Delegation of Preliminary Investigation: A Judge's Duty and Its Limits

A judge cannot delegate preliminary investigation to court personnel. The Supreme Court explains why in Mago v. Judge Peñalosa-Fermo.


Delegation of Preliminary Investigation: A Judge's Duty and Its Limits

A judge who allows a stenographer to conduct a preliminary investigation commits gross ignorance of the law. This was the Supreme Court's ruling in Mago v. Judge Peñalosa-Fermo (A.M. No. MTJ-08-1715, March 19, 2009), a case that clarifies a fundamental rule in criminal procedure: the discretion to determine probable cause cannot be delegated.

The Case

Rodolfo Mago filed a complaint for grave coercion against a sheriff before the Municipal Trial Court (MTC) of Labo, Camarines Norte. The sheriff filed a counter-charge for grave threats against Mago and his sons.

During the preliminary investigation of the grave threats case, Judge Aurea G. Peñalosa-Fermo prepared a set of written questions based on the affidavits on file. She then handed these questions to her stenographer, who conducted the examination of Mago and his witnesses. The judge was not present during the examination.

Mago later filed an administrative complaint against the judge, alleging gross ignorance of the law and bias.

The Issue

The central question was whether a judge conducting a preliminary investigation may delegate the examination of witnesses to a stenographer or other court personnel.

The Ruling

The Supreme Court held that a judge cannot delegate this duty. Before the October 3, 2005 amendment to the Rules of Court, judges of municipal trial courts were empowered to conduct preliminary investigations. In exercising this power, they used their discretion to determine whether probable cause existed to bring a respondent to court.

The Court cited the basic principle that an officer entrusted with discretion cannot delegate it to another. The presumption is that the officer was chosen because he or she was deemed fit and competent to exercise that judgment. Unless the power to substitute another person is expressly given, the officer cannot delegate the duty.

The Court found that the judge's actions betrayed a lack of knowledge of procedure. By allowing her stenographer to conduct the examination—and worse, by allowing witnesses to read and write their own answers to prepared questions—the judge violated the rules on preliminary investigation. The Court noted that the rules required the investigating officer to personally examine the complainant and witnesses.

Why This Matters

The case underscores the importance of personal examination in preliminary investigations. The purpose of this examination is to allow the investigating officer to assess the credibility of witnesses and determine whether probable cause exists. This is a judicial function that requires the exercise of judgment and discretion.

When a judge delegates this function to a stenographer, the examination loses its judicial character. The stenographer merely records answers to prepared questions and cannot make the credibility determinations that the law requires.

The Penalty

The Court found the judge guilty of gross ignorance of the law or procedure, which is a serious charge under Section 8, Rule 140 of the Rules of Court. She was fined P20,000 and warned that a repetition of a similar infraction would be dealt with more severely.

Practical Takeaways

  • A judge conducting a preliminary investigation must personally examine the complainant and witnesses. This duty cannot be delegated to a stenographer, clerk, or any other court personnel.
  • The personal examination requirement exists to allow the investigating officer to assess credibility and determine probable cause—functions that require the exercise of judicial discretion.
  • Preparing written questions in advance and allowing a stenographer to propound them does not satisfy the requirement of personal examination.
  • Judges of first-level courts no longer conduct preliminary investigations after the October 3, 2005 amendment to the Rules of Court, but the principle against delegation remains relevant to all officers exercising investigative or quasi-judicial functions.
  • Administrative sanctions for gross ignorance of the law can include fines, suspension, or dismissal from service.
