Either the rules too complicated/ambiguous, in which case the AFL again show that they are a bunch of numties, or no one from the AFL, Hawks and Suns saw the error until it was too late, which seems highly suspicious (easier to seek forgiveness than approval). Either way, if the trade was put in with insufficient time to find this error, then it should be made null and void. If not, we now have a precedent where we can wait until 1.59.59 (EDST) to submit a dodgy trade, after which we say sorry and move on with our trade ratified.
