Difficulties arose in particular where the applicable treaty was designed to facilitate recognition and enforcement of court judgements, but the treaty itself did not allow recognition or enforcement to be refused on the ground that the dispute dealt with by the judgement was covered by an arbitration agreement, was being considered in a pending arbitral proceeding, or was the subject matter of an arbitral award.
Las dificultades surgían en particular cuando un tratado, destinado a facilitar el reconocimiento y la ejecución de sentencias judiciales, no permitía que se denegara el reconocimiento o la ejecución de esas sentencias por motivo de que la controversia objeto de la sentencia estuviera al amparo de un acuerdo de arbitraje, o estuviera siendo considerada en un proceso arbitral en curso o hubiera sido ya objeto de un laudo arbitral.
