I think the reason for the severity of the rule is to prevent teams, top heavy with respect to skill level, from purposefully playing all their higher skill level players and then "oops" at the end. Given the points system, the high skill level teams could theoretically play 3 7's and win those matches 3-0 each scoring 9 points and making it impossible for the other team to win regardless of forfeits (which I believe are 2-0 each). That's 8 ball. Same argument though for 9 ball.
Whether you consider APA a recreational league or not, everyone still wants to win. One rule isn't any more important than another rule. Let's say one of the opponents that night inadvertently nudged the CB prior to shooting. Would you have said "Oh, no big deal, just go ahead and shoot."? I doubt it. The rule book is pretty small, it really isn't that difficult to know all the rules.
The OP made a mistake, now sack up and take it like a man. Learn from it and please don't blame the APA. I struggle to understand how the APA is at fault in the least in this situation.
