The purpose of the rules of Ultimate is to provide a guideline describing the way the game is played. It assumed that no Ultimate player will intentionally violate the rules; thus there are no harsh penalties for inadvertent infractions, but rather a method for resuming play in a manner that simulates what would most likely have occurred had there been no infraction.

In Ultimate, an intentional foul is considered cheating and a gross offense against the spirit of sportsmanship. Often a player is in a position where it is clearly to a player's advantage to foul or commit some infraction, but that player is morally bound to abide by the rules. The integrity of Ultimate depends on each player's responsibility to uphold the spirit of the game, and this responsibility should not be taken lightly.
