à se mobiliser face à ces incertitudes et changements pour assurer l’adaptation des règles contractuelles.
