The FIPJP international rules of petanque are made by the FIPJP International Umpires Commission. The FIPJP International Umpires Commission is a committee whose members are the FIPJP authorized international umpires (arbitres internationaux). The commission considers changes to the rules, and may propose a new version of the rules, every two years in even-numbered years — 2006, 2008, 2010, 2012, etc.
The normal practice is for the Commission to work on modifications to the rules for 12 months or more, and then to forward the revised version of the rules to the FIPJP Executive Committee for consideration at its spring meeting in April. In theory, the FIPJP Executive Committee then forwards the revised version to the national federations for comments and feedback.
Finally, the revised version is formally introduced and approved at the World Congress, which is held at the same time and place as the the World Championships (usually in September, October, or November). The FIPJP releases the rules in two languages — French (the official language) and English, and they are posted on the FIPJP’s web site.
Once the FIPJP rules are released, each national federation adopts the new international rules as their own national rules. For some nations (Spain, for instance) adopting the rules means translating the French-language version of the rules into the national language.
Often a national federation will modify the FIPJP rules before adopting them. Modifications can vary from terminology changes (to make the wording more idiomatic for a particular nation) to actual changes in rules. For example, in 2006, the FIPJP approved the use of synthetic (that is, non-wood) jacks, but the FPUSA later modified its national version of the rules to forbid synthetic jacks.
The World Championships mark the culmination of one year’s season of play and the beginning of another. Once the FIPJP approves and releases a revised version of the rules, the revised version comes into effect immediately and applies to the next season. However, because the World Congress is held toward the end of the year, and it takes some time for national federations to evaluate, modify, and adopt a revised version of the rules, most national versions of the rules are dated with the year after the year when the FIPJP version was approved.

It is not clear exactly when a new version of the rules goes into effect. Each rules document gives the date and location of the World Congress where the new version was accepted, but does not specify when the new version of the rules goes into effect.
Mike Pegg has said on his Ask The Umpire page that a new version goes into effect immediately after it has been accepted by the World Congress. But he has also said, in the introduction to the BPA’s English translation of the 2002 rules, that they go into effect on the first day of the following year.
The rule changes that were agreed at the World Congress of the Fédération Internationale de Pétanque et Jeu Provençal in Grenoble in 2002, and which come into effect on 1 January 2003, have been incorporated into this new translation of the Règlement Officiel de Pétanque.
