When there was no express designated venue, the law applicable to the seat of arbitration would be the curial law.
If a contracting party feels, his counterpart in contract committed any breach, place of committing of breach would be ordinarily place where he should ventilate his grievance. Similarly, when arbitration is held in a particular place and losing party feels, the Tribunal did not decide issue in the way it ought to have, he has to approach the Court where arbitration was held and/or award was published unless parties mutually agree to be guided by another law or law of place where contract was performed.
