The use of external devices to alter the Pokémon in a player's party is expressly forbidden. Random checks will be performed throughout the tournament to determine whether or not an external device has been used to modify a player's party. Players found to have Pokémon that have been tampered with will be disqualified from the event, regardless of whether the player tampered with his or her game or received a Pokémon or item that was tampered with by someone other than the player. It is the player's responsibility to have legal Pokémon. Event officials have the final determination regarding the legality of a Pokémon.
A player should notify the staff immediately if he or she believes that there is a problem with an opponent's Pokémon. At the end of the round, all match results become final. Issues that go unreported until after the round has completed will not change the result of that match, regardless of whether there is a problem with an opponent's Pokémon.
Players and spectators are expected to demonstrate proper sportsmanship over the course of the event. A player may be disqualified from the event based on actions taken by friends or relatives who disrupt the operation of the tournament.
