Before this heads too far down a rabbit hole it might be worth considering which set of rules the initial agreements were signed under and also if that has been updated or if it uses rules when arbitration was notified.  All are different .  Although arbitration centers may suggest a a particular arb clause is in contracts no one other than the parties knows what conditions or standstills apply.

This is especially relevant to ability of claiming compensation from a Indian subsiduary company and court recognition if part of country  treaty at the time etc etc.

The more incorrect assumptions made the larger variance to possible result it's ability to be enforced .  We are just not aware of what the  parties originally agreed or agreed at the start of arbitration.

Security of costs - if costs are awarded and against POH they could be significant and exceed POH assets.
