Any person who suffers any ascertainable loss of money or movable property, corporeal or incorporeal, as a result of the use or employment by another person of an unfair or deceptive method, act, or practice declared unlawful by R.S. 51:1405, may bring an action individually but not in a representative capacity to recover actual damages. If the court finds the unfair or deceptive method, act, or practice was knowingly used, after being put on notice by the attorney general, the court shall award three times the actual damages sustained. In the event that damages are awarded under this Section, the court shall award to the person bringing such action reasonable attorney fees and costs. Upon a finding by the court that an action under this Section was groundless and brought in bad faith or for purposes of harassment, the court may award to the defendant reasonable attorney fees and costs.
