However, it is not sufficient to recognize that the delay in construction of a newly built restaurant at the B center was caused by the delay in metal and windows due to the plaintiff's causes attributable to the delay in construction, or that there was a defect in the plaintiff's construction, and there is no other evidence to acknowledge

3. The plaintiff's claim for the conclusion is justified and it is so decided as per Disposition by the assent of all participating Justices.
