Declares that each person not otherwise disqualified, barred, or disabled by State or Federal law shall have the right to participate in a republican form of State government free from interference from unlawful violence and the reasonably perceived threat of such violence. Creates a private cause of action, as well as a government remedy (enforceable by the chief executive officer of any State) against any individual or organization for a violation of that right. Authorizes the court to award a reasonable attorney's fee to a prevailing plaintiff. Sets a five-year statute of limitations that begins with the date of discovery of the violation.

Authorizes an agency that determines that an agency employee or agent is being unlawfully and physically prevented from carrying out lawful duties by employees or agents of a State, county, or local government, to file a complaint with the Attorney General. Directs the Attorney General to investigate the complaint and, if the Attorney General finds the complaint is meritorious, to place in escrow any payments that otherwise would be made to that county under the Payments in Lieu of Taxes Act of 1976 until such time as such interference has ceased.
