How about instead of whinning and crying about the refs decision they just fight a rematch and get 3 judges to score it.
Unless there are going to be three judges in place for all English title fights then that's not really an option.
Non-title fights wouldn't normally have judges. although just looking at the BBBOC rules there would seem to be the option:
well if the stewerds don't deem having three judges appropriate for a rematch of a fight with such an outcome then when will it be appropriate?
