51. Supremacy
 
    a. "The plenary authority of a legislature operates to restrict and limit the exercise of all municipal powers, whether public or governmental, proprietary or private."
Lamb v. Mirin, 90 Nev. 329, 333, 526 P.2d 80 (1974). No. 17.
 
    b. "We are constrained to note that even if Henderson had expressly annulled all master plans approved prior to the effective date of the new code, we would have substantial doubts concerning the validity of such an attempted circumvention of the policy dictates of NRS 278.250(2) as elucidated by this court in Nova Horizon. As we there observed, Nevada's statutory scheme mandates that municipalities adopt zoning regulations that are in substantial agreement with approved master plans. Nova Horizon, 105 Nev. at 96, 769 P.2d at 723. Assuming, therefore, that submission of a new master plan was intended as part of the zoning process under the new code, as the district court concluded, Henderson would still have been required to extend deference to the 1989 master plan in the process of approving the new plan. The guarantees afforded Nevada's developers by the Legislature may not be circumvented by municipal ordinance."
American West Dev. v. City of Henderson, 111 Nev. 804, 809, n. 3., 898 P.2d 110 (1995). No. 46.
 
    c. "There is no state law indicating that the ruling of the State Engineer preempts a county or other governmental entity from enacting zoning laws that impose limitations on water use that are more restrictive than those of the State Engineer. .... County and local governments can place more burdensome restrictions on local growth and development as long as those restrictions are consistent with the relevant long-term comprehensive plans, Nevada law, and notions of public welfare."
Serpa v. County of Washoe, 111 Nev. 1081, 1085, 901 P.2d 690 (1995). No. 47.
