Wasted cost order可以译为“浪费成本命令”，在香港译为“虚耗讼费命令”。下面分别通过英国和香港对“Wasted cost order”的规定来了解一下：

英国

The Senior Courts Act 1981 s.51(6) and (7):

(6) In any proceedings mentioned in susbsection (1), the court may disallow, or (as the case may be) order the legal or other representative concerned to meet, the whole of any wasted costs or such part of them as may be determined in accordance with rules of court. •

(7) In subsection (6), “wasted costs” means any costs incurred by a party—

(a) as a result of any improper, unreasonable or negligent act or omission on the part of any legal or other representative or any employee of such a representative; or

(b) which, in the light of any such act or omission occurring after they were incurred, the court considers it is unreasonable to expect that party to pay.

“Legal representative” is defined in CPR rule 2.3(1):

barrister;

(a) solicitor;

(b) solicitor's employee;

(c) manager of a body recognised under section 9 of the Administration of Justice Act 1985; or

(e) person who, for the purposes of the Legal Services Act 2007, is an authorised person in relation to an activity which constitutes the conduct of litigation (within the meaning of that Act).
