Medina vs. Collector of Internal Revenue

Sales between spouses are null and void under Article 1490 of the Civil Code and may be disregarded by tax authorities, who may treat the spouse's subsequent sales as the other spouse's original taxable sales, regardless of an alleged prenuptial agreement of complete separation of property, where the evidence fails to establish the existence of such agreement and the spouses' conduct is inconsistent with its alleged terms.

Antonio Medina, a lawyer by profession, married Antonia Rodriguez on or about May 20, 1944. Before 1946, the spouses possessed neither property nor business of their own. Medina later acquired forest concessions in the municipalities of San Mariano and Palanan in the Province of Isabela, from which he cut and sold logs through his agent, Mariano Osorio. His wife began engaging in business as a lumber dealer sometime in 1949. The dispute arises from the tax treatment of logs Medina sold to his wife, who then resold them in Manila through the same agent, with proceeds either received by Osorio for Medina or deposited in Medina's current account with the Philippine National Bank. The Collector of Internal Revenue treated these inter-spouse sales as void under Article 1490 of the Civil Code and assessed deficiency sales taxes against Medina under Section 186 of the National Internal Revenue Code.

Antonio Medina, a lawyer by profession, married Antonia Rodriguez on or about May 20, 1944. Before 1946, the spouses had neither property nor business of their own. Medina subsequently acquired forest concessions in the municipalities of San Mariano and Palanan in the Province of Isabela. From 1946 to 1948, the logs cut and removed from his concessions were sold to different persons in Manila through his agent, Mariano Osorio.

Sometime in 1949, Antonia Medina began engaging in business as a lumber dealer. From then until around 1952, Medina sold to his wife almost all the logs produced from his San Mariano concession. Mrs. Medina, in turn, sold the logs in Manila through the same agent, Mariano Osorio. The proceeds from these sales were, upon Medina's instructions, either received by Osorio for Medina or deposited by Osorio in Medina's current account with the Philippine National Bank.

On September 26, 1953, the Collector of Internal Revenue issued a tax assessment premised on the theory that the sales made by Medina to his wife were null and void under Article 1490 of the Civil Code (formerly Article 1458 of the Civil Code of 1889), which prohibits sales between spouses. Accordingly, the Collector treated the sales made by Mrs. Medina as Medina's original taxable sales under Section 186 of the National Internal Revenue Code, imposing a deficiency sales tax assessment of P4,553.54 for the period 1949 to 1952, plus an additional P643.94 based on quarterly returns from 1946 to 1952. Medina protested on November 30, 1953, but the Collector insisted.

On July 9, 1954, Medina filed a petition for reconsideration, revealing for the first time the existence of an alleged premarital agreement of complete separation of property between him and his wife, and contending that the assessments for 1946 to 1952 had already prescribed. After one hearing, the Conference Staff of the Bureau of Internal Revenue eliminated the 50% fraud penalty and held that taxes assessed before 1948 had prescribed. The Collector then issued a modified assessment demanding P3,325.68, computed as 5% sales tax on taxable amounts from 1949 to 1952 totaling P2,602.02, plus a 25% surcharge of P650.51, plus short taxes per quarterly returns for the third quarter of 1950 amounting to P58.52 with a 25% surcharge of P14.63. Medina again sought reconsideration, but the Collector denied it on April 4, 1955. Medina appealed to the Court of Tax Appeals, which upheld the assessment except for the compromise penalties. The Tax Court found that no premarital agreement of absolute separation of property existed between the spouses and, alternatively, that even if such agreement existed, the sales in question were fictitious, simulated, and not bona fide.

• Existence of Prenuptial Agreement: Petitioner maintained that he and his wife executed and recorded a prenuptial agreement for a regime of complete separation of property before their marriage, and that all trace of the document was lost on account of the war, imputing lack of basis for the Tax Court's factual finding that no such agreement was ever executed.
• Inapplicability of Article 1490: Petitioner argued that the prohibition on sales between spouses under Article 1490 of the Civil Code does not apply to the sales made to his wife because such transactions are contemplated and allowed by Articles 7 and 10 of the Code of Commerce.
• Collector Lacks Standing to Question Sales: Petitioner contended that the Collector of Internal Revenue, being a stranger to the transactions, cannot assail the validity of the questioned sales.
• Illegally Seized Evidence: Petitioner asserted that the lower court erred in using illegally seized documentary evidence against him.
• Prescription: Petitioner contended that the assessment for the years 1946 to 1952 had already prescribed.

• Government as Interested Party: Respondent argued that the government is always an interested party to all matters involving taxable transactions and is qualified to question the validity or legitimacy of such transactions whenever necessary to block tax evasion.
• Authority to Examine Books: Respondent maintained, citing Sections 3, 9, 337, and 338 of the Tax Code, Revenue Regulations No. V-1, and the Court's ruling in U.S. vs. Aviado, that internal revenue officers and agents could require the production of books of accounts and other records from a taxpayer.
• Admissibility of Illegally Obtained Documents: Respondent relied on the settled doctrine that illegally obtained documents and papers are admissible in evidence if found competent and relevant to the case.
• Denial of Illegal Seizure: Respondent vehemently denied petitioner's imputation that documents were illegally seized.

• Validity of Inter-Spouse Sales for Tax Purposes: Whether the sales made by petitioner to his wife could be considered as his original taxable sales under Section 186 of the National Internal Revenue Code, given the prohibition in Article 1490 of the Civil Code.
• Existence of Prenuptial Agreement: Whether a premarital agreement of complete separation of property existed between the spouses, such as would remove the sales from the prohibition of Article 1490.
• Effect of Code of Commerce Provisions: Whether Articles 7 and 10 of the Code of Commerce constitute an exception to the prohibitory provisions of Article 1490 of the Civil Code against sales between spouses.
• Standing of the Collector: Whether the Collector of Internal Revenue, as a stranger to the transactions, may question the validity of the sales.
• Admissibility of Illegally Obtained Evidence: Whether documents allegedly illegally seized may be admitted in evidence in tax proceedings.

• Validity of Inter-Spouse Sales for Tax Purposes: Yes. The sales made by petitioner to his wife were correctly disregarded as void under Article 1490, and the wife's subsequent sales were properly treated as the petitioner's original taxable sales under Section 186 of the National Internal Revenue Code.
• Existence of Prenuptial Agreement: No. No premarital agreement of complete separation of property was proven to exist, the evidence being riddled with material inconsistencies, circumstantially implausible, and contradicted by the spouses' own conduct.
• Effect of Code of Commerce Provisions: No. Articles 7 and 10 of the Code of Commerce merely establish a presumption that the wife is authorized to engage in business with strangers; they do not constitute exceptions to the prohibitory provisions of Article 1490 against sales between spouses.
• Standing of the Collector: No. The government is always an interested party to all matters involving taxable transactions and is qualified to question their validity or legitimacy whenever necessary to block tax evasion.
• Admissibility of Illegally Obtained Evidence: Yes. Illegally obtained documents and papers are admissible in evidence if found competent and relevant to the case.

• Validity of Inter-Spouse Sales for Tax Purposes: Contracts violative of Article 1490 of the Civil Code are null and void, as established in Uy Sui Pin vs. Cantollas and Uy Coque vs. Sioca. Being void transactions, the sales made by Medina to his wife were correctly disregarded by the Collector, who instead treated the wife's sales through the spouses' common agent, Mariano Osorio, as Medina's original taxable sales under Section 186 of the National Internal Revenue Code. The Court of Tax Appeals committed no error in upholding this approach.

• Existence of Prenuptial Agreement: The Court found the evidence for the alleged prenuptial agreement insufficient and unreliable. First, material inconsistencies in the testimony of petitioner's witnesses undermined their credibility, and the trial court's assessment of witness credibility deserves serious consideration. Second, at the time of marriage, the spouses had neither property nor business, negating any motive to execute a property separation agreement. Third, the claim that the agreement was recorded in the Registry of Property three months before the marriage was "patently absurd," since a prenuptial agreement cannot be effective before the marriage is celebrated and would be automatically cancelled if the union did not proceed. Fourth, the spouses did not act in accordance with the alleged covenants — ownership, usufruct, and administration of their properties and business remained in the husband, and the proceeds from the wife's lumber dealings were received by Osorio for Medina or deposited in Medina's bank account. Fifth, although Medina, a lawyer, was informed in September 1953 that Article 1490 was the basis for disregarding the sales, he did not allege the existence of the separation agreement until July 1954. Finally, the Day Book of the Register of Deeds, which survived the war, did not show the document was recorded. Applying the best evidence rule, the Court upheld the trial court's decision to give little or no credence to secondary evidence of the alleged document, since not every copy — particularly the one allegedly filed with the Clerk of Court of Isabela — was accounted for as lost.

• Effect of Code of Commerce Provisions: Articles 7 and 10 of the Code of Commerce merely state, under certain conditions, a presumption that the wife is authorized to engage in business and define the incidents that flow therefrom. However, the transactions permitted are those entered into with strangers, and do not constitute exceptions to the prohibitory provisions of Article 1490 against sales between spouses. The Code of Commerce provisions do not override or carve out exceptions to the Civil Code's express prohibition.

• Standing of the Collector: The contention that the Collector, as a stranger to the transactions, cannot assail the sales is untenable. The government is always an interested party to all matters involving taxable transactions and is qualified to question their validity or legitimacy whenever necessary to block tax evasion. The Tax Court correctly so held.

• Admissibility of Illegally Obtained Evidence: Even assuming arguendo the truth of petitioner's charge regarding the seizure, it is settled in this jurisdiction that illegally obtained documents and papers are admissible in evidence if found competent and relevant to the case, citing Wong & Lee vs. Collector of Internal Revenue. The Collector also vehemently denied the imputation of illegal seizure and maintained, citing Sections 3, 9, 337, and 338 of the Tax Code, Revenue Regulations No. V-1, and U.S. vs. Aviado, that internal revenue officers could require the production of books of accounts and other records from a taxpayer.

• Prohibition on Sales Between Spouses (Article 1490, Civil Code) — Sales between spouses are null and void. This prohibition applies regardless of the property regime, unless a valid prenuptial agreement of complete separation of property is proven. Contracts violating this prohibition are void ab initio and may be disregarded by tax authorities in determining taxable sales. The Court applied this doctrine by treating the wife's resale of logs as the husband's original taxable sales, since the inter-spouse sales were void.

• Void Contracts Disregarded for Tax Purposes — Transactions that are null and void under the Civil Code produce no legal effect and cannot be recognized for tax purposes. Tax authorities may look through void transactions to determine the true taxable event. The Collector correctly disregarded the void inter-spouse sales and assessed tax on the actual taxable sales made by the wife through the common agent.

• Best Evidence Rule — Where the original document is alleged to have been lost, secondary evidence of its due execution and contents is inadmissible unless every copy is accounted for as lost. The Court upheld the trial court's refusal to give credence to secondary evidence of the alleged prenuptial agreement because not every copy — particularly the one allegedly filed with the Clerk of Court of Isabela — was accounted for as lost.

• Deference to Trial Court on Witness Credibility — When the credibility of witnesses is at issue, the trial court's judgment as to their degree of credence deserves serious consideration by the Supreme Court. This is especially true where secondary evidence is offered and the original document is not properly accounted for as lost.

• Admissibility of Illegally Obtained Evidence (Majority View) — Illegally obtained documents and papers are admissible in evidence if they are found to be competent and relevant to the case. This doctrine, as stated in Wong & Lee vs. Collector of Internal Revenue, was applied by the majority, though Justice Concepcion concurred only in the result and expressly disagreed with this proposition.

• Government as Interested Party in Taxable Transactions — The government is always an interested party to all matters involving taxable transactions and is qualified to question the validity or legitimacy of such transactions whenever necessary to prevent tax evasion. A taxpayer cannot shield void transactions from tax scrutiny on the ground that the taxing authority is a stranger to the contract.

• "Contracts violative of the provisions of Article 1490 of the Civil Code are null and void (Uy Sui Pin vs. Cantollas, 70 Phil. 55; Uy Coque vs. Sioca 45 Phil. 43). Being void transactions, the sales made by the petitioner to his wife were correctly disregarded by the Collector in his tax assessments that considered as the taxable sales those made by the wife through the spouses' common agent, Mariano Osorio." — This passage states the ratio decidendi: void inter-spouse sales are disregarded for tax purposes, and the wife's sales are treated as the husband's original taxable sales.

• "The government, as correctly pointed out by the Tax Court, is always an interested party to all matters involving taxable transactions and, needless to say, qualified to question their validity or legitimacy whenever necessary to block tax evasion." — This defines the doctrine that the government has standing to challenge the validity of transactions for tax purposes, preventing taxpayers from invoking the stranger-to-contract rule against tax authorities.

• "But said provisions merely state, under certain conditions, a presumption that the wife is authorized to engage in business and for the incidents that flow therefrom when she so engages therein. But the transactions permitted are those entered into with strangers, and do not constitute exceptions to the prohibitory provisions of Article 1490 against sales between spouses." — This clarifies the limited scope of Articles 7 and 10 of the Code of Commerce and confirms that they do not override Article 1490's prohibition on inter-spouse sales.

• "it is now settled in this jurisdiction that illegally obtained documents and papers are admissible in evidence, if they are found to be competent and relevant to the case" — This states the majority's rule on admissibility of illegally obtained evidence, a proposition that Justice Concepcion expressly disagreed with in his concurring opinion.

• Collector vs. Bautista, G.R. Nos. L-12250 & L-12259, May 27, 1959 — Followed. The Court relied on this case for the principle that the trial court's assessment of witness credibility deserves serious consideration on appeal.
• Wong & Lee vs. Collector of Internal Revenue, G.R. No. L-10155, August 30, 1958 — Followed. Cited as authority for the doctrine that illegally obtained documents and papers are admissible in evidence if competent and relevant.
• Uy Sui Pin vs. Cantollas, 70 Phil. 55 — Followed. Cited for the proposition that contracts violative of Article 1490 of the Civil Code are null and void.
• Uy Coque vs. Sioca, 45 Phil. 43 — Followed. Cited jointly with Uy Sui Pin for the same proposition regarding the nullity of contracts violating Article 1490.
• U.S. vs. Aviado, 38 Phil. 10 — Followed. Cited by the Collector for the authority of internal revenue officers to require the production of books of accounts and other records from a taxpayer.

• Article 1490, Civil Code of the Philippines (formerly Article 1458, Civil Code of 1889) — Prohibits sales between spouses. The Court held that sales made by Medina to his wife were null and void under this provision and were correctly disregarded for tax assessment purposes.
• Section 186, National Internal Revenue Code — Governs the imposition of sales tax on original sales. The Collector applied this provision by treating the wife's resales as the husband's original taxable sales, since the inter-spouse sales were void.
• Articles 7 and 10, Code of Commerce — Establish a presumption that the wife is authorized to engage in business and define the incidents flowing therefrom. The Court held these provisions apply only to transactions with strangers and do not constitute exceptions to Article 1490's prohibition on inter-spouse sales.
• Sections 3, 9, 337, and 338, National Internal Revenue Code (Tax Code) — Confer authority on internal revenue officers and agents to require the production of books of accounts and other records from a taxpayer. The Collector cited these provisions to support his authority to examine the petitioner's records.
• Revenue Regulations No. V-1 — Pertinent revenue regulations cited by the Collector in support of the authority to require production of taxpayer records.

Padilla, Bautista Angelo, Labrador, Barrera, Gutierrez David, and Dizon, JJ., concurred.

Concepcion, J., concurred in the result but expressly disagreed with the majority's view that illegally obtained documents and papers are admissible in evidence if competent and relevant. He cited Weeks vs. United States (232 US 383) and Elkins vs. United States (4 L. ed. 1669), arguing that the protection against unreasonable searches and seizures should not be sacrificed to obtain convictions, and that evidence obtained through unlawful seizures should not receive judicial sanction.
