Listen to Garth Brooks on iHeartRadio

The lawsuit against Garth Brooks by his former business partner will remain in Los Angeles Superior Court. says the country star's lawyer was trying to get the case moved to federal court, but the judge ruled against it.  One source is calling the decision "a loss for Garth," explaining that "his argument was shot down by the court."  Lisa Sanderson, who worked with Brooks for 20 years, launched her lawsuit in the spring. 

In her suit she calls the singer "paranoid," "angry," "deceitful" and "vindictive" in describing how he killed every great deal she brought to him to expand his acting interests. 

Sanderson says he has an out of control ego, citing Garth's refusal to take an offer to appear as a sniper in "Saving Private Ryan" because he wouldn't be the star of the movie. 

She also claims she lost out on salary, bonuses and profits over the years because of his false promises.  Sanderson is seeking $425,000 in damages.
