Product overview

The California Anti-SLAPP Project (CASP) is a public interest law firm and policy organization that provides legal consulting services to help individuals and organizations defend against SLAPPs (Strategic Lawsuits Against Public Participation).

Expansion highlights5 records

Others

• Public Citizen Litigation Group: National public interest litigation group that engages in First Amendment and consumer-protection litigation. Comparable as a nonprofit public interest law firm model, but with broader subject-matter coverage and no anti-SLAPP specialization.
• Media Law Resource Center: Industry membership organization for media defense lawyers providing resources, amicus support, and policy advocacy on First Amendment and defamation issues. Adjacent peer via shared media-law community and overlapping expert network with CASP.

Direct peers

• Public Participation Project: Anti-SLAPP advocacy organization founded and led by CASP's founder Mark Goldowitz, campaigning for federal anti-SLAPP legislation and broader state-level protections. Directly comparable as the policy/legislative counterpart to CASP's litigation practice, with overlapping leadership and mission.

Broad incumbents

• Knight First Amendment Institute at Columbia University: Academic First Amendment litigation and advocacy organization. Overlaps with CASP on First Amendment defense work but operates nationally and at the federal/appellate level rather than as a California-focused consulting practice.
• Electronic Frontier Foundation: National digital civil liberties organization with substantial First Amendment and online speech litigation practice. Directly comparable on CyberSLAPP and anonymous-speaker defense (the §§1987.1/1987.2 niche CASP helped draft), but at far greater scale.
• Reporters Committee for Freedom of the Press: National organization providing pro bono legal support to journalists on First Amendment and SLAPP-related matters. Operates as a broader press-rights organization but engages in overlapping anti-SLAPP defense and amicus work.
• Center for Constitutional Rights: National public interest law firm engaged in constitutional and First Amendment litigation. Comparable as a mission-driven public interest litigator, though not California-specialized or anti-SLAPP-narrow like CASP.
• ACLU Foundation of Northern California: Regional ACLU affiliate that litigates First Amendment and free-speech cases in California courts. Overlaps with CASP on SLAPP-related constitutional litigation but operates across a much broader civil liberties portfolio.

Emerging players

• Citizen Media Law Project: Project providing legal resources for online speech and citizen journalism, including anti-SLAPP guidance. Compares as a niche, resource-driven player in the same CyberSLAPP and online-speech space CASP serves.

Regional players

• California First Amendment Coalition: California-focused First Amendment education and advocacy organization. Regional peer sharing CASP's California-specific scope and First Amendment mission, though it emphasizes transparency/open-government rather than anti-SLAPP litigation.
