Section 3 Application for assessment
Either of the following may apply for an assessment of costs relating to proceedings of Parliament on a private Bill—
a representative (or a successor of his) to whom payment of the costs is overdue,
a party who has been charged with, but who objects to, the costs.
Subsection (1) does not apply unless the representative (or a partner or successor of his) has signed a bill of the costs and—
delivered it to the party, or
sent it by post to, or left it for him at, his workplace, home or last known home address.
The application must be made—
where the proceedings took place in only one House, to the taxing officer of that House;
where they took place in both Houses, to either taxing officer.
The application must be accompanied by a true copy of the bill of costs.
If, pending an assessment of costs on an application under this section, proceedings are brought to recover the costs, those proceedings are stayed until the costs have been certified under section 8.
