If the Minister is satisfied that a housing association have made default in giving effect to the terms of special arrangements made with the Minister for the provision of dwellings he may reduce the amount of any exchequer subsidy in respect of the dwellings or suspend or discontinue the payment thereof as he thinks just.
Where any dwelling provided by a housing association under special arrangements made with the Minister becomes vested in a local authority—
no further exchequer subsidy shall, after the time of the vesting, become payable by the Minister in respect of the dwelling, and
the Minister may, if he thinks fit, pay out of money provided by Parliament to the local authority a sum equivalent to any exchequer subsidy which would, after the said time, have become payable to the housing association in respect of the dwelling if all conditions precedent to the payment of the subsidy had been at all material times observed,
and any payment which the Minister is authorised to make under paragraph (b) of this subsection shall be included in the expression " exchequer payment" as defined in subsection (2) of section fifty-eight of the Housing (Financial Provisions) Act, 1958.
