Laws of Rugby

The laws of rugby are extensive. To quote the IRB charter:

"It is through discipline, control and mutual respect that the spirit of the game flourishes and, in the context of a game as physically challenging as rugby, these are the qualities which forge the fellowship and sense of fair play so essential to the game’s ongoing success and survival. Old fashioned traditions and virtues they may be, but they have stood the test of time and, at all levels at which the game is played, they remain as important to rugby’s future as they have been throughout its long and distinguished past. The principles of rugby are the fundamental elements upon which the game is based and they enable participants to immediately identify the game’s character and what makes it distinctive as a sport".
