TALLAHASSEE, Fla. (AP) - Opponents of gambling on barrel racing in Florida have won another preliminary legal victory as the number of cases filed over the issue continues to grow.
    
Administrative Law Judge Cathy Sellers on Friday said she would let the opponents amend their complaint.
    
That complaint alleges the state Division of Pari-Mutuel Wagering failed to adopt a rule on quarter horse barrel racing before permitting the new form of gaming at a facility in Gretna. Racing began Thursday in the Panhandle town.
    
The revised complaint adds two new parties. They are individuals who race quarter horses on traditional flat tracks.
    
It also adds new arguments for why the original petitioners have a right to challenge barrel racing.
    
They are the Florida Quarter Horse Racing and Florida Quarter Horse Breeders and Owners associations.
