Defected Vehicle - what happens after 21 days?

[XCwillo]

So as a few of you would know, SICXC is kinda' grounded (still hoon it around base to fulfill my cravings of course) but since they required a blue slip to get the defect sticker of the XC, a lot of work had to be done to get it ready, and it's recently ticked over the 21 days they give you to fix it all. Went to the cop shop this arvo and the guy there couldn't tell me what happens after the 21 day period, so do any of you know?
Cheers
