Affinity and Judicial Disqualification: What the Supreme Court Clarified

The Supreme Court has clarified the limits of "affinity" as a ground for disqualifying a judge, ruling in Tiggangay v. Judge Wacas (A.M. OCA IPI No. 09-3243-RTJ, April 1, 2013) that a judge is not related by affinity to the blood relatives of his or her own blood relative's spouse. The case also underscores that a litigant who never moved for inhibition during trial cannot use a judge's adverse ruling as a reason to file a belated administrative complaint.

The Facts of the Case

Complainant Johnwell Tiggangay lost the mayoralty race in Tanudan, Kalinga to Rhustom Dagadag by 158 votes in the May 2007 elections. Tiggangay filed an electoral protest, which was raffled to the sala of Judge Marcelino Wacas of the Regional Trial Court, Branch 25, Tabuk City. In August 2008, Judge Wacas ruled that Dagadag won, but reduced the margin to 97 votes. Tiggangay's appeal to the COMELEC was later dismissed.

Only after the adverse ruling did Tiggangay file an administrative complaint against Judge Wacas, alleging impropriety and partiality. He claimed that Judge Wacas was Dagadag's second cousin by affinity because Judge Wacas's aunt was married to Dagadag's uncle. He also alleged that Judge Wacas and his wife attended Dagadag's victory party.

The Issue

The central question was whether Judge Wacas should have inhibited himself from hearing the case due to his alleged relationship by affinity with Dagadag, and whether his attendance at the victory party constituted impropriety.

What "Affinity" Actually Means

The Supreme Court took the opportunity to define the concept of affinity precisely. Affinity is the relationship that one spouse has to the blood relatives of the other spouse—the relationship by marriage commonly referred to as "in-laws." The Court cited the classic rule: a husband is related by affinity to his wife's brother, but not to the wife of his wife's brother. This is called affinitas affinitatis—affinity of affinity—which is not recognized.

Applying this to the case: Judge Wacas is related to his aunt by consanguinity. Through his aunt's marriage to Dagadag's uncle, Judge Wacas became the nephew-in-law of Dagadag's uncle. But Judge Wacas is not related by affinity to the blood relatives of that uncle—which includes Dagadag. The relationship between Judge Wacas and Dagadag was simply too remote and did not fall under the mandatory disqualification in Section 1, Rule 137 of the Revised Rules of Court, which covers relationships within the sixth degree of consanguinity or affinity.

Burden of Proof and Belated Complaints

The Court also emphasized that in administrative proceedings, the complainant bears the burden of proving the allegations with substantial evidence. Mere allegations are not evidence. Tiggangay failed to present substantial proof of the alleged relationship or the victory party attendance.

More importantly, the Court noted that Tiggangay never moved for Judge Wacas's inhibition during the entire proceedings. The Court viewed the complaint as a belated attempt to "get back" at the judge for an adverse ruling, citing the principle that "a litigant cannot be permitted to speculate upon the action of the court and to raise objections only after an unfavorable decision has already been rendered."

The complaint was dismissed for lack of merit.

Practical Takeaways

• Affinity is limited. A judge is disqualified by affinity only if the judge (or the judge's spouse) is related to a party within the sixth degree by marriage. The blood relatives of a judge's in-law's blood relatives are not covered.
• Raise inhibition early. If a party believes a judge is disqualified, the proper remedy is to file a motion to inhibit during the proceedings—not to wait for an unfavorable ruling and then complain.
• Substantial evidence is required. In administrative cases against judges, the complainant must present credible, relevant evidence. Uncorroborated testimony from interested witnesses will not suffice.
• Judges may still voluntarily inhibit. Even when mandatory disqualification does not apply, a judge may, in sound discretion, inhibit for just and valid reasons—but the failure to do so is not automatically misconduct.
