Cases shall not be continued upon stipulation of counsel alone, but continuance may
be granted by order of the court for good cause shown. A motion for continuance
shall be in writing, signed by the advocate or by the moving party if not
represented by counsel, and shall be filed with the court and served upon opposing
counsel. A motion filed less than five days before trial will not be considered or
granted unless it is established that unforeseenable or exigent circumstances
justify a continuance and that the moving party did not delay unreasonably in
seeking the continuance.
