Abstract:

Although Louisiana and Illinois once passed laws to validate software shrinkwrap licenses, neither statute survived closer review. In the Vault v. Quaid decision, federal judges refused to enforce the Louisiana law insofar as license terms interfered with consumer rights under federal copyright law. The Illinois software shrinkwrap license enforcement statute was subsequently repealed due to industry dissatisfaction with it.
