Related/Additional Activity

[gazebra]

This question rises from a correctable error situation. Foul 7 is called, but treated as Foul 6....throw-in by team A then results in Foul 8. Now the table says that it is actually 8 and 7 was not shot. Foul 8 is common. Is foul 8 considered "additional acitvity" that shall not be nullified under ART 5 (2-10). I can't find any def in any book at all, and the only thing close is the "additional activity" that occurs after the expiration of time (quarter/ OT possibility). I am trying to justify not shooting foul 8, but going back and shooting 7 under ART 6, since there has been no change in possession, with the lane filled, but not sure if that is possible. I know I have to enforce all flagrant, technical, or intentional fouls at this point, but common can be canceled at times. How would you handle?
