Legal question
Can a Senate impeachment court subpoena and open a respondent's bank deposits and income tax returns, and what does Philippine law require before those records can lawfully be examined?
Applicable laws and rules
- Republic Act No. 1405 (Secrecy of Bank Deposits Act, 1955), Section 2 — expressly excepts "cases of impeachment"
- Republic Act No. 6426 (Foreign Currency Deposit Act), Section 8, as amended by Presidential Decree No. 1246 — absolute confidentiality, only the depositor's written permission
- National Internal Revenue Code of 1997 (RA 8424), Section 71 — inspection of income tax returns upon order of the President
- National Internal Revenue Code of 1997, Section 270 — penalizes unlawful divulgence of taxpayer information
- Republic Act No. 9160 (Anti-Money Laundering Act of 2001), as amended by RA 9194, RA 10167 and RA 11521, Section 11 — AMLC bank inquiry
- 1987 Philippine Constitution, Article XI, Section 3(6) — the Senate's sole power to try and decide impeachment cases
Why this matters
Financial records are the heart of the corruption-type Articles of Impeachment: confidential-funds misuse, unexplained wealth, and non-disclosure in the Statement of Assets, Liabilities and Net Worth. If the prosecution cannot obtain the underlying bank and tax documents, those Articles rest largely on inference. But confidentiality statutes protect every Filipino depositor and taxpayer, not just a Vice President — so how the impeachment court reads them sets a precedent reaching far beyond this trial. This is also the clearest echo of the 2012 Corona impeachment, where exactly these statutes were fought over. Knowing the rules lets you follow the July 15 arguments understanding what each side must actually establish.
Bank deposits: impeachment is an express exception
Start with the most counter-intuitive point: bank secrecy in the Philippines has an express impeachment exception, and it has had one since 1955. Section 2 of RA 1405 declares all deposits "absolutely confidential" and says they may not be examined "by any person, government official, bureau or office, except upon written permission of the depositor, or in cases of impeachment, or upon order of a competent court in cases of bribery or dereliction of duty of public officials, or in cases where the money deposited or invested is the subject matter of the litigation." Impeachment sits in the statute as its own standalone exception. It does not require a court order, and it does not require the depositor's consent. On the text, an impeachment court examining peso deposits is doing something the Bank Secrecy Law itself contemplates.
Foreign currency deposits: no impeachment exception at all
Foreign currency deposits are a different world. Section 8 of RA 6426, as amended by PD 1246, declares them "absolutely confidential" and permits examination only "upon the written permission of the depositor" — "in no instance" otherwise. It goes further, providing that such deposits are "exempt from attachment, garnishment, or any other order or process of any court, legislative body, government agency or any administrative body whatsoever." There is no impeachment exception. The phrase "legislative body" is the crucial one, because the Senate sitting as an impeachment court is exactly that. This asymmetry is not academic: in the 2012 impeachment of Chief Justice Renato Corona, the Supreme Court restrained the Senate's subpoena of his foreign currency accounts on this basis, and the peso and foreign-currency tracks diverged. Corona ultimately signed a waiver.
Tax returns: only on the President's order
Tax returns run on a third, separate track. Section 71 of the National Internal Revenue Code provides that after assessment, returns "shall constitute public records and be open to inspection as such upon the order of the President of the Philippines, under rules and regulations to be prescribed by the Secretary of Finance, upon recommendation of the Commissioner." A tax return is therefore not simply secret — it is a public record whose inspection is gated on a presidential order issued through the Department of Finance and the BIR. The alternative is the taxpayer's own written waiver. Backing this up, Section 270 makes it a crime for a BIR officer or employee to divulge taxpayer information, punishable by a fine of ₱50,000 to ₱100,000 and imprisonment of two to five years — with Section 71 named as one of its express exceptions. That penal exposure is why BIR officials do not open boxes on a subpoena alone, and why Sen. Panfilo Lacson said publicly on July 12, 2026 that he would not support opening the BIR box without written presidential authority, stating he could not join an act that violates Sections 71 and 270.
The AMLC route is not a shortcut
The Anti-Money Laundering Act is the prosecution's alternative path to bank records, and it has its own gate. Under RA 9160 as amended (notably by RA 10167 and RA 11521), the AMLC may inquire into and examine deposits, but as a general rule it must first obtain an ex parte order from the Court of Appeals upon a finding of probable cause that the deposits are related to an unlawful activity or a money laundering offense. A narrow set of predicate crimes — including kidnapping for ransom, certain drug offenses, hijacking, destructive arson and murder — may be examined without a court order. Graft and plunder are not on that no-court-order list. An AMLC subpoena therefore is not a way around the courts; it relocates the probable-cause finding to the Court of Appeals. The prosecution's renewed request asks the impeachment court to subpoena the AMLC through its chairman, Bangko Sentral ng Pilipinas Governor Eli Remolona Jr., to produce account records, transaction documents, covered transaction reports, suspicious transaction reports, and investigation records.
Trial posture as of July 13, 2026
The BIR's sealed green box first surfaced on April 22, 2026, when BIR Commissioner Charlito Martin Mendoza brought it to a House Committee on Justice hearing. The committee declined to open it and left the question to the Senate. When the trial opened, Escudero ruled the impeachment court had no lawful order authorizing it to hold the box — it had never been marked or formally offered as evidence — and it was returned to the BIR on July 7, 2026. The prosecution then moved for the impeachment court to issue its own subpoena duces tecum and ad testificandum for an expanded set of records. Prosecution lawyer Benjamin Tolosa Jr. said seeking President Marcos's authorization under Section 71 is one option under consideration — the same route taken in the Corona trial, where President Aquino authorized BIR Commissioner Kim Henares to produce records and testify. The defense argues the records were improperly obtained through a House-issued subpoena in the first place. Escudero ordered memoranda by July 13 and set oral arguments for July 15, 2026, giving each side 10 minutes plus a 3-minute rebuttal before the court decides. As of this writing the impeachment court has not ruled on any of the subpoenas. Ateneo law professor and former law dean Mel Sta. Maria has said the dispute could itself end up before the Supreme Court.
What individuals should know
The confidentiality rules described here protect ordinary depositors and taxpayers, and they are worth knowing outside the political drama. Your peso bank deposits cannot be examined by anyone — including a government agency — without your written permission or one of RA 1405's narrow exceptions, and a bank officer who discloses them faces criminal liability under Section 3 of that law. Your foreign currency deposits are protected even more strictly: under RA 6426 as amended, written depositor permission is the only route, and the deposits are exempt from court and legislative process. Your income tax return is a public record only in the specific sense Section 71 allows, meaning inspection requires a presidential order or your own waiver, and a BIR employee who leaks it commits a crime under Section 270. Two practical cautions apply to reading the news on this. First, a subpoena is a request for records, not a finding that anything is wrong with them. Second, the impeachment court has not decided any of these questions yet, so nothing about the Vice President's bank or tax records has been established. Watch the July 15 oral arguments for how the court reads the "in cases of impeachment" clause of RA 1405 against the absolute language of RA 6426.
