"The tenancy shall continue until the said land is required by the Council for the purposes of the widening of Walworth Road and the street paving works rendered necessary thereby and the Council shall give two months' notice to the tenant at least prior to the day of determination when the said land is so required and thereupon the tenant shall give vacant possession to the Council of the said land . . ."
"'Terminus' in the understanding of the law does not only signify the limits and limitation of time, but also the estate and interest that passes for that time."
"Every estate which must expire at a period certain and prefixed, by whatever words created, is an estate for years. And therefore this estate is frequently called a term, 'terminus', because its duration or continuance is bounded, limited and determined: for every such estate must have a certain beginning, and certain end."
"Every contract sufficient to make a lease for years ought to have certainty in three limitations, viz. in the commencement of the term, in the continuance of it, and in the end of it; so that all these ought to be known at the commencement of the lease, and words in a lease, which don't make this appear, are but babble . . . And these three are in effect but one matter, showing the certainty of the time for which the lessee shall have the land, and if any of these fail, it is not a good lease, for then there wants certainty."
"1(1) The only estates in land which are capable of subsisting or of being conveyed or created at law are -
"Normally there could be no question that this was an ordinary weekly tenancy, duly determinable by a week's notice, but the parties in the rent-book agreed to a term which appears there expressed by the words 'furnished for duration,' which must mean the duration of the war. The question immediately arises whether a tenancy for the duration of the war creates a good leasehold interest. In my opinion, it does not. A term created by a leasehold tenancy agreement must be expressed either with certainty and specifically or by reference to something which can, at the time when the lease takes effect, be looked to as a certain ascertainment of what the term is meant to be. In the present case, when this tenancy agreement took effect, the term was completely uncertain. It was impossible to say how long the tenancy would last. Mr Sturge in his argument has maintained that such a lease would be valid, and that, even if the term is uncertain at its beginning when the lease takes effect, the fact that at some future time it will be rendered certain is sufficient to make it a good lease. In my opinion that argument is not to be sustained. I do not propose to go into the authorities on the matter, but in Foa's 'Landlord and Tenant' 6th ed., p. 115, the law is stated in this way, and, in my view, correctly:
'The habendum in a lease must point out the period during which the enjoyment of the premises is to be had; so that the duration, as well as the commencement of the term, must be stated. The certainty of a lease as to its continuance must be ascertainable either by the express limitation of the parties at the time the lease is made, or by reference to some collateral act which may, with equal certainty, measure the continuance of it, otherwise it is void . . ."'
"1(1) ... shall have effect as if it granted or provided for the grant of a tenancy for a term of ten years, subject to a right exercisable either by the landlord
"Though the agreement be void by the Statute of Frauds as to the duration of the lease, it must regulate the terms on which the tenancy subsists in other respects, as to the rent, the time of year when the tenant is to quit, etc. . . . Now, in this case, it was agreed, that the defendant should quit at Candlemas; and though the agreement is void as to the number of years for which the defendant was to hold, if the lessor choose to determine the tenancy before the expiration of the seven years, he can only put an end to it at Candlemas."
"What estate the defendant was contended to have? And whether he were not in this dilemma; that either his estate might enure for life, at his option; and then according to Lord Coke such an estate would, in legal contemplation, be an estate for life; which could not be created by parol: or if not for life, being for no assignable period, it must operate as a tenancy from year to year; in which case it would be inconsistent with, and repugnant to the nature of such an estate, that it should not be determinable at the pleasure of either party giving the regular notice."
"If this interest be not determinable so long as the tenant complies with the terms of the agreement, it would operate as an estate for life; which can only be created by deed . . . The notion of a tenancy from year to year, the lessor binding himself not to give notice to quit, which was once thrown out by Lord Mansfield, has been long exploded."
"This reasoning applies with at least equal force to the present case. This is not a mere constructive tenancy as that was. It is as explicit as words can make it that the defendants are to hold 'upon a weekly tenancy at a weekly rental, and that the tenancy is to be determined by either of the parties on giving a week's notice to the other.' There is this difference between the two cases, that in Doe d. Browne v. Warner the lessor engaged not to turn out the tenant so long as he observed the conditions, and in this case Radcliffe engages that the tenant shall hold until the company require to pull down the buildings. But, as that is an event which may never happen, the distinction is merely between the contingency of the tenant breaking the conditions and the contingency of the company wanting the premises in order to pull them down. The restriction is as repugnant to the nature of the tenancy in the one case as is in the other. It is therefore no legal answer to the ejectment to say that the contingency provided for has not happened."
"... we are persuaded that, there being no authority to prevent us, it is preferable as a matter of justice to hold parties to their clearly expressed bargain rather than to introduce for the first time in 1971 an extension of a doctrine of land law so as to deny the efficacy of that bargain."
