It does seem to me, with more information coming out, that the SM actually did keep the OC (well at least the Secretary) informed of the actions the SM was taking. It was the OC Secretary who didn’t want to proceed with billing the tenant for the repair.
Anyway, the answer to Colosus’ original question is the OC must pay for repairs. They could try to claim costs from the owner or tenant but it would make sense for the OC to claim on building insurance and forward any excess costs to the owner who could forward them to the tenant. If the OC didn’t claim the owner could when hit with the bill.
No more from me on this thread either!
