the.com/adjudicator

The person paid to decide who's right when everyone insists they are.

means A person formally appointed to judge a dispute or competition and hand down a binding decision.

from From Latin adjudicare — 'ad' (to) plus 'judicare' (to judge, from judex, 'judge') — meaning literally 'to award judicially.' English pulled 'adjudicate' from this root around the 1600s for formal legal rulings, and 'adjudicator' followed as the agent noun — the one who does the awarding, whether in a courtroom, a dispute panel, or a talent contest.
