Haw. R. Civ. P. 38

(a) Right preserved. The right of trial by jury as given by the Constitution or a statute of the State or the United States shall be preserved to the parties inviolate.

(b) Demand. Any party may demand a trial by jury of any issue triable of right by a jury by (1) serving upon the other parties a demand therefor in writing at any time after the commencement of the action and not later than 10 days after the service of the last pleading directed to such issue, and (2) filing the demand as required by Rule 5(d). Such demand may be indorsed upon a pleading of the party. Where by statute a jury trial is allowed on appeal to the circuit court from the prior determination of any court or administrative body, a trial by jury may be had if demanded in the notice of appeal, and if not demanded in the notice, the appellee may have a trial by jury by filing a demand within 10 days after the case is docketed in the circuit court.

(c) Same: Specification of issues. In its demand a party may specify the issues which it wishes so tried; otherwise the party shall be deemed to have demanded trial by jury for all the issues so triable. If the party has demanded trial by jury for only some of the issues, any other party within 10 days after service of the demand or such lesser time as the court may order, may serve a demand for trial by jury of any other or all of the issues of fact in the action.

(d) Waiver. The failure of a party to serve and file a demand as required by this rule and to file it as required by Rule 5(d) constitutes a waiver by the party of trial by jury. A demand for trial by jury made as herein provided may not be withdrawn without the consent of the parties.

(Amended May 15, 1972, effective July 1, 1972; further amended December 7, 1999, effective January 1, 2000.)
