In "Speiser v. Randall", the U.S. Supreme Court addressed the State of California's loyalty oath, as required by a California law enacted in 1954, as a condition of exemption from property tax. In applying for property tax exemption as a veteran of World War II, ACLU lawyer Lawrence Speiser had refused to sign the loyalty oath. The court ruled that because the state required the claimant to show they are not advocating state overthrow and hence are not criminals within the applicable laws, the loyalty oath requirement to obtain the tax exemption is unconstitutional. The burden of proof for a criminal action rests on the state and not on the individual private citizen.
