I'm looking at the question given: was the PU's refusal to accept the protest correct? My answer: hell no. Is this PU just afraid of a silly little protest? Get it right, bub. If you blew it, you blew it, but accept the protest of a rule interpretation and get that game moving.
As for the appeal, well, this is simply a missed base appeal. BR was supposed to tag the orange bag, but did not. They missed the bag. I've got another out.
