McGowan v. Marylandgreen2 sentences2014While courts express various iterations of the rational basis test, we have often quoted the United States Supreme Court's articulation in McGowan v. Maryland, 366 U.S. 420, 425-26 (1961): [The Equal Protection Clause] permits the States a wide scope of discretion in enacting laws which affect some groups of citizens differently than others. 2014Having rejected the premise that Act 10 implicates a fundamental right, the plaintiffs' equal protection claim necessarily fails under rational basis review. ¶76 While courts express various iterations of the rational basis test, we have often quoted the United States Supreme Court's articulation in McGowan v. Maryland, 366 U.S. 420, 425-26 (1961): 20 Generally, when considering an equal protection challenge, this court will uphold the statute if we find that the legislative classification is supported by a rational basis. | 3 | 3 |

State v. Smithgreen2 sentences2025See Smith, 323 Wis. 2d 377, ¶12 . ¶48 Johnson also argues that it would be “fundamentally unfair for the government to allow the sale, purchase and use of [L]-meth without a prescription, but then punish that conduct if it is combined with driving, regardless of impairment.” However, this argument fails under the same rational basis analysis undertaken above. ¶49 In sum on this issue, Johnson has not proven beyond a reasonable doubt that prohibiting driving with any form of methamphetamine in the blood is 25 No. 2024AP79-CR arbitrary or irrational. 2018When the statute implicates a fundamental right or discriminates against a suspect class, this court applies strict scrutiny and the law will be upheld "only if narrowly tailored 'to serve a compelling state interest.' " Id. (quoting Milwaukee Cty. v. Mary F.-R. , 2013 WI 92 , ¶ 35, 351 Wis. 2d 273 , 839 N.W.2d 581 ). 6 In all other challenges, we review the law under the rational basis test and uphold it "unless it is 'patently arbitrary' and bears no rational relationship to a legitimate government interest."

Ferdon Ex Rel. Petrucelli v. Wisconsin Patients Compensation Fundgreen2 sentences2011From Ferdon , an equal protection case, MMAC cites the statement that judicial review under the rational basis standard requires a "thoughtful examination of not only the legislative purpose, but also the relationship between the legislation and the purpose." Ferdon, 284 Wis. 2d 573, ¶ 77 . 2006In analyzing whether a statutory classification meets the rational basis standard, we" 'are obligated to locate or, in the alternative, construct a rationale that might have influenced the legislative determination.'"

State, 64 Wis. 2d 6, 18-19 , 218 N.W.2d 734, 741-42 (1974) (footnotes omitted) : A legislative classification is presumed to be valid. | 2 | 4 |

Federal Communications Commission v. Beach Communications, Inc.green2 sentences2017The State also cites FCC v. Beach Communications, Inc., 508 U.S. 307, 315 (1993), in which the United States Supreme Court stated, "[LJegislative choice is not subject to courtroom fact-finding and may be based on rational speculation unsupported by evidence or empirical data." The State further notes the rational basis test "does not require the legislature to choose the best or wisest means to achieve its goals. 2014The rational basis test is deferential; the standard of review is "a paradigm of judicial restraint."
