s 666 Effect of failure to re-register
(1) If a public company that is required by section 662 to apply to be re-registered as a private company fails to do so before the end of the period specified in subsection (3) of that section, Chapter 1 of Part 20 (prohibition of public offers by private company) applies to it as if it were a private company. (2) Subject to that, the company continues to be treated as a public company until it is so re-registered.
