Haw. Rev. Stat. § 634J-2: Motion for order requiring plaintiff to post security.

In any litigation pending in any court of this State, at any time until final judgment is entered, a defendant may move the court, upon notice and hearing, for an order requiring the plaintiff to furnish security. The motion must be based upon the ground, and supported by a showing, that the plaintiff is a vexatious litigant and that there is no reasonable probability that the plaintiff will prevail in the litigation against the moving defendant.
