The NISL requires that each referee inspect ALL League Credentials prior to each game - this includes both player & coach passes, and game referee report from each team.
If the team(s) is missing ANY of the credentials listed, referees are instructed to obtain any missing information (i.e. Name, DOB, Club) and forward the information to the NISL office. The game will continue and be played under protest.
Any team found to have used an illegal player or coach, or forged any credentials, the game will automatically be declared a forfeit.
Football is a global sport and its rules must be interpreted and applied with absolute consistency wherever the game is played. FIFA therefore has a policy of ongoing training for its referees to ensure that refereeing standards continue to improve and the Laws of the Game are applied the same way everywhere.
