On January 25, 2019, the Illinois Supreme Court held in Rosenbach v. Six Flags Entertainment Corporation that plaintiffs are not required to allege actual harm in order to seek damages against private entities under the state’s Biometric Information Privacy Act (BIPA). BIPA regulates companies’ collection, retention, and disclosure of biometric identifiers. It further provides a private right of action for persons “aggrieved” by a violation of the Act for recovery of liquidated damages, injunctive relief, attorneys’ fees, and costs. By allowing suits for technical violations of BIPA’s notice and consent provision to go forward, the Rosenbach decision will likely encourage the filing of new cases under the Act and may influence the interpretation of data privacy laws in other states.
