A California-based horse owner on Wednesday filed a lawsuit against the Kentucky Horse Racing Commission asking a Kentucky court to strike down a rule that restricts claimed horses to running at the track at which the horse was claimed until the track&rsquo;s meet is over.\r\nThe owner, Jerry Jamgotchian, filed the suit in Franklin Circuit Court, six weeks after officials at Churchill Downs and the state&rsquo;s racing commission cited the claiming rule in denying Jamgotchian the ability to enter a horse he claimed at Churchill in a race at Penn National. In the suit, Jamgotchian alleges that the rule is &ldquo;invalid under federal law as it violates the Commerce and Equal Protection Clauses&rdquo; of the U.S. Constitution.\r\nJamgotchian filed a lawsuit against the California Horse Racing Board in 2009 challenging a similar rule. In an out-of-court settlement, the CHRB agreed to drop the rule.\r\nRules restricting the ability of owners to enter claimed horses at out-of-state tracks are common in many states. The regulations are usually referred to as &ldquo;jail-time&rdquo; rules.\r\n&ldquo;We look forward to winning this case and making sure that all horse owners in the U.S., including the Commonwealth of Kentucky, have the opportunity to claim a horse and then race it anywhere in the world they want, without harassment, restriction or the threat of suspension,&rdquo; Jamgotchian said in a prepared statement.\r\nOn May 17, Jamgotchian claimed the horse Rochitta from a race at Churchill Downs. He later attempted to enter her in a June 4 race at Penn National, but was blocked by Kentucky racing officials.
