1. When as per the arbitration agreement, the appointing authority is approached by one of the parties for appointing arbitrator; is it open for appointing authority to decide on merit of the claim of the party as to whether for claimed dispute arbitrator can be appointed or not?
2. Can the appointing authority under any circumstance reject request for appointment of an arbitrator?
The answer to your query is in negative for the reason that until and unless the Arbitration Agreement specifically provides for the right to the Arbitrator appointing authority it cannot go into the merit i.e. to see whether any dispute is arbitrable or not.
More so, it is a sort of an administrative act and the same needs to be done transparently, without any malice or favour.
