G.R. No. 202534 - Commissioner of Internal Revenue vs. Semirara Mining Corp.

Petitioner: Commissioner of Internal Revenue (CIR), the government official authorized to determine, approve, and process applications for tax refunds or issuance of Tax Credit Certificates (TCC).
Respondent: Semirara Mining Corporation (SMC), a domestic corporation engaged in the exploration, extraction, and sale of coal products, operating a coal mine in Semirara, Caluya, Antique.
Transaction: SMC sold its coal production to the National Power Corporation (NPC) under a duly executed Coal Supply Agreement.

On July 11, 1977, the predecessors of SMC entered into a COC with the government, executed through the Energy Development Board under Presidential Decree (PD) No. 972.
PD No. 972 provided various incentives to the operators, including an exemption from all taxes except income tax.
The tax exemption was expressly included in the contract under Section 5.2, granting SMC the benefit of exemption from all national and local taxes except income tax.

SMC maintained that Section 109 of Republic Act (R.A.) No. 8424 (as contained in the National Internal Revenue Code of 1997) exempted it from Value Added Tax (VAT) on its sales or importation of coal.
Subsequent Amendment: With the amendment under R.A. No. 9337, although adjustments were made in the tax code, the essential VAT exemption for SMC remained under Section 109(K) of the amended law.

NPC, in accordance with its revised practice following R.A. No. 9337, withheld 5% final VAT on SMC’s coal billings.
Specifically, on February 9, 2007, NPC remitted to the Bureau of Internal Revenue (BIR) a total of P15,292,054.93 representing the final VAT withheld on SMC’s January 2007 coal sales.

SMC requested clarity from the BIR regarding its VAT-exempt status, which led to the issuance of BIR Ruling No. 0006-2007 confirming the VAT exemption.
On May 21, 2007, SMC filed an Application for Tax Credits/Refunds at Revenue District Office (RDO) No. 121 for the amount withheld.
Due to an alleged delay or inaction by the tax authorities, SMC later filed a Petition for Review with the Court of Tax Appeals (CTA) Division on February 4, 2009.

On January 4, 2011, the CTA Division granted SMC’s claim by directing the refund or issuance of a Tax Credit Certificate amounting to P15,292,054.91 corresponding to the final VAT withheld for January 2007.
The Division found that SMC’s sales of coal for that period were tax-exempt under Section 109(K) of the amended NIRC in relation to Section 16 of PD No. 972.

Petitioner CIR filed a Motion for Reconsideration which was denied.
Following the denial, CIR elevated the matter by filing a Petition for Review before the CTA En Banc.
The CTA En Banc, on March 22, 2012, affirmed the decision of the CTA Division and also denied a subsequent Resolution dated June 28, 2012 filed by SMC for further reconsideration of the petitioner’s arguments.

The primary issue is whether the CTA erred in ruling that SMC is entitled to a tax refund (or the issuance of a Tax Credit Certificate) for the final VAT amount withheld and remitted for its coal sales in January 2007.
Related contentions include:

Whether the VAT exemption granted under PD No. 972, as implemented through Section 5.2 of the COC, continues to apply despite claims that its provisions might have been rendered inoperative or repealed by subsequent amendments under R.A. No. 9337.
Whether the administrative remedies were correctly exhausted and the petition for judicial relief was timely filed.
