“The appellant valuation officer, in giving evidence in support of a valuation other than nominal, maintained that if the conveniences were vacant and to let there would be at least two potential tenants who would have an interest in bidding for a lease: the owner of the centre and a consortium of tenants. I think that the issue as to whether a value more than nominal is to be attributed to the appeal property depends upon whether such potential bidders would, between them, bid the rent up. I think that Mr King gave the right answer to that question in his evidence in cross examination. 8 He pointed out that the tenants of the retail units have to pay a service charge equal to the cost of providing the services including the conveniences. Any rent which the owner of the centre had to pay would be charged back to the tenants. It would not be in the interest of the tenants to bid against the owner, who would therefore either be the only potential tenant or would agree with the consortium that they should be the only bidders for the tenancy. In the hands of the hypothetical lessor, or of any third party, the premises, subject to the rights of the tenants of the retail premises would be burdensome and incapable of producing any income for him that was not exceeded by the expense of collecting it. The hypothetical lessor would not, therefore, be able to insist on more than a nominal rent.”
