Republic vs. Sandiganbayan

The State, by commencing litigation, impliedly waives its sovereign immunity and becomes subject to the same procedural rules as a private litigant, including the obligation to comply with modes of discovery such as interrogatories and production of documents.

The PCGG, acting for the Republic, filed Civil Case No. 0008 before the Sandiganbayan against several defendants, including Bienvenido R. Tantoco, Jr. and Dominador R. Santiago, for the recovery of alleged ill-gotten wealth. After the defendants filed an answer, they sought discovery by serving amended interrogatories on the PCGG and filing a motion for production and inspection of documents. The Sandiganbayan admitted the interrogatories and granted the motion. The PCGG challenged these resolutions, arguing the interrogatories were improper and the documents were privileged.

• Nature of the Action: The PCGG filed a civil complaint against private respondents and others for "reconveyance, reversion, accounting, restitution and damages" based on alleged ill-gotten wealth.
• Discovery Proceedings: After filing their answer, private respondents served amended interrogatories on the PCGG and moved for production and inspection of documents. The interrogatories sought specific details about the properties and acts attributed to them in the complaint. The motion sought production of documents forming the basis of the complaint's verification and those listed in the PCGG's pre-trial brief.
• Sandiganbayan's Rulings: The Sandiganbayan admitted the interrogatories and granted the production motion, finding them relevant and proper for discovery.
• PCGG's Objections: The PCGG argued the interrogatories were addressed to the PCGG as an entity without naming a specific officer, dealt with matters reserved for trial, and would violate the immunity of PCGG commissioners under Executive Order No. 1. It also claimed the documents were privileged, already marked as exhibits, or non-existent.

• Defective Interrogatories: Petitioner argued the interrogatories were defective because they were addressed to the PCGG generally without naming a specific officer competent to answer, and that they sought the same particulars previously denied in a motion for bill of particulars.
• Premature and Improper: Petitioner contended the interrogatories delved into evidentiary matters that were part of the proof at trial, making them premature and essentially a deposition without leave of court.
• Privilege and Immunity: Petitioner maintained that compelling PCGG commissioners to answer would violate the immunity from testifying or producing evidence granted under Section 4 of Executive Order No. 1, and that the documents sought were privileged or confidential.

• Proper Discovery Tool: Respondents countered that interrogatories are a proper mode of discovery under Rule 25 and are not limited to ultimate facts but extend to evidentiary matters to avoid surprise at trial.
• Waiver of Immunity: Respondents argued that by initiating the lawsuit, the PCGG waived any sovereign immunity and subjected itself to the same procedural rules as any other litigant, including discovery.
• Relevance and Good Cause: Respondents asserted the interrogatories were specific and relevant to the allegations in the complaint, and that good cause existed for the production of documents, as they were the basis of the complaint's verification and intended exhibits.

• Scope of Discovery: Whether the amended interrogatories served on the PCGG were proper under the Rules of Court, considering they were addressed to a government commission and sought evidentiary details.
• State Immunity: Whether the PCGG and its commissioners are immune from discovery proceedings by virtue of Executive Order No. 1 and the principle of state immunity from suit.
• Production of Documents: Whether the Sandiganbayan gravely abused its discretion in ordering the production and inspection of documents in the PCGG's possession.

• Scope of Discovery: The interrogatories were proper. Under Rule 25, interrogatories addressed to a juridical entity like the PCGG are to be answered by any officer competent to testify on its behalf. The purpose of discovery is to ascertain all relevant facts, both ultimate and evidentiary, before trial. The PCGG's objections regarding specificity and similarity to a bill of particulars were unavailing, as discovery has a broader scope.
• State Immunity: The PCGG is not immune from discovery in a case it initiated. By filing the complaint, the State impliedly waives its sovereign immunity and becomes subject to the court's processes and procedural rules, including discovery. The immunity granted to PCGG members under Executive Order No. 1 does not apply to a judicial proceeding the PCGG itself commenced, as filing suit entails a waiver of such exemption.
• Production of Documents: Good cause was shown. The documents were relevant as they formed the basis of the complaint's allegations and were intended as exhibits. The PCGG's claims of privilege or non-existence could be raised in its response, but did not justify a blanket refusal to comply with the discovery order.

• Waiver of State Immunity by Instituting Suit — When the State initiates litigation, it divests itself of its sovereign character and sheds its immunity from suit, descending to the level of an ordinary litigant. It thereby subjects itself to the court's jurisdiction and the applicable procedural rules, including the rights and duties under the rules of discovery.
• Liberal Construction of Discovery Rules — The deposition-discovery rules are to be accorded a broad and liberal treatment. Their purpose is to enable parties to obtain the fullest possible knowledge of the issues and facts before trial, thereby preventing trials from being carried on in the dark. "Fishing expeditions" are permitted through discovery to compel mutual disclosure of all relevant facts.

• "The consent of the State to be sued may be given expressly or impliedly. Express consent may be manifested either through a general law or a special law. Implied consent is given when the State itself commences litigation or when it enters into a contract." — This passage articulates the principle of implied waiver of state immunity by the act of filing suit.
• "The deposition-discovery rules are to be accorded a broad and liberal treatment. No longer can the time-honored cry of 'fishing expedition' serve to preclude a party from inquiring into the facts underlying his opponent's case. Mutual knowledge of all the relevant facts gathered by both parties is essential to proper litigation." — This excerpt underscores the policy behind the liberal application of discovery rules.

• Alonso v. Villamor, 16 Phil. 315 (1910) — Cited for the principle that litigation is not a game of technicalities and each party must fully and fairly lay before the court the facts in issue.
• Froilan v. Pan Oriental Shipping Co., 95 Phil. 905 — Cited for the rule that when the State initiates an action, it surrenders its privileged position and comes down to the level of the defendant, who may assert counterclaims.
• Ministerio v. City of Cebu, 40 SCRA 464 — Cited for the ruling that the defense of state immunity cannot be set up against an action for payment of just compensation in an expropriation case.

• Section 1, Rule 25, Rules of Court — Provides that interrogatories may be served upon a party without leave of court after an answer has been served. If the party is a juridical entity, they shall be answered by any officer competent to testify in its behalf.
• Section 4, Executive Order No. 1 (1986) — Grants immunity to PCGG members from civil actions for anything done in the discharge of their tasks and from being required to testify or produce evidence in judicial proceedings concerning matters within its official cognizance. The Court held this immunity is waived when the PCGG itself initiates the suit.

• Justice Isagani A. Cruz — Issued a concurring opinion, applauding the ponencia for educating the bar on the intricacies of discovery and agreeing with the conclusion that the PCGG, having filed the suit, could not claim immunity from discovery.
