Siain Enterprises, Inc. vs. Cupertino Realty Corp.

The presumption of sufficient consideration for negotiable instruments and contracts under Rule 131, Section 3 and the Negotiable Instruments Law Section 24 is a disputable presumption that shifts the burden to the party denying receipt; mere bare denial without affirmative evidence cannot overcome this presumption. Furthermore, the doctrine of piercing the veil of corporate fiction applies when a corporation is merely the alter ego of its stockholders or another corporation, characterized by oneness of operations, common control, and unity in corporate records, and may be invoked to prevent the use of the corporate fiction to evade valid obligations.

The dispute arose from a complex financing arrangement between Siain Enterprises and Cupertino Realty Corp. involving multiple loan documents, amendments, and allegations of non-receipt of loan proceeds. The case highlights the conflict between formal loan documentation (promissory notes and mortgages) and subsequent claims of contractual failure or absence of consideration.

• Filed in RTC, Branch 29, Iloilo City (Civil Case No. 23244)
• RTC Decision: Dismissed Siain's complaint; ordered payment of damages to Cupertino; upheld validity of amended REM; recalled previous order nullifying foreclosure.
• Appealed to CA (CA-G.R. CV No. 71424)
• CA Decision: Affirmed RTC ruling.
• Elevated to SC via Petition for Review on Certiorari under Rule 45.

• April 10, 1995: Siain obtained a P37M loan from Cupertino, evidenced by a promissory note and secured by a real estate mortgage (REM) over two parcels of land and equipment. The note authorized escrow of proceeds with Metropolitan Bank to pay off Siain's DBP loan.
• April 12, 1995: Parties executed an amendment to the promissory note setting 17% interest per annum.
• August 16, 1995: Cua Le Leng (Siain's President) signed a second promissory note for P160M as maker for Siain and co-maker in her personal capacity. Note carried 30% compounding interest and required execution of additional security.
• August 16, 1995: Parties executed an Amendment of Real Estate Mortgage increasing the secured loan from P37M to P197M, confirming all other terms of the original REM.
• March 11 & May 17, 1996: Siain demanded release of the P160M loan proceeds, claiming non-receipt.
• Cupertino's Response: Denied non-release; claimed P160M represented total amounts previously given to Siain and its affiliates (Yuyek Manufacturing Corp., Siain Transport, Inc.) and personal transactions of Cua Le Leng and her common-law husband Alberto Lim through checks, debit memos, pledges of jewelry, trucks, and condominiums.
• Foreclosure: Cupertino instituted extrajudicial foreclosure proceedings with respondent Notary Public Edwin R. Catacutan commissioned to conduct the auction sale scheduled for October 11, 1996.
• Siain's Action: Filed complaint to enjoin foreclosure, claiming the amended REM was void for lack of consideration (non-receipt of P160M) and that foreclosure was improper.

• The amended real estate mortgage is void because Siain never received the P160M loan increase that served as its consideration.
• The P160M promissory note does not accurately reflect the agreement; proceeds were to be released after signing but were never delivered.
• The lower courts erroneously applied the doctrine of piercing the veil of corporate fiction to attribute obligations of separate affiliate corporations (Yuyek Manufacturing, Siain Transport) to Siain Enterprises.
• The cash receipt journal showing no entry for P160M proves non-receipt.
• The parol evidence rule should exclude Cupertino's extrinsic evidence of consideration.

• The P160M was not a new release but represented consolidated prior obligations to Siain's affiliates and Cua Le Leng personally, evidenced by checks, debit memos, and pledges made over the years.
• The promissory notes and mortgage amendments, prefaced with "for value received," create a disputable presumption of consideration under the NIL and Rules of Court which Siain failed to overcome.
• Piercing the veil was proper because Siain, Yuyek, Siain Transport, and Cua Le Leng operated as alter egos (common incorporators, same address, same accountant/bookkeeper Rosemarie Ragodon, common president with unlimited control), making the fiction of separate corporate personalities a shield to evade just obligations.
• Siain's bare denial of receipt cannot prevail over affirmative evidence of consideration.
• Cupertino itself is the alter ego of Wilfredo Lua, validating pre-incorporation transactions.

• Procedural Issues: N/A
• Substantive Issues:
  • Whether the amended real estate mortgage is void for lack of consideration where the mortgagor claims non-receipt of the loan proceeds.
  • Whether the lower courts properly applied the doctrine of piercing the veil of corporate fiction to hold petitioner liable for transactions entered into by its affiliate corporations and president.

• Procedural: N/A
• Substantive:
  • No, the amended REM is valid. The presumption of sufficient consideration under Rule 131, Section 3(r) and (s) and NIL Section 24 applies to the promissory notes and mortgage. Siain, as plaintiff, carried the burden of proof to establish by preponderance of evidence that no consideration existed. Its evidence consisting solely of bare denial of receipt and an incomplete cash journal (covering only 1995 when transactions occurred earlier) failed to overcome the disputable presumption. As between negative evidence of denial and affirmative evidence of consideration, the latter prevails.
  • Yes, piercing the veil was proper. The SC affirmed that Siain Enterprises, Yuyek Manufacturing Corp., and Siain Transport, Inc. were mere alter egos of Cua Le Leng, characterized by: (1) common incorporators, stockholders, and board of directors; (2) same internal bookkeeper/accountant; (3) same office address; (4) same majority stockholder and president (Cua Le Leng) with unlimited authority to use funds interchangeably. The corporate fiction was used to defeat public convenience and evade payment of a valid obligation, justifying piercing. The same principle applied to Cupertino as alter ego of Wilfredo Lua validated prior transactions.

• Piercing the Veil of Corporate Fiction — While a corporation has a juridical personality separate from its stockholders (Corporation Code, Sec. 2; Civil Code, Art. 44), this fiction may be disregarded when used to defeat public convenience, justify wrong, protect fraud, or defend crime, or when the corporation is merely the alter ego or instrumentality of another entity or person. Requisites for application (Alter Ego Test): (1) Control, not merely majority stock ownership, but complete domination of finances, policies, and business practices; (2) such control must have been used to commit fraud or wrong, or to perpetrate violation of statutory or contractual duty; (3) the breach of duty must have proximately caused the loss complained of. In this case, the SC found "oneness of operations" and "unity of interest" where Cua Leleng controlled Siain and affiliates with identical operations and accounting, using them interchangeably to obtain loans, making piercing necessary to prevent injustice and evasion of the P160M obligation.
• Presumption of Consideration — Under Rule 131, Section 3(r) and (s) of the Rules of Court and Section 24 of the Negotiable Instruments Law (Act 2031), there is a disputable presumption that a contract or negotiable instrument was given or indorsed for sufficient consideration. This presumption is satisfactory if uncontradicted. The party challenging the instrument bears the burden of overcoming this presumption by competent evidence, not mere denial.

• "As a general rule, a corporation will be deemed a separate legal entity until sufficient reason to the contrary appears. But the rule is not absolute. A corporation's separate and distinct legal personality may be disregarded and the veil of corporate fiction pierced when the notion of legal entity is used to defeat public convenience, justify wrong, protect fraud, or defend crime."
• "It is a basic axiom in this jurisdiction that as between the plaintiff's negative evidence of denial and the defendant's affirmative evidence on the existence of the consideration, the latter must be given more weight and value."
• "[Petitioner] corporation, Yuyek and Siain Transport are characterized by oneness of operations vested in the person of their common president, Cua Le Leng, and unity in the keeping and maintenance of their corporate books and records through their common accountant and bookkeeper... these corporations are proven to be the mere alter-ego of their president Cua Le Leng."

• United States v. Milwaukee Refrigerator Transit Co. — Cited as foundational authority for the doctrine of piercing the corporate veil.
• Titan Construction Corporation v. Uni-Field Enterprises, Inc. and Sigaya v. Mayuga — Cited for the rule that factual findings of the trial court, when affirmed by the CA, are accorded the highest degree of respect and are binding on the SC absent grave errors.
• Ilao-Quianay v. Mapile and Child Learning Center, Inc. v. Tagorio — Cited for the exceptions allowing the SC to review factual findings (grounded on speculation, manifestly mistaken inferences, grave abuse of discretion, etc.).

• Rule 131, Section 3(r) and (s), Rules of Court — Disputable presumptions that there was sufficient consideration for a contract and that a negotiable instrument was given for sufficient consideration.
• Section 24, Negotiable Instruments Law (Act 2031) — Presumption of consideration for negotiable instruments.
• Section 2, Corporation Code (B.P. Blg. 68) — Corporation as a separate legal entity.
• Article 44, Civil Code — Juridical capacity of corporations.
