Arbitration is meant to be a flexible, party-driven process, and Section 20 reflects that philosophy by giving the parties the first say over where their arbitration will be seated.
Problems only arise when the parties cannot agree on this point themselves, and it is here that Section 20(2) steps in to hand the decision to the arbitral tribunal rather than to any court.
Instead of fixing a single rigid rule such as the place of signing the contract or the place where the disputed property sits, the provision keeps the same flexible spirit that runs through the rest of the Act, telling the tribunal to weigh the circumstances of the case as a whole, with particular attention to what would be convenient for the parties involved. This approach lets the tribunal account for things like where the parties are based, where evidence and witnesses are located, and practical costs of travel, rather than being locked into one fixed geographic marker.
A rule based on the place of signing would ignore how much has changed since the contract was made, and a rule tied to a civil court's jurisdiction would contradict the very idea of taking the dispute out of the court system in the first place, so neither fits the scheme.
The provision that actually governs is the one asking the tribunal to look at the circumstances of the case, including party convenience.
