ASA naming dispute
As part of the splinter of the American Speed Association caused by the 2004 season, the American Speed Association was broken up. The Late Model Series was reacquired by Varney, while other assets were sold to Racing Speed Associates, led by Dennis Huth.
On December, 2007, Dennis Huth filed a lawsuit against the ASA Late Model Series seeking to invalidate and cancel the ASA Late Model Series trademark registration. The ASA Late Model Series responded that the lawsuit is frivolous and without merit and plan counter sue Mr. Huth for damages caused by suit. 
On January 14, 2009, the naming dispute was settled. In the end, both parties were allowed to keep the "ASA" name, but the ASA Late Model Series was forced to come up with a new logo, and both parties agreed to inform the racing public that the ASA Late Model Series is not related to, affiliated with, nor sponsored or endorsed by American Speed Association or ASA Racing. 
On October 11, 2010 it was announced publicly that in an Order signed on October 7, 2010 by US District Court Judge Matthew Kennelly, has permanently barred Louis R. (Ron) Varney, Jr, ASA Late Model Series, LLC and all those acting in concert or participation with them, including specifically ASALMS, LLC from any further use of the ASA or ASA LATE MODEL SERIES brand on or in connection with automobile race events anywhere in the United States. The injunction was delivered at the 2010 Oktoberfest Race Weekend at the La Crosse Fairgrounds Speedway. This forced the ASA Late Model Series cars to remove the any decals with the "ASA" name, and the ASA Late Model Series trailer to be removed from the premises.
