"(1) A secure tenancy which is either - (a) a weekly or other periodic tenancy, or (b) a tenancy for a term certain but subject to termination by the landlord, cannot be brought to an end by the landlord except by obtaining an order of the court for the possession of the dwelling-house or an order under subsection (3). (2) Where the landlord obtains an order for the possession of the dwelling-house, the tenancy ends on the date on which the tenant is to give up possession in pursuance of the order. (3) . . . ."
"(1) Where proceedings are brought for possession of a dwelling-house let under a secure tenancy [for the non-payment of rent] the court may adjourn the proceedings for such period or periods as it thinks fit. (2) On the making of an order for possession of such a dwelling-house on any of those grounds, or at any time before the execution of the order, the court may - (a) stay or suspend the execution of the order, or (b) postpone the date of possession, for such period or periods as the court thinks fit. (3) on such an adjournment, stay, suspension or postponement the court - (a) shall impose conditions with respect to the payment by the tenant of arrears of rent (if any) and rent or payments in respect of occupation after the termination of the tenancy (mesne profits), unless it considers that to do so would cause exceptional hardship to the tenant or would otherwise be unreasonable, and (b) may impose such other conditions as it thinks fit. (4) If the conditions are complied with, the court may, if it thinks fit, discharge or rescind the order for possession. (5) ...."
"(2) Where the landlord obtains an order for the possession of the dwelling-house, the tenancy ends on the date on which the tenant is to give up possession in pursuance of the order."
"85(1) Where proceedings are brought for possession of a dwelling-house let under a secure tenancy on any of the grounds set out in Part I or Part III of Schedule 2 (grounds 1 to 8 and 12 to 16: cases in which the court must be satisfied that it is reasonable to make a possession order), the court may adjourn the proceedings for such period or periods as it thinks fit. (2) On the making of an order for possession of such a dwelling-house on any of those grounds, or at any time before the execution of the order, the court may - (a) stay or suspend the execution of the order, or (b) postpone the date of possession, for such period or periods as the court thinks fit. (3) On such an adjournment, stay, suspension or postponement the court - (a) shall impose conditions with respect to the payment by the tenant of arrears of rent (if any) and rent or payments in respect of occupation after the termination of the tenancy (mesne profits), unless it considers that to do so would cause exceptional hardship to the tenant or would otherwise be unreasonable, and (b) may impose such other conditions as it thinks fit. (4) If the conditions are complied with, the court may, if it thinks fit, discharge or rescind the order for possession."
"If, after a breach occurs and the tenancy is determined, and the local authority subsequently reaches agreement with the tenant the effect of which is to waive the breaches, then in my opinion in accordance with ordinary principle such breaches must be treated as if they had not occurred. It would follow from this that the tenancy must thereafter be treated as not having been determined. This appears to me to be the effect of an order which leaves the determination of the tenancy to the occurrence of a breach of the conditions of the order, and which leaves the occurrence of a breach to be dependent upon whether the landlord treats it as such or agrees to waive the breach.
"If the landlord does more and agrees not only to waive a breach of the conditions on which the order has been suspended, but also to accept payment of the arrears by smaller instalments and over a longer period than those provided for by the order, he thereby consents to such payments being treated as sufficient compliance with the order. This must either prevent the tenancy from being brought to an end or, if it has already been determined, prevent it from being so regarded."
"2. The Local Authority may waive the breach, in which case the tenancy continues as if there had been no breach. This is so whether the Local Authority agrees in advance not to treat the particular failure to comply with the terms of the order as bringing the tenancy to an end, or agrees to waive the breach after it has occurred. In either case the tenancy is treated as if it has not determined.
"3. The Local Authority may agree a consensual variation in the terms of the order. It will be a question of fact in every case whether the agreement which the parties had entered into should be characterised as an agreement which creates a new tenancy, or merely as one which provides for a variation in the terms on which the order has been suspended, waiving any past breaches and treating the tenancy as if it has not been terminated."
