honour compels me
There might have been a more subtle resolution, such as the one proposed by Tardet, but in the end how can you write and officially post rules for your tournament, then say: "woah, a situation for which this rule was made actually took place, who would have thought! Well then, let's just apply common sense and forget the rules, as they are clearly wacky!".
Dura lex sed lex, if the league is an organized event and not some improvised mess then we are bound to proceed with the rules which were set out for us and which every regiment accepted when applying. Change them afterwards, if that is universally requested, but let it all happen in orderly fashion. Otherwise, we can't even call this thing a league, since there can be a league with faulty rules, but a league exposed to have none? Methinks nope.
