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.
- 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.
- 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.
- 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.
- 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.
- 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.
