F626[935. (1) For the avoidance of doubt, the following matters may, without prejudice to the generality of the provisions of section 934, be the subject of an investigation by the Supervisory Authority under that section, namely matters—

(a) in relation to which a recognised accountancy body has decided not to withdraw a person’s approval under F627[Part 27] as a statutory auditor or audit F1[firm or approval under Part 28 to carry out the assurance of sustainability reporting], or

(b) which either—

(i) have not been considered by a recognised accountancy body as grounds for the withdrawal of a person’s approval under F627[that Part] as a statutory auditor or audit firm, or

(ii) having been considered by it as such grounds, are not considered by it to disclose a prima facie case for proceeding further.

(2) Where—

(a) those matters are the subject of such an investigation by the Supervisory Authority, and

(b) a breach of standards is found by the Supervisory Authority,

F627[section 934(8)] shall be read as requiring or enabling (depending on whether the breach of standards found falls within F627[Chapters 2 to 4, or Chapter 8, of F1[Part 27 or Chapters 4 to 7 of Part 28]]) the Supervisory Authority to withdraw the approval under F1[the relevant Part] of the person concerned as a statutory auditor or audit firm.

F627[(3) Where such an approval is withdrawn by the Supervisory Authority, section 1479(13) to (15) or, as the case may be, section 1480(13) to (15), shall, with all necessary modifications, apply to that withdrawal and section 934(11) and (12) shall not apply to that withdrawal.]

(4) Subsection (2) does not prejudice the imposition, in the circumstances concerned, by the Supervisory Authority of another sanction referred to in F627[section 934(8)] in addition to a withdrawal of approval (where withdrawal of the approval is mandatory under F1[Part 27 or Part 28]) or in lieu of a withdrawal of approval (where such withdrawal is not so mandatory).

(5) For the purposes of section 934, "member", in addition to the meaning given to that expression by section 900(1), includes, in relation to a prescribed accountancy body that is a recognised accountancy body, an individual or firm who or which, though not a member of the recognised accountancy body, is an individual or firm in relation to whom that body may exercise powers under F1[Part 27 or Part 28].]
