Each country should provide minimum number of referees according to the following table :

 No of
Athletes per
      Min. Number of Referees
 1 – 6  1  1  1  0  0
 7-12  2  2  2  1  1
 12+  3  2  2  1  1

A fee of 800 USD (680 euro) will be requested for not having the right number of referees and collected by the JJIF on the spot (conditioned for participation before the draw). This rule doesn’t apply to new members during the first 3 years.
Referees should attend the briefing meeting and be available.

Neither the organizing committee nor the JJIF will be responsible for not respecting this obligation. However, if there won’t be enough referees for the competition to take place in good conditions, the JJIF Technical Commission may decide to complement the pool of referees with Continental referees.
