Sovereign citizen movement
The sovereign citizen movement (sometimes abbreviated as SovCits) is a loose group of anti-government activists, conspiracy theorists, vexatious litigants, tax protesters and financial scammers found mainly in English-speaking common law countries—the United States, Canada, Australia, the United Kingdom, and New Zealand. Sovereign citizens have a pseudolegal belief system based on misinterpretations of common law, and claim not to be subject to any government statutes unless they consent to them.
