Affinity and Judicial Disqualification: What the Supreme Court Clarified

The Supreme Court recently had the opportunity to clarify a frequently misunderstood point in judicial ethics: when a family relationship by affinity requires a judge to inhibit from a case. In Tiggangay v. Judge Wacas, the Court explained the precise meaning of "affinity" under the Rules of Court and reminded litigants that allegations of bias must be supported by substantial evidence. The ruling is a useful guide for lawyers and litigants alike on the boundaries of judicial disqualification.

The Facts of the Case

Complainant Johnwell Tiggangay lost a mayoralty race in Tanudan, Kalinga to Rhustom Dagadag by a slim margin of 158 votes. Tiggangay filed an electoral protest, which was raffled to the sala of Judge Marcelino Wacas of the Regional Trial Court, Branch 25, Tabuk City. Judge Wacas ruled in favor of Dagadag, though reducing the winning margin to 97 votes.

After the decision, Tiggangay filed an administrative complaint against Judge Wacas for impropriety and partiality. He alleged that the judge was Dagadag's second cousin by affinity — specifically, that Judge Wacas's aunt was married to Dagadag's uncle. Tiggangay also claimed that Judge Wacas and his wife attended Dagadag's victory party after the decision was rendered.

The Issue

The central question was whether Judge Wacas should have inhibited himself from hearing the case given his alleged relationship by affinity with one of the parties. A related issue was whether the judge's alleged attendance at the victory party constituted impropriety.

The Ruling: No Disqualification by Affinity

The Supreme Court dismissed the complaint for lack of merit. The Court held that even assuming the aunt of Judge Wacas was indeed married to the uncle of Dagadag, this did not create a relationship by affinity between the judge and the party-litigant.

The Court explained that affinity is the relationship that one spouse has to the blood relatives of the other spouse. It is a relationship by marriage — what people commonly call "in-laws." The doctrine rests on the principle that marriage makes husband and wife one: the husband has the same relationship by affinity to his wife's blood relatives as she has by consanguinity, and vice versa.

Critically, the Court clarified that there is no affinity between the blood relatives of one spouse and the blood relatives of the other. This situation — where the relative of one spouse marries the relative of the other spouse — is called affinitas affinitatis, which does not create a disqualifying relationship.

Applying this to the case: Judge Wacas was related to his aunt by consanguinity. By virtue of his aunt's marriage to Dagadag's uncle, Judge Wacas became the nephew-in-law of that uncle. But Judge Wacas was not related by affinity to the blood relatives of that uncle — which would include Dagadag. Likewise, Dagadag was the nephew-in-law of Judge Wacas's aunt, but not related by affinity to Judge Wacas. In short, the judge and the party were not in-laws of each other.

The Burden of Proof in Administrative Cases

The Court also emphasized that administrative cases require only substantial evidence — that amount of relevant evidence a reasonable mind might accept as adequate to support a conclusion. The burden rests on the complainant. Mere allegations are not evidence.

Here, Tiggangay failed to present substantial evidence of the alleged relationship. His driver's testimony about the victory party was found incredulous: the driver claimed to have observed the party for four hours but could not name a single attendee, even though the attendees supposedly came from his own place. This testimony was contradicted by another witness who testified there was no party at Dagadag's ranch on the date in question.

The Importance of Timely Objection

The Court also noted that Tiggangay never moved for Judge Wacas's inhibition during the entire proceedings. The complaint was filed only after an adverse decision and after the COMELEC dismissed his appeal. The Court viewed this as a belated attempt to attack the judge for an unfavorable ruling, observing 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."

Practical Takeaways

• Affinity is narrower than many assume. A judge is disqualified only when related to a party within the sixth degree of consanguinity or affinity. The "in-law" relationship does not extend to the blood relatives of the other spouse's relatives.
• File a motion to inhibit early. A party who believes a judge is disqualified should raise the issue promptly. Waiting for an unfavorable decision before complaining can weaken the claim.
• Allegations need evidence. In administrative cases against judges, the complainant bears the burden of proving the charge with substantial evidence. Uncorroborated affidavits from interested witnesses may not suffice.
• Judges enjoy the presumption of regularity. Absent clear and convincing proof of bias or partiality, the Court will not assume a judge acted improperly.
