The instrument ignores the distinction between the preliminary
certificate of completion, or certificate of practical completion, on
the one hand, and, on the other, the certificate of the final balance.
It proceeds immediately from the progress certificates to the
certification of a single amount as the final balance payable. In
my opinion it will not fulfil the purpose of a certificate of completion,
or that of a certificate of the final balance, and does not satisfy the
condition precedent to the proprietor's liability for payment of any
amount beyond the progress payments. It will not operate as a
certificate of practical completion because it expressly states an
amount avowedly in excess of the ninety-nine per cent payable on
such a certificate, and it does not expressly state the architect's
opinion that the building is practically completed. That opinion
can only be inferred or implied from the certification of the
final amount payable. If that had been the correct amount, the
implication would have been enough to complete the certificate
according to the decisions cited above. If, on the other hand, an
express statement of the architect's judgment had been made and
no amount had been certified, a question would have arisen whether
the decision in Pashby v. Borough of Birmingham (1), or the principles
upon which it proceeded, might be applied to the present contract,
and whether the amount payable in consequence of the certificate
might be calculated aliunde. But it is quite another thing to reject
as unwarranted by the contract all that the architect has expressly
certified to, viz., the indebtedness of the proprietor in a stated
amount and its finality, to imply therefrom a certificate of a fact
not expressed, viz., the practical completion of the building, and
then from that fact to impute a liability not final and in a less amount.
