Section 970.04 specifically limits the availability of a second preliminary examination in a criminal matter and precludes a request for a de novo hearing under the more general sub. (8). State v. Gillespie, 2005 WI App 35, 278 Wis. 2d 630, 693 N.W.2d 320, 04-1758. A party who requests a hearing de novo under sub. (8) is entitled to a hearing that includes testimony from the parties and their witnesses. Stuligross v. Stuligross, 2009 WI App 25, 316 Wis. 2d 344, 763 N.W.2d 241, 08-0311. The issuance of a search warrant is not an exercise of "[t]he judicial power," as that phrase is employed in article VII, section 2. Instead, issuance of a valid search warrant requires that the individual be authorized by law to issue the warrant, that he or she be neutral and detached, and that the warrant be issued only upon a showing of probable cause. Sub. (1) (b) does not impermissibly intrude upon "[t]he judicial power" granted to the courts by article VII, section 2 and is constitutional. State v. Williams, 2012 WI 59, 341 Wis. 2d 191, 814 NW 2d 460, 10-1551. The provision in sub. (8) for a circuit court to conduct a "hearing de novo" on review of a court commissioner's order presupposes that the court commissioner has conducted a hearing. A de novo hearing is a new hearing of a matter, conducted as if the original hearing had not taken place. Thus, a local rule precluding a new hearing upon stipulation or default does nothing more than expressly advise as to the practical consequences of consenting to a court commissioner's order.
