When a judge has a personal stake in a case, they are supposed to step aside. The fairness of the whole system depends on no one being a judge in their own cause.
Recusal is when a judge or official removes themselves from a case because of a conflict of interest, or even the appearance of one. It comes from the Latin recusare, to refuse or decline. The judge declines to hear the matter.
The principle behind it is ancient: no one should be a judge in their own cause. A decision-maker with a personal interest in the outcome, financial, family, or political, cannot be trusted to be impartial, and even the suspicion of bias poisons confidence in the result.
It protects something fragile and essential: the legitimacy of the courts. People accept a judge's ruling only if they believe the judge was neutral. Recusal preserves that trust by keeping interested decision-makers off the case.
Yet the rules are debated, especially at the top. Lower-court judges follow detailed standards, but Supreme Court justices largely decide for themselves whether to step aside, a discretion that has drawn growing criticism and calls for clearer, binding ethics rules.
