Foul on scoring play

[ljudge]

Last year a new rule was put in that would allow a 1/2 the distance penalty on a try if there was a foul by the opponent of the scoring team on a play.

eg: A's ball 1st and 10 at B's 5. If team B commits a live-ball personal foul on the play it will be enforced on the try instead of automatically declining. That I know for sure and was new in 2004.

If A illegally shifts and B returns an interception for a TD I thought that foul was still declined even under the new rule. I thought someone told me the only way we would enforce a foul against team A when B intercepts and scores is if team A fouls AFTER team B gains possession. I'm having a brain lapse on this one. I looked it up in the rule book and I can't seem to find it so I'm guessing I was incorrect. Anyone know?
