(a) Appeal within 30 days after the arraignment to the superior court for a jury trial pursuant to the provisions of Rule of Criminal Procedure 21(a); or
(b) Proceed with a trial in the circuit court, which will constitute a waiver of the right to a jury trial and the right to appeal for a jury trial pursuant to RSA 502-A:12 and 599:1.
II. A circuit court shall not proceed with a trial under subparagraph I(b) unless it has conducted a colloquy with the defendant and finds that the defendant has knowingly, voluntarily, and intelligently waived his or her right to a jury trial.
