The court discusses how to interpret the Convention’s requirement that the agreement is not null and void etc., as well as specific cases of invalidity: e.g., lack of consent (misrepresentation, duress, or fraud), vague wording of the arbitral clause; other terms of the contract contradict the intention to arbitrate, etc.

The court discusses which law – lex fori, lex contractus, law of the State where the award will be made – applies specifically to determining whether an agreement to arbitrate is “null and void etc.“, and, by extension, which law applies to determining the validity of arbitration agreements.
