The bill aims to reform the use of subpoenas for obtaining electronic communications records by adding protections to prevent abuse. It prohibits bulk collection of subscriber information and restricts the use of subpoenas to investigate constitutionally protected activities or retaliate against individuals. The bill also requires government entities to provide a certification attesting to a lawful purpose when using a subpoena and grants more freedom to service providers to disclose the receipt of a subpoena to customers unless a nondisclosure order is obtained. Additionally, it mandates public reporting of federal use of administrative subpoenas to increase transparency.
