Shield laws protect the confidential relationship between reporters and their sources, on the theory that without such protection whistleblowers and other informants would not come forward, chilling the flow of information to the public. The privilege typically covers the identity of sources and may also extend to unpublished notes, drafts, photographs, and recordings.
Protections vary widely in scope. Some shield laws are absolute, barring any compelled disclosure; most are qualified, allowing courts to override the privilege when the information is critical to a case, unavailable from other sources, and outweighs the public interest in confidentiality. Eligibility rules also differ: statutes may define a "journalist" narrowly (employees of established news organizations) or broadly (anyone engaged in newsgathering, including bloggers and freelancers).
In the United States, there is no federal shield law. The Supreme Court's decision in Branzburg v. Hayes (1972) rejected a constitutional reporter's privilege under the First Amendment for grand jury proceedings, though Justice Powell's concurrence left room for case-by-case balancing. In response, the large majority of U.S. states have enacted statutory shield laws or recognized a privilege through court decisions. Federal proposals such as the PRESS Act have been introduced repeatedly but have not been enacted as of this writing.
Other jurisdictions take different approaches. In Europe, the European Court of Human Rights held in Goodwin v. United Kingdom (1996) that compelling a journalist to reveal a source violated Article 10 of the European Convention on Human Rights absent an overriding public interest. The EU's 2024 European Media Freedom Act also includes source-protection provisions.
For researchers, the practical questions are: Who qualifies as a journalist? What material is covered? What exceptions apply (national security, criminal defendants' rights, defamation suits)? And how does the law interact with subpoenas, search warrants, and surveillance powers such as those affecting metadata.
Example
In 2005, *New York Times* reporter Judith Miller was jailed for 85 days for refusing to identify a confidential source to a federal grand jury in the Valerie Plame leak investigation, a case that highlighted the absence of a U.S. federal shield law.
Frequently asked questions
No. As of this writing, there is no enacted federal shield law. Protection comes from state statutes, state court rulings, and a limited qualified privilege recognized in some federal circuits after Branzburg v. Hayes (1972).
