Why have a service judge if they don't call faults on ridiculous serves? It's cheating, and if the officials ignore it, it may as well not be in the rules. There's absolutely no question on the ones posted by ant01, maybe the umpire should have stepped in, or the referee called, because the service judge from that game seems to be incompetent.
look at the height of the shuttle before it was hit ... if it is hit thats hands down a fault its like just below his armpits so ...
