The Nevada Supreme Court has ruled that the state's minimum wage law does not violate federal law. The justices Thursday decided to uphold a voter-approved amendment to the state constitution that guarantees a base wage to Nevada workers. The court says federal regulations don't override the state constitution, and that the amendment does not promote arbitrary or discriminatory enforcement. The Las Vegas Review-Journal says the Western Cab Company had challenged the constitutionality of the law in a wage dispute with some if its drivers. The court found employers have enough notice about benefits they must provide to qualify to offer a lower wage in return for offering health insurance. The minimum wage is currently $7.25 if an employer provides health care, and $8.25 if not.
