Bulldozing - allowed?

[sanddrag]

I had a discussion with the head ref at LA. It went something like this:

The head ref told me that "bulldozing" is illegal because of a rule against "herding" but, the rules talk about "posession" in which case you are not allowed to possess more than one ring and posession is defined as the ring touching the robot at MORE than one point (Q/A forums). I asked the head ref, "if we have a ring, and use it to push another ring, where the second ring would not be touching the robot, is this considered penalty deserving multiple posesstion?"
and I got a "yes. This will be a penalty, you should not do this" Then I said "all we want to do is plow throught the rings up against the wall. Will we get a penalty?" and I got a "yes, you are moving multiple rings with intent"

Is that correct? I mean, clearly there is a difference of opinion here. I need to know how it's being called other places and what rules apply.

Thanks.
