The time limit is one year right? So how about the holder of the briefcase, in the current case Ziggler, gets injured a month or so before MitB, after holding the case for 11 months. We are all lead to believe their contract will lapse before they are fit to return. Have the MitB PPV go ahead with the WHC MitB match being the first on the card. Then have the title match happen next and the new MitB holder successfully cash in after it. New WHC! Only for Ziggler to appear still with his injury and cash in. Double cash in on the same title. They've just have to get the timing right so it was less than one exact year. They could even have an enquiry on SD and admit that it was within minutes of the contract expiring.
