RobertJasiek: Splitting only two entries already into Famous and Less Famous is a good joke. You would not believe how eagerly the so called "less famous" dispute has been discussed since its occurrence. According to my observation, much more than the "famous" disputes. Of course, this is only my subjective view as an involved person. Anyway, degree of fame is rather irrelevant here. I suggested "Famous Rules Disputes" as a headline so that other Wiki users would be motivated to list more well known (or, if you want, "famous") disputes.
