One of the complaints, the one giving rise to the Rule 11 sanction at issue in this case, alleged a nationwide conspiracy to fix prices and to eliminate competition through an exclusive retail agent policy and uniform pricing scheme, as well as other unfair competition practices such as resale price maintenance and territorial restrictions.
