Iniquum est aliquem rei sui esse judicem

The Latin phrase “iniquum est aliquem rei sui esse judicem” can be translated to English as “it is unfair for someone to be a judge in their own case” or “it is unjust for someone to be the judge of their own matter.” This phrase expresses the idea that a person who has a personal interest in a situation should not be allowed to make decisions or judgments about it. This would create a conflict of interest and bias and goes against the fundamental principles of fairness and justice in legal and ethical contexts.
