Unfortunately, there is no head on in the replay of that race to see where the infractions occurred and especially with left-handers like CWJ it's pretty hard to tell much from the side ons. To make matters worse it seems to take them weeks to get the stewards vision up which is presumably the video the stewards review prior to making those charges - e.g., still none from the 21/12 meeting at Ashburton which is a fat lot of good now, even though the note there says usually 3-4 days and I don't see why it should need to take that long with today's technology. From what I can see in this case it appears that CWJ only applied one back-hander with his hands off the reins a stride or two before the post, though he admitted the charge so presumably must have infringed.
