Muscat brought a claim for possession based on the arrears of rent. Smith defended the claim on the basis that he could set against the arrears of rent the compensation he was due as a result of Walker's failure to repair. Muscat said Smith had to take a case against Walker in respect of that.
The Court of Appeal decided that "setting-off" compensation accruing against the old landlord in a claim brought by a new landlord was legally permissible. The new owner took the benefit of the old arrears and with them the burden of the previous landlord's default. It sent the case back to the local county court to decide how much compensation was due and what proportion of the arrears that would extinguish.

This decision is important for transfers. It enables a council tenant who has not sued the council for past disrepair to raise that claim for compensation in rent arrears proceedings brought by the RSL after transfer. RSLs need to estimate potential liability at the point of transfer or seek an indemnity from the council.
