G.R. No. 161759 - Commissioner of Customs vs. Oilink International Corp.

Union Refinery Corporation (URC) was established on September 15, 1966, under the Corporation Code of the Philippines and undertook the importation of oil products, notably from 1991 to 1994.
Oilink International Corporation (Oilink) was incorporated on January 11, 1996 with the primary purpose of manufacturing, importing, exporting, buying, selling, or dealing in oil, gas, and their by-products.
URC and Oilink shared interlocking directors; evidence of URC’s full ownership of Oilink was provided in a January 15, 1996 letter from Esther Magleo, URC’s Vice-President and General Manager.

Tax demands began when Oscar Brillo, the District Collector of the Port of Manila, issued a formal demand on March 4, 1998, requiring URC to pay taxes and duties on oil imports (from January 6, 1991 to November 7, 1995).
Subsequent demand letters were issued:

On April 16, 1998, a reduced demand of P289,287,486.60 for Value-Added Taxes (VAT), special duties, and excise taxes was communicated.
On November 25, 1998, Commissioner Pedro C. Mendoza directed URC to pay P119,223,541.71 in taxes for 17 oil shipments.
On December 21, 1998, a further reduced demand of P99,216,580.10 was communicated.
On December 23, 1998, Commissioner Nelson Tan, upon assuming office, affirmed the P99,216,580.10 assessment.

URC, represented by its counsel and officials, challenged these demands by seeking detailed computations and arguing inconsistencies.

On January 18, 1999, URC, through Magleo, contested the demanded amount, proposing instead to pay only P28,933,079.20 by compromise.
The controversy escalated when, on July 2, 1999, Commissioner Tan issued a final demand for a total liability of P138,060,200.49 against both URC and Oilink.
Oilink formally protested the assessment on July 8, 1999, arguing that it was not the proper party liable for the deficiency taxes and duties.
Following detailed correspondence, on July 12, 1999, Commissioner Tan provided a detailed computation and emphasized that Oilink’s clearance was contingent on payment of the assessment and performance of additional security measures.

Oilink sought judicial relief by appealing to the Court of Tax Appeals (CTA) on July 30, 1999, challenging the legality of the demand, arguing it was issued without proper authority and constituted an abuse of discretion.
On July 9, 2001, the CTA declared the assessment against Oilink null and void.
A subsequent motion for reconsideration by the Commissioner of Customs was denied by the CTA.
The Commissioner of Customs then elevated the case to the Court of Appeals (CA), raising issues on jurisdiction, the cause of action, and the propriety of piercing the corporate veil to impute liability to Oilink.

Whether the CTA had jurisdiction over the subject matter concerning the demand for deficiency taxes and duties as imposed by the Commissioner of Customs.
Whether the appeal was timely, considering the proper reckoning date based on the denial of the protest and not the earlier administrative demand letters.

Whether Oilink had a valid cause of action when contesting the final demand issued on July 2, 1999.
Whether the administrative remedies, particularly the requirement to pay under protest, were appropriately exhausted or whether immediate judicial recourse was justified.

Whether the Commissioner of Customs could legally pierce the corporate veil to treat Oilink as the mere alter ego of URC.
Whether there was sufficient evidence to show that Oilink was organized solely to avoid tax obligations, defeat public convenience, justify wrong, protect fraud, or circumvent legal provisions.
