Nebraska LB 642 establishes the Artificial Intelligence Consumer Protection Act, imposing obligations on developers and deployers of high-risk AI systems — defined as systems that make consequential decisions (employment, housing, lending, healthcare, insurance, education, legal services, government services, and criminal justice) without human review. Developers must provide deployers with documentation on intended uses, training data, known limitations, discrimination risks, and mitigation measures, and must maintain a public use case inventory. Deployers must implement risk management programs, complete impact assessments, notify consumers before AI-driven consequential decisions, explain adverse decisions, and offer data correction and appeal opportunities. The Attorney General has exclusive enforcement authority with a mandatory 90-day cure period before initiating action; no private right of action exists. Extensive carve-outs apply for insurers, financial institutions under prudential regulation, federal contractors, federally approved systems, and healthcare providers with human-in-the-loop.
