The court may award to the prevailing party reasonable attorney's fees and costs, including a reasonable sum to cover the service of expert witnesses, if:
For purposes of this section, "bad faith" is that which is undertaken or continued solely to harass or maliciously injure another, or to delay or prolong the resolution of the litigation, or that which is without any reasonable basis in fact or law and not capable of support by a good faith argument for an extension, modification or reversal of existing law.
