Judicial Impartiality When Familial Ties Disqualify A Judge In Preliminary Investigations

When must a judge inhibit from a case? The Supreme Court clarifies that disqualification applies even at the preliminary investigation stage.


A judge related to a party within the sixth degree of consanguinity or affinity is disqualified from hearing a case—even during a preliminary investigation. This was the Supreme Court's ruling in Sales v. Calvan (A.M. No. MTJ-00-1331, February 27, 2002), which disciplined a municipal judge for conducting a preliminary investigation in a murder case involving his wife's uncle.

The case clarifies an important point for litigants and judges alike: the duty to inhibit is not limited to trial proceedings. It applies from the very start of a criminal case, including the preliminary investigation stage.

The Facts of the Case

Mayor Reynolan T. Sales of Pagudpud, Ilocos Norte was accused of murder following a shooting incident on August 2, 1999 that resulted in the death of former mayor Rafael Benemerito. The next day, a criminal complaint was filed against Sales before the Municipal Circuit Trial Court in Bangui, Ilocos Norte.

Judge Melvyn U. Calvan conducted the preliminary investigation on the same day the complaint was filed. He found probable cause for murder, issued a warrant for Sales's arrest without bail, and concluded the investigation without giving the accused an opportunity to submit a counter-affidavit. The records were then forwarded to the provincial prosecutor's office.

The Disqualification Issue

The complainant discovered that Judge Calvan's wife was the niece of the deceased. This made the judge related by affinity to the victim and to the complaining witness, the widow Thelma Benemerito, within the third civil degree.

Judge Calvan admitted the relationship but argued that the disqualification rule under Rule 137, Section 1 of the Rules of Court did not apply. He claimed that "to sit in a case" meant only to hear and decide a case, not to conduct a preliminary investigation, which he considered an executive function.

The Supreme Court's Ruling

The Supreme Court rejected this argument. Citing Re: Inhibition of Judge Eddie R. Rojas, the Court explained that "to sit" in a case means "to hold court; to do any act of a judicial nature." The prohibition is not limited to hearing evidence but includes resolving motions, issuing orders, and similar acts.

The Court held that the disqualification applies even at the preliminary investigation stage, where a judge must determine whether probable cause exists to charge an accused. The rationale, as explained in Garcia v. De la Peña, rests on the principle that no judge should preside in a case where he is not wholly free, disinterested, and impartial. The law conclusively presumes that a judge cannot objectively sit in such a case.

The disqualification is mandatory. The appropriate step for Judge Calvan would have been to immediately desist from the case, even at the preliminary investigation stage.

Failure to Follow Procedure

The Court also found that Judge Calvan failed to follow Rule 112, Section 3 of the Rules of Court. He appeared to rely on the old two-stage system of preliminary examination and preliminary investigation proper, which had been replaced by a single-stage proceeding. His failure to keep abreast of developments in law and jurisprudence amounted to gross ignorance of the law.

However, the Court found no evidence that Judge Calvan knowingly rendered an unjust order. The complainant failed to prove that the orders were patently contrary to law or made with deliberate intent to perpetrate an injustice.

Practical Takeaways

  • Disqualification starts early. A judge related to a party within the sixth degree of consanguinity or affinity must inhibit from a case even at the preliminary investigation stage.
  • The rule is mandatory. Written consent from all parties is required before a disqualified judge may proceed.
  • "Sitting in a case" is broad. It includes issuing orders, resolving motions, and conducting preliminary investigations—not just trial proper.
  • Judges must stay current. Reliance on outdated rules can result in administrative liability for gross ignorance of the law.
  • Remedies exist. A party who believes a judge is disqualified may raise the issue before the court or seek review of the proceedings through appropriate remedies.
