Having equal weight or importance; being perfectly balanced on both sides.
From Medieval Latin equiponderans, present participle of equiponderare (to have equal weight), combining equi- (equal) and ponderans (weighing). Used in philosophy and logic since the medieval period.
When a judge says both arguments are equiponderant, they're saying neither side wins because both sides weigh exactly the same—it's a perfect tie in the court of evidence!
