The Secretary of State may by order (an "authorisation order") authorise for the purposes of section 456 any person appearing to him—
A person may be authorised generally or in respect of particular classes of case, and different persons may be authorised in respect of different classes of case.
The Secretary of State may refuse to authorise a person if he considers that his authorisation is unnecessary having regard to the fact that there are one or more other persons who have been or are likely to be authorised.
If the authorised person is an unincorporated association, proceedings brought in, or in connection with, the exercise of any function by the association as an authorised person may be brought by or against the association in the name of a body corporate whose constitution provides for the establishment of the association.
Where authorisation is revoked, the revoking order may make such provision as the Secretary of State thinks fit with respect to pending proceedings.
An order under this section is subject to negative resolution procedure.
