Court documents show that the Office of the City Prosecutor of Quezon City charged Guban with perjury under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594.
The case, docketed as Criminal Case No. R-QZN-26-02698-CR, stems from an affidavit executed by Guban in September 2024, which was used during a House of Representatives quad committee hearing on illegal drugs, public order, and human rights.
According to the Information filed in court, prosecutors alleged that Guban “willfully, unlawfully and feloniously” made false statements under oath on material matters in his affidavit.
The document cited several portions of Guban’s statements, including claims involving alleged drug shipments and references to personalities such as businessman Michael Yang, lawyer Mans Carpio, and Rep. Duterte.
Significantly, the Information pointed out that Guban himself admitted that certain instructions and information he received came from Nilo “Small” Abellera Jr., and not from Rep. Paolo Duterte, despite earlier statements that mentioned the latter.
Prosecutors said these assertions were “purely based on hearsay and speculation,” adding that there was no evidence implicating Rep. Duterte in illegal drug trade or smuggling, contrary to Guban’s sworn statements.
The Information further noted that Guban acknowledged he did not disclose some of these allegations earlier due to alleged threats, raising questions on the credibility and consistency of his testimony.
The charge was approved and signed on March 9, 2026, following a preliminary investigation.
The court recommended bail for Guban’s provisional liberty at P48,000.
Rep. Duterte was listed among the witnesses in the case.
As of posting, Guban has yet to issue a public statement regarding the charges.
