This section applies if the court makes an order against C under section 66(9).
Before the end of the period of six months starting with the day on which the order is made, C may apply to the court on a ground in subsection (3) for an order and declaration under subsection (4)(a).
The grounds are—
that S failed to give C a notice under section 66(3) or failed to make the inquiries required by section 66(5);
that C considered himself or herself to be a party to the head contract or the sub-occupation contract or both of them and there is a good reason for his or her failure to respond (or to respond adequately) to the notice under section 66(3);
that, when S applied to the court, he or she did not have reasonable grounds for being satisfied that C considered himself or herself not to be a party to the head contract and the sub-occupation contract.
If the court finds that one or more of the grounds is made out, it may—
by order rescind its order under section 66(9), and declare that the head contract continues to have effect in relation to the dwelling, and
make such further order as it thinks fit.
