"This Agreement shall operate for a period of seven years from the date hereof and if during the six months prior to the expiration of the said term the Operator shall serve written notice upon the Owner requesting the renewal of the Agreement for a further period of seven years then subject to the re-negotiation of the rent payable in no less a sum than that which shall be payable under the terms of this Agreement at that date the Owner shall grant to the Operator a fresh agreement in the same terms hereof save and except for this clause for a further period of seven years."
"The yearly rent payable under this Agreement shall be reviewed annually and the new rent payable for each year shall come into effect on the anniversary of the commencement of this Agreement and the rent for each year shall be the rent payable for the previous year of this Agreement multiplied by one plus the percentage increase in the index of retail prices maintained by the Department of Employment for the twelve months ending on the 1st day of July immediately preceding the end of each period of one year and shall form the base rent for the calculation of the following year."
"There is no doubt in my mind that clause 4 was intended by the parties to have legal effect. The agreement was formally drawn, and there is no dispute that, apart from clause 4, it had legal effect, whether as a licence or as a lease, and I can see no good reason for the supposition that clause 4 was not intended to have legal effect equally with the rest of the agreement. Moreover, it is clear that in cases where a clause such as clause 4 is intended to have legal effect, the predisposition of the court is to try to give effect to such a clause. In Corson v Rhuddlan Borough Council , the Court of Appeal, in connection with an option to renew a lease of a golf club which provided for a rental to be agreed but subject to a maximum of the amount payable under the original lease, held that the validity of a rent determination provision did not depend on whether it was included in a continuing lease or an option to renew, and felt able to conclude that the provision in that option for a maximum amount in relation to the renewal was sufficient to enable the implication of a term for the payment of a fair rent. In my judgment a similar analysis can properly be conducted in relation to clause 4, bearing in mind that there is a provision for what is in effect a minimum rent. The result is that, in my judgment, the defendant has a good case that the provisions of clause 4 are valid, which, subject to the question of breach, provides them with a defence to this action."
