arbitrator

This term describes a professional role centered on impartiality and authority. It carries a formal, legalistic connotation, typically appearing in corporate, labor, or international law contexts. The primary image is one of a balanced scale, where the individual possesses the power to impose a resolution that ends a deadlock.

While similar to a mediator, an arbitrator often has the power to make a final, binding decision, whereas a mediator merely facilitates a voluntary agreement. This distinction makes the word feel more decisive and authoritative than terms associated with simple negotiation.
