EXPLANATION / SCOPE

The principle that justice must be seen to be done requires that the judge who decides the case must have heard the evidence. A judge who did not hear the evidence cannot competently decide the case. The practice violates fair hearing rights. The appearance of justice is as important as the reality. A party is entitled to have their case decided by the judge who observed the witnesses. The rule applies to both criminal and civil proceedings. The decision is a nullity. The principle reinforces the requirement that the decision-maker must be the one who assessed credibility. The remedy is a fresh hearing before a different judge.
