But, in court docs obtained by TMZ Sports, the judge in the case rejected the arguments, explaining Westbrook's statements were just opinions, not defamation.
The judge explained, "whether a person is racist or whether a statement is racial is a matter of opinion which cannot be verified as true or false."
The judge added, "It is only in the free expression of these ideas that the nation can hope to heal the historic wounds of slavery and racial injustice that fester still today. That healing cannot occur if public dialogue about racism is silenced under threat of defamation liability."
The court also noted Westbrook’s in-game threats were "coarse and offense" ... but were not extreme and/or outrageous enough to recover damages.
The judge also said Keisel and Huff remained in the arena to watch the rest of the game and there was never any real risk that Westbrook would make good on his threats.
Long story short, Keisel (though he can still appeal the ruling) will get nothing from either the Jazz or Westbrook ... in yet another reminder to fans -- watch your mouth when you trash talk pros at a game.
