This section applies if—
In the proceedings on the claim against C, C's landlord may apply for an order for possession against the sub-holder ("S") (an "extended possession order"); but an application under this subsection may be made only if—
The requirements are as follows—
Where C's landlord may apply for an extended possession order against S, S is entitled to be a party to proceedings on the possession claim against C (regardless of whether C's landlord makes an application for an extended possession order in the proceedings).
The court may consider C's landlord's application for an extended possession order only if it has decided to make an order for possession against C.
The court may make an extended possession order against S only if, had C made a possession claim against S, the court would have made an order for possession against S.
