If Jay, Rusaku, or Warren want to take this up to the Council and have us officially talk about it and make a decision then just say the words. Other than that this fight is over by auto-forfeit.
Isn't that you making a decision, though?
Shouldn't this fall to Warren, as current Judge, to rule on?
Short answer: No, it is not the judge's job to enforce the biju rules, it's the Council's.
Long answer:
The judges in the match rule on whether the guidelines of zone fighting and general RP have been followed, while the Biju Council makes rulings on rule violations. This was a rule violation, one with a consequence outlined clearly in the Biju Rules.
Had Rusaku's post about the extension been followed up by nothing, then I would not have personally said anything until either called upon directly or until Rusaku had an issue with it. Imho, the violator should not be the only one who can miss out on not knowing the rules, as from my point of view the Council is not tasked with hunting for rule violations. It would make the job much more difficult and make us more like inquisitors than enforcers.
