Graf, 72 Wis. 2d 179, 240 N.W.2d 387 (1976). The 10-day period for a jury demand did not begin at the initial appearance when the accused requested a continuance rather than entering plea under s. 345.34(1). City of Madison v. Donohoo, 118 Wis. 2d 646, 348 N.W.2d 170 (1984). The provision under this section for a 6, rather than 12, person jury for a speeding violation does not violate Art. I, s. 5, which provides that the right of trial by jury shall remain inviolate. Dane County v. McGrew, 2005 WI 130, 285 Wis. 2d 519, 699 N.W.2d 890, 03-1794.
