Fed. R. Civ. Pro. 11

Rule 11 of the Federal Rules of Civil Procedure is a common method of the courts to curb frivolous litigation. Basically, any 'paper' (motion, pleading, complaint, etc.) filed before the court has to be certified by the attorney of record. This certification is a method to assure that the litigation is not being brought for an improper purpose. If the litigation is found to be brought for an improper purpose, the attorney of record can face disbarment, large punitive damages, or other penalties.
As I am sure most of you have seen, "diddy" has recently been sued by a woman, who claimed that he was responsible for 9/11, seeking $1,000,000,000 in damages. While it is purely speculation at this point, I would argue that this is a likely response by "diddy." After the woman filed the complaint, the first thing "diddy's" lawyer should do is file a Rule 11 motion, which, if granted, would immediately end the litigation, and possibly allow the court to take action against both the woman, and her attorney.
