Sarkar v. Doe - PubPeer Subpoena Challenge
The ACLU filed a motion in Michigan state court challenging the constitutionality of a subpoena issued to the website PubPeer demanding that it turn over the identities of anonymous commenters. In March 2015, the trial judge ruled that PubPeer had to unmask one – but only one – of the commenters. Both PubPeer and the researcher appealed, and the ruling was upheld in December 2016.

Netchoice, LLC v. Bonta
This amicus brief highlights the constitutional defects of a California law that purports to protect consumer privacy but is actually an impermissible, content-based regulation of online speech.

The Warrant Clause in the Digital Age
The information generated by today’s digital devices and online services reveals private matters far beyond what one could learn from physical analogs. In a series of legal filings and a white paper, available below, the ACLU has argued that to keep apace with technological developments and adequately protect our privacy, the Fourth Amendment's warrant requirement must be interpreted robustly. Seizures and searches of digital data must be cabined to probable cause, limited to specific categories of information relevant to the investigation, and closely overseen by a neutral magistrate.
