Rules should be interpreted by the players directly involved in the play, or by players who had the best perspective on the play (3.A). Players may seek the perspective of sideline players to clarify the rules, and to assist in making the appropriate call.

Spirit of the Game: Ultimate relies upon a spirit of sportsmanship that places the responsibility for fair play on the player. Highly competitive play is encouraged, but never at the expense of mutual respect among competitors, adherence to the agreed upon rules, or the basic joy of play. Protection of these vital elements serves to eliminate unsportsmanlike conduct from the Ultimate field. Such actions as taunting opposing players, dangerous aggression, belligerent intimidation, intentional infractions, or other win-at-all-costs behavior are contrary to the spirit of the game and must be avoided by all players.
