(a) the action or proceeding was commenced, used or continued in bad faith, solely to delay or prolong the resolution of the litigation or to harass or maliciously injure another; or
(b) the action or proceeding was commenced or continued in bad faith without any reasonable basis and could not be supported by a good faith argument for an extension, modification or reversal of existing law. If the action or proceeding was promptly discontinued when the party or attorney learned or should have learned that the action or proceeding lacked such a reasonable basis, the court may find that the party or the attorney did not act in bad faith.
