This Article applies where a body of a prescribed description undertakes to meet (in accordance with arrangements satisfying prescribed conditions) liabilities which members of the body or other persons who are parties to proceedings may incur to pay the costs of other parties to the proceedings.

If in any of the proceedings a costs order is made in favour of any of the members or other persons, the costs payable to him may, subject to paragraph (3) and (in the case of court proceedings) to rules of court, include an additional amount in respect of any provision made by or on behalf of the body in connection with the proceedings against the risk of having to meet such liabilities.

But the additional amount shall not exceed a sum determined in a prescribed manner; and there may, in particular, be prescribed as a manner of determination one which takes into account the likely cost to the member or other person of the premium of an insurance policy against the risk of incurring a liability to pay the costs of other parties to the proceedings.

Regulations under paragraph (1) may, in particular, prescribe as a description of body one which is for the time being approved by the Lord Chancellor or a prescribed person.
