This came up during the Grand Pacific Open. A player requested a last round bye and/or withdrew, I can't remember the exact request. That person, even with a zero point bye in the last round, still won a prize. To my surprise I discovered that there is a CFC rule that anyone who does not complete the last round forfeits any prize. Furthermore, the CFC rule goes on to say that a "valid reason" for withdrawing over-rides the rule. The valid reason, in our case was "I need to report to work".
The rule seems odd to me and unenforceable since there is no way of validating a "valid reason".
