International Technologies, Inc. (ITI) filed a claim for refund for unutilized input VAT with the Court of Tax Appeals (CTA). In the course of the trial, ITI engaged the services of an independent Certified Public Accountant (CPA) who examined the voluminous invoices and receipts of ITI. ITI offered in evidence only the summary prepared by the CPA, without the invoices and the receipts, and then submitted the case for decision. Can the CTA grant ITI's claim for refund based only on the CPA's summary? Explain.
