41 On the other hand, in Baese Pty Ltd v RA Bracken Building Pty Ltd (1990) 6 BCL 137, in respect of a contract in different terms, it was held that the insertion of 'nil' as the rate of liquidated damages was not an exhaustive statement of the owner's rights in the event of a failure to complete on time. In that case, the contract provided, in effect, that if the builder failed to complete the work by the due date the architect may issue a certificate of non-completion and, in that event, the builder was required to pay liquidated damages to the owner at the specified rate. Giles J distinguished Temloc on the basis of the different wording of the contract, pointing out that, unlike Temloc, the clause was not mandatory and self-executing (in that it depended upon the issue of a certificate which the architect 'may' issue) and also unlike Temloc, it was not contained under a heading 'Damages for non-completion'.
