The Halt Abusive Internet Lawsuits Act of 2026 would prevent lawsuits against businesses for collecting, processing, or sharing user information and communications when done for commercial purposes. This protection would apply to federal and state laws governing wiretapping, eavesdropping, and electronic surveillance, including California's strict Invasion of Privacy Act. The bill broadly defines commercial purposes to include business operations, marketing, responding to customer input, and facilitating sales, as well as any other commercial activity defined by state law. Any existing lawsuits filed under these privacy laws would be immediately dismissed and could not proceed after the bill's enactment. The legislation effectively shields digital commerce companies from privacy-based litigation related to common data collection practices like cookies, pixels, and analytics tools.
