G.R. No. L-38383 - Fortun vs. Labang

Judge Willelmo C. Fortun, then incumbent Judge of the Court of First Instance of Zamboanga del Sur and Pagadian City, Branch III, filed a prohibition and certiorari proceeding.
The petition arose from allegations made against him concerning an irregularity in his claim for gasoline allowance, initiated by a letter-complaint from a member of the bar and supported by an affidavit from a former employee.
The complaint was later endorsed by five of the nine members of the Board of Directors of the local chapter of the Integrated Bar of the Philippines (IBP), who had previously experienced unfavorable outcomes in cases before Judge Fortun.

On February 16, 1974, respondent City Fiscal Rufino O. Labang, acting with what was described as "precipitate haste," issued a subpoena (I.S. Nos. 392-403-74) against Judge Fortun without strictly following mandatory procedural requirements under Presidential Decree No. 77, Executive Order No. 264, and Rule 140 of the Revised Rules of Court.
On the morning of February 18, 1974, Judge Fortun was served the subpoena in a crowded courtroom, an act which was perceived as public and humiliating, undermining the confidentiality typically required in proceedings against judges.
Prior to the issuance of the subpoena, the complaint had already triggered administrative charges, initiated by the letter-complaint of Attorney Martin Vera Cruz and later ratified by a divided and seemingly vindictive local IBP board resolution.

Judge Fortun argued that the issuance of the subpoena violated the due process requirements and was motivated by vindictiveness, given the personal history of conflicts with certain IBP members who had repeatedly lost their cases before his court.
In his reply, Judge Fortun contended that the actions against him—initiated without affording him an opportunity to be heard—demonstrated an oppressive exercise of legal authority.
The petition included strong supporting evidence, such as a detailed account of the IBP board’s composition and the inherent bias arising from the members’ previous encounters in his courtroom.
To bolster his claim, Judge Fortun quoted, in full, a statement from retired Justice J. B. L. Reyes, then President of the Integrated Bar of the Philippines, which criticized the chapter’s failure to observe due process and fairness.

A temporary restraining order was issued on March 25, 1974, thereby halting the enforcement of the subpoena and the subsequent investigation.
While the respondent City Fiscal provided a comment on May 6, 1974, alleging substantial compliance with procedural norms, the private respondents (the IBP members) did not significantly contest the petition’s assertions.
Judge Fortun later filed a reply on June 27, 1974, emphasizing that the complaint and corresponding administrative actions were caricatures of due process violations intended to humiliate and discredit him.

The case was framed within the context of the court's equitable powers to restrain the misuse of legal authority, notably by invoking the doctrine established in Dimayuga and subsequent cases.
It raised significant concerns about the potential abuse of prosecutorial and administrative processes to serve personal or vindictive ends, which could adversely affect public confidence in the judicial system.

Whether the remedy of prohibition is available to forestall the enforcement of a subpoena issued in violation of due process and procedural requirements.
Whether such a remedy can be justifiably invoked to prevent the use of judicial processes as a tool for vindictiveness against a judge.

Whether the failure to comply with the mandatory procedural provisions under Presidential Decree No. 77, Executive Order No. 264, and Rule 140 of the Revised Rules of Court constitutes a breach of due process.
Whether the public and hasty service of the subpoena, particularly in a manner that humiliated the petitioner, amount to an oppressive exercise of legal authority.

Whether the actions of the Integrated Bar of the Philippines Chapter, including the divided vote and absence of procedural fairness in initiating administrative and criminal charges, demonstrate mala fide intent.
Whether the lack of opportunity afforded to Judge Fortun to present his side violates the fundamental tenets of natural justice and the rule of law.
