“ 17 . The scheme of Sections 12, 13 and 14, therefore, is that where an arbitrator makes a disclosure in writing which is likely to give justifiable doubts as to his independence or impartiality, the appointment of such arbitrator may be challenged under Sections 12(1) to 12(4) read with Section 13.

It is only if a controversy occurs concerning whether he has become de jure unable to perform his functions as such, that a party has to apply to the Court to decide on the termination of the mandate, unless otherwise agreed by the parties. Thus, in all Section 12(5) cases, there is no challenge procedure to be availed of.

Questions which may typically arise under Section 14 may be as to whether such person falls within any of the categories mentioned in the Seventh Schedule, or whether there is a waiver as provided in the proviso to Section 12(5) of
