At first glance, it may seem strange that among the rules of football there is only the fifth mention of referees. However, it is not so surprising when you consider that in the early days of football there was not the slightest mention of referees in the Laws of the Game.
The reason was simple: there were no referees! Any dispute was settled by a discussion between the two captains, and in most decisions it was assumed that the players were so honest and fair that there was no disagreement that could not be resolved in this sporting way. As football became more popular and competitive in the late 19th century, the need for an independent referee was essential.
The increased role of the referee therefore required a clear definition of his powers. These are found in Rule 5, while Rule 6 focuses on assistant referees. Rule 5 is divided into 18 parts, each of which defines either a duty that the referee must perform or a power that he may exercise when required in the game.
Enforcement of the Laws of the Game The referee has a duty to enforce the Laws of the Game. Quite simply, that is the main reason he or she is there. The referee is expected to observe and interpret the Laws of the Game to ensure a fair, reasonable and competitive game of football.
He or she shall officiate the game in cooperation with the assistant referees AND the fourth official, if applicable.
The role of the assistant referees and the fourth official is discussed in more detail below. Obviously, a good mutual understanding between the referee and his two assistants is essential for the game to be officiated effectively and competently. Fourth officials only exist in the Bundesliga, the first and second divisions and, in exceptional cases, in some other competitions or matches.
