The referee in boxing is the individual charged with enforcing the rules of that sport during a match.
However, that role has been progressively replaced by a panel of judges, except for domestic fights in some countries.
For professional matches a patch is usually worn on the left breast bearing the insignia of the organization sanctioning the fight.
The referee may also wear a patch on his left sleeve bearing the flag of his home country.
The main critique involves the subjective nature of boxing refereeing; there are guidelines for referees, but enforcement of the rules still involves judgement.
