This is an impossible situation. If there is no option for enforcement, then remedy #4 cannot apply to Ruy Lopez. I am concerned about what I think is a serious oversight on the part of the Arbitration Committee.
This anomaly was actually pointed out earlier by Boraczek on talk pages, and Mav's airy response looked to me like a reluctance to admit the ArbCom (and he) had made yet another mistake in their rushing through of this unconsidered decision.
I say the ArbCom but mostly it was just Mav and Raul, as the others contributed little more than simply signing on. Such low participation makes it far more likely this sort of error will slip through. I hope the newly elected arbitrators regard themselves as having more of a role than being a warm body.
