The court discusses the meaning and effect of the referral of the resolution of disputes to arbitration, including: who can ask for referral and when, whether a party has waived its right to request arbitration, the defense that there was no contract at all; whether there was a condition precedent to the commencement of arbitration (e.g. mediation), stay of proceedings v. compelling arbitration, and national procedural specificities such as remand and removal (US), effect of class action. etc.

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.

Multi-party disputes: The court discusses whether related court proceedings may absorb (by vis atractiva) arbitration proceedings.
