by the tenant. No such rates, however, were chargeable while the Commonwealth was in occupation. The value of the occupation by the Commonwealth may fairly be assessed at £6,000 per annum, the claim for rates during the period of such occupation having been abandoned.
The occupation by the Commonwealth ceased on 31st July 1944. The club was not able to use the land for the purpose of racing until 1st June 1946. I agree with my brothers Dixon and McTier- nan JJ. that the basis of compensation, as a matter of legal principle, is shown by Dalziel's Case 1 not to be the same for this period as for the period when the Commonwealth was in occupation. What is to be assessed in respect of this latter period is not the value of the occupation, but the damage to the club which was consequential upon the prior Commonwealth occupation. The club, however, was not a freeholder but was a tenant, and was bound by the terms of its lease to go on paying rent at £6,000 per annum and also to pay municipal rates, which during this period amounted to £2,083. The club, it is true, was in occupation again, but the occupation, in the circumstances, was worth nothing because, as the result of the Commonwealth occupation, the racecourse could not be used for the only purpose for which it could be used, namely, for racing. No evidence was given to show that the club could have mitigated its loss by using the racecourse for any other purpose. It is with hesitation that I differ from the decision upon this question of both of my colleagues, but I am of opinion that the payments mentioned represented an unavoidable outgoing for which no value was received as a consequence of the Commonwealth occupation, and that there- fore they may properly be taken as the measure of loss caused by that occupation for the purpose of determining the compensation which should be awarded for damage suffered by the club after the Commonwealth occupation had ceased.
Thus in my opinion the value of the occupation by the Common- wealth may fairly be assessed at £6,000 per annum in respect of the period of occupation, and the loss to the club during the period 1st July 1944 to 1st June 1946 at £6,000 per annum plus £2,083, the amount paid under the lease in respect of rates.
But it has been argued for the Commonwealth that, for various reasons, no compensation, or a smaller amount only, is payable in the circumstances of this case.
In the first place it is contended that a racecourse is a non- commercial asset which has no market value and that therefore the rule of what is called alternative re-instatement should be
