G.R. No. 148187; April 16, 2008
PHILEX MINING CORPORATION, petitioner, vs. COMMISSIONER OF INTERNAL REVENUE, respondent.

FACTS

Petitioner Philex Mining Corporation entered into a “Power of Attorney” with Baguio Gold Mining Company on April 16, 1971, to manage and operate the latter’s Sto. Niño mine. The agreement stipulated that Philex would provide funds and property, creating a “MANAGERS’ account,” and would receive 50% of the net profit before income tax as compensation. It also declared the agency as irrevocable security for Baguio Gold’s obligations to Philex. The mine incurred sustained losses, leading Philex to withdraw as manager in 1982. The parties subsequently executed a “Compromise with Dation in Payment,” where Baguio Gold acknowledged an indebtedness to Philex. Philex later wrote off a portion of this debt, amounting to P112,136,000.00, in its 1982 books and claimed it as a deduction for “bad debt” in its annual income tax return.
The Bureau of Internal Revenue disallowed the deduction and issued a deficiency income tax assessment. Philex protested, arguing the amount represented a valid bad debt loss. The Court of Tax Appeals affirmed the disallowance, a decision sustained by the Court of Appeals. The appellate court ruled that the relationship between Philex and Baguio Gold was not a creditor-debtor relationship but a partnership, making the claimed deduction invalid.

ISSUE

Whether the Court of Appeals erred in ruling that the relationship between Philex Mining and Baguio Gold was a partnership, thereby disallowing the claimed bad debt deduction.

RULING

The Supreme Court denied the petition and affirmed the assailed rulings. The legal logic rests on characterizing the true nature of the agreement between the parties. Despite being denominated as a “Power of Attorney,” the contractual provisions established a partnership, not a mere agency or creditor-debtor arrangement. The agreement stipulated profit-sharing, with Philex receiving 50% of the net profit, which is prima facie evidence of a partnership under Article 1769 of the Civil Code. Furthermore, Philex contributed funds and property to a common fund, co-owned the assets (“MANAGERS’ account” and “owner’s account”), and the agency was made irrevocable as security for mutual obligations, all indicative of a partnership’s essence of affecting third persons.
Consequently, the claimed deduction for a bad debt was properly disallowed. A bad debt deduction under tax law presupposes a valid and existing creditor-debtor relationship. Since the advances were not loans but contributions to a partnership’s common fund, their write-off constituted a loss from the partnership’s dissolution and settlement, not a bad debt arising from a debtor’s insolvency. Such a loss is not deductible in the same manner as a bad debt. Therefore, Philex’s deficiency income tax assessment was valid.
