Halftime adjustments?

This is the case for all but a very few violations of rugby law.

Jeff already addressed that but I don't think that you really understood his explanation. Yes, when we see a foul/violation, we blow the play dead. The judgment lies in deciding first whether it actually was a foul or a violation. What might be a foul in a spectator's eyes is not necessarily a foul in the calling official's eyes. We generally use advantage/disadvantage on fouls only, but that statement isn't all-encompassing either.

If we decide that it is a foul or violation, we call it immediately. If we decide it isn't, we naturally don't call anything.

JR...I understood the earlier explanation. The difference is that when we see a clear violation (with some exceptions) we DON'T call it immediately...rather, we wait to see if the offended team can 'do something with it' and if they fail, THEN we blow the whistle. For example, in BB I sometimes see a player make a FG but because of a foul that occurs slightly before the shooting motion begins the whistle blows, the basket is negated, and the player is awarded FT attempts. In rugby, the whistle would be delayed and if the basket is made...play on...if the shot is missed...stop the play.
