Contact rule

[PABlue]

Contact rule (all divisions) Babe Ruth baseball (OBR rules)

"If a runner attempting to reach home plate intentionally and maliciously runs into a defensive player in the area of home plate, he will be called out on the play and ejected from the game. The objective of this is to penalize the offensive team for deliberate,unwarranted, unsportsmanlike action by the runner for the obvious purpose of crashing the defensive player, rather than trying to reach home plate. Obviously this an umpires judgement call."

This was copied directly from the 2006 rule book. The question I have is if this same kind of contact occurs at any of the other bases is the same rule in effect?
I know the rules for illegal contact and malicious contact for FED,LL and Legion.MY question is specific to this Division. We have a coach at the 12 and under age that thinks he's Billy Martin and loves to argue alot. He says that any other base but home his players can run into the fielder since it isn't specifically mentioned in the rule book.
This is only the second year for Babe Ruth ball in our area and I want to make sure that I'm calling this the right way.
