What the SOR governs

The SOR is the largest and most frequently used IJF instrument, turning what the Statutes set at the level of principle into operating rules: eligibility, nationality, entries and accreditation, weigh-in, competition systems, world ranking lists, judogi rules, refereeing rules, and the medical and anti-doping handbook. Unlike the Statutes, it is revised often — this version replaces one published less than a month earlier.

Athlete nationality and changing itsection 1.7

An athlete must hold the nationality of the federation entering them, evidenced by a valid passport; an athlete with several citizenships may compete for only one country.

  1. The three-year ruleAn athlete who has represented a country at the Olympic Games, world, continental or regional championships, or events on the IJF calendar may represent a new country only after three years have passed since last representing the former one.
  2. Shortening itThe IJF may shorten or waive the three years — but only on the written agreement of both national federations and with a passport for the new country. The authority is Rule 41 of the Olympic Charter and its Bye-law.
  3. The filing deadlineA request tied to a specific event must reach the IJF 21 days before that event's registration deadline; later than that, the IJF gives no assurance it will be processed in time.
  4. ExclusionsVeterans, military and kata competitors who appear on no world ranking list fall outside the rule and may change sporting nationality at any time on producing a passport.
  5. Refugee statusSeparate routes exist for athletes holding official refugee status and for the IJF Refugee Team, where a refugee travel document or photographic identity plus an IJF authorisation letter stands in for the passport.

Referee nationality runs a parallel regime of its own at section 1.8.

Power of amendment

The IJF states expressly that it may amend its rules "in a reasonable manner at any time" and notify members "by any method as the IJF deems appropriate" — email, website publication, or a declaration at a meeting. For anyone citing the SOR, that makes the version date part of the citation: a reference to "the SOR" without one points at a moving text.
