G.R. No. L-11776 - Gonzales vs. Go Tiong

Petitioners: Hon. Paquito N. Ochoa, Jr. (Executive Secretary), Hon. Rozanno Rufino B. Biazon (Commissioner of the Bureau of Customs, BOC), and Atty. Juan Lorenzo T. TaAada (Deputy Commissioner of BOC).
Respondent: Atty. Christopher S. Dy Buco, member of the Run-After-The-Smugglers (RATS) Group of the BOC.
Sanyo Seiki Stainless Steel Corporation also filed a related petition.

On June 30, 2011, then BOC Commissioner Alvarez issued four Letters of Authority (LOAs) and four Mission Orders directed at warehouses of Sanyo Seiki and other entities in Bulacan and Malabon.
The LOAs and Mission Orders authorized the RATS Group to enforce Section 2536 of the Tariff and Customs Code by demanding evidence of payment of duties and taxes on foreign articles.
The RATS Group, including Atty. Dy Buco, requested police assistance to implement these LOAs and Mission Orders.
At the Bulacan warehouse, the RATS Group was denied entry and asked to wait for a legal representative, who arrived after they left. The group then stationed themselves nearby.
At the Malabon warehouses, attempts to serve LOAs and Mission Orders were similarly denied.

On July 9, 2011, Acosta of the RATS Group intercepted a delivery truck leaving the Bulacan warehouse, demanded evidence of duties and taxes payment, but was presented only local receipts.
The truck and its cargo of stainless steel products were seized via a Warrant of Seizure and Detention.
Sanyo Seiki’s legal counsel presented a sales invoice showing the products were locally purchased from Speedwealth Commercial Company (SCC). However, SCC was not an accredited importer according to BOC records.
Sanyo Seiki filed a complaint with the Office of the President (OP) against Atty. Dy Buco and others for grave misconduct and related charges.

The OP, under Executive Secretary Paquito N. Ochoa, Jr., formally charged Atty. Dy Buco and other RATS Group members with Grave Misconduct, Grave Abuse of Authority and Oppression, Gross Incompetence and Inefficiency, and Conduct Prejudicial to the Best Interest of the Service.
The OP found them guilty, imposed the penalty of dismissal from service with accessory penalties, and terminated the temporary appointment of Deputy Commissioner Chavez.

Atty. Dy Buco appealed to the Court of Appeals (CA), which reversed and set aside the OP Decision, dismissing the complaint against him and ordering his reinstatement with back pay.
Petitioners, including the OP and BOC officials, filed petitions for review before the Supreme Court (SC).
Sanyo Seiki also filed a petition challenging the dismissal of charges against Atty. Dy Buco.

Whether Sanyo Seiki, as a private complainant and not a respondent in the administrative case, has the legal personality or standing to appeal the CA decision.

Whether the OP, through its officials, has the legal interest and authority to appeal the CA decision.
