The legislative power shall be vested in a senate and assembly.

Article IV, §1 - ANNOT.

An act validating existing sewerage districts previously held to be unconstitutionally organized is within the power of the legislature. Madison Metropolitan Sewerage Dist. v. Stein, 47 Wis. 2d 349, 177 N.W.2d 131.

The power given vocational district boards to levy taxes does not violate this section. The manner of appointing board members is constitutional. West Milwaukee v. Area Bd. Vocational, T. & A. Ed. 51 Wis. 2d 356, 187 N.W.2d 387.

One legislature cannot dictate action by a future legislature or a future legislative committee. State ex rel. Warren v. Nusbaum, 59 Wis. 2d 391, 208 N.W.2d 780.

The legislature may constitutionally prescribe a criminal penalty for violation of an administrative rule. State v. Courtney, 74 Wis. 2d 705, 247 N.W.2d 714.

Provisions of s. 144.07 (1m) [now s. 281.34 (1m)], that void a DNR sewerage connection order if electors in the affected town area reject annexation to the city ordered to extend sewerage service, represents a valid legislative balancing and accommodation of 2 statewide concerns: urban development and pollution control. City of Beloit v. Kallas, 76 Wis. 2d 61, 250 N.W.2d 342.

Mediation - arbitration under s. 111.70 (4) (cm) is a constitutional delegation of legislative authority. Milwaukee County v. District Council 48, 109 Wis. 2d 14, 325 N.W.2d 350 (Ct. App. 1982).

The court will invalidate legislation only for constitutional violations. State ex rel. La Follette v. Stitt, 114 Wis. 2d 358, 338 N.W.2d 684 (1983).

Reference in a statute to a general federal law, as amended, necessarily references the current federal law where the act named in the statute is repealed and the law rewritten in another act. Because reference is stated as part of a contingency, it does not constitute unlawful delegation of legislative authority to U.S. Congress. Dane County Hospital & Home v. LIRC, 125 Wis. 2d 308, 371 N.W.2d 815 (Ct. App. 1985).

Proposed amendments to bills creating variable obscenity laws that would exempt motion picture films shown at theaters that comply with the film ratings of the motion picture association of America constitute an unconstitutional delegation of legislative power. 58 Atty. Gen. 36.

The one man-one vote principle is inapplicable to legislative committees since that principle applies only to the exercise of legislative powers and such powers cannot constitutionally be delegated to these committees. There has been no such unconstitutional delegation as to the joint committee on finance, the board on government operations, the joint legislative council or the committee to visit state properties. Legislative oversight of administrative rules discussed. 63 Atty. Gen. 173.
