my opinion, the delay in payment, though causing loss, is not some-
thing which is itself the subject matter of compensation for the taking;
If an employer was bound to pay fair wages to an employee, he would
be bound only to pay the amount assessed as fair wages, and not to
pay as part of the wages an additional sum because he had delayed
in the payment of the amount representing fair wages. The position
appears to me to be exactly the same in the case of fair compensation,
It was pointed out by Rich J. in The Commonwealth v. Huon Trans-
port Pty. Ltd. (1) that, where there is delay in payment, the expro-
priation of the dispossessed owner involves him in further loss
"because he is deprived both of the opportunity of obtaining revenue
from the property that once was his and of earning income or getting
benefits by the use of the money to which he has become entitled
in place of the property." His Honour drew the inference that
just terms, therefore, involve as a matter of elementary fairness the
payment of interest on the money to which the owner was entitled
for the time during which it was withheld from him. But, in my
opinion, this statement of principle (which is plainly a just prin-
ciple) shows that interest in such a case ought, as a matter of justice,
to be paid, not in respect of the loss caused by the expropriation, but
in respect of the loss caused by failure to pay promptly for the
expropriation. The proposition of which justice may be said to
require the acceptance is a proposition that, when money is owing,
on whatever ground, by one person to another, and there is a delay
in payment, the person who is under liability to pay should pay
interest to the other person as compensation for any wrongful delay
in payment. This, however, is a general proposition relating to the
requirements of justice as affecting the payment of money owing on
whatever account. It is a proposition relating not to the subject of
liability to pay on just terms for property taken, but to the indemnifi-
cation of the owner of the property against loss arising from delay in
payment. I agree that it may not be just that the Commonwealth
should at the same time have both the use of the vessel and the use
of the money which should have been paid to the owner of the vessel.
The delay may be the fault of the Commonwealth or it may be the
fault of the claimant. But in either case the damage caused by the
delay and measured by the assessment of interest is due to the delay
and not to the acquisition.
