21.—(1) Subject to the provisions of this Part, a concurrent wrongdoer (for this purpose called the claimant) may recover contribution from any other wrongdoer who is, or would if sued at the time of the wrong have been, liable in respect of the same damage (for this purpose called the contributor), so, however, that no person shall be entitled to recover contribution under this Part from any person entitled to be indemnified by him in respect of the liability in respect of which the contribution is sought.

(2) In any proceedings for contribution under this Part, the amount of the contribution recoverable from any contributor shall be such as may be found by the court to be just and equitable having regard to the degree of that contributor’s fault, and the court shall have power to exempt any person from liability to make contribution or to direct that the contribution to be recovered from any contributor shall amount to a complete indemnity.
