“Parties to an assignment of a lease require certainty as between themselves as to the legal consequences of concluding their transaction, in particular as to the quality of title. It is true that that may be achievable in the end by recourse to litigation against an unreasonably recalcitrant landlord or against each other. But the purpose of a well-drawn contract of assignment is to achieve as near certainty as possible in the act of completion and without resort to the burden of uncommercial and time-consuming litigation whether as between assignor and assignee or by one or both of them against a third party, the landlord.”
“If the landlord does unreasonably withhold consent, the obligation [not to assign] ceases to bite, and the tenant is therefore free to assign without consent and may seek a declaration to that effect.”
“It was, and presumably remains, open to the assignee to apply for a declaration that the consent has been unreasonably withheld without joining the assignors of the lease as parties.”
“(1) The power of the court to grant declaratory relief is discretionary. (2) There must, in general, be a real and present dispute between the parties before the court as to the existence or extent of a legal right between them. However, the claimant does not need to have a present cause of action against the defendant. (3) Each party must, in general, be affected by the court’s determination of the issues concerning the legal right in question. (4) The fact that the claimant is not a party to the relevant contract in respect of which a declaration is sought is not fatal to an application for a declaration, provided that it is directly affected by the issue ... (5) The court will be prepared to give declaratory relief in respect of a friendly action or where there is an academic question if all parties so wish, even on private law issues ... (6) However, the court must be satisfied that all sides of the argument will be fully and properly put. It must therefore ensure that all those affected are either before it or will have their arguments put before the court. (7) In all cases, assuming that the other tests are satisfied, the court must ask: is this the most effective way of resolving the issues raised? In answering that question, it must consider the other options of resolving this issue.”
“Since a standard form is designed for use in a wide variety of transactions, there is less room for the interpretation of the form to be influenced by the background facts applicable to any particular transaction.”
“The following provisions apply if a consent to let, assign or sub-let is required to complete the contract.”
