14. Failure or impossibility to act.
The, mandate of an arbitrator shall terminate if-
he becomes de jure or de facto unable to perform his functions or for other reasons fails to act without undue delay; and
he withdraws from his office or the parties agree to the termination of his mandate.
If a controversy remains concerning any of the grounds referred to in clause (a) of sub- section (1), a party may, unless otherwise agreed by the parties, apply to the Court to decide on the termination of the mandate.
If, under this section or sub- section (3) of section 1. 3, an arbitrator withdraws from his office or a party agrees to the termination of the mandate of an arbitrator, it shall not imply acceptance of the validity of any ground referred to in this section or sub- section (3) of section 12.
