Which court case tested the constitutionality of the Civil Rights Act of 1866?

The case that tested the constitutionality of the Civil Rights Act of 1866 is Jones v. Mayer. This landmark Supreme Court decision in 1968 reaffirmed the federal government's power to enforce the Act, which was designed to eliminate racial discrimination in property transactions. The ruling held that Section 1982 of the Civil Rights Act of 1866, which guarantees all citizens the right to buy, sell, or lease property regardless of race, was constitutional and that racial discrimination in housing was a violation of the Act.

The significance of Jones v. Mayer lies in its affirmation that private individuals could not discriminate based on race in real estate transactions and that Congress had the authority to eliminate such discrimination under the Thirteenth Amendment, which abolished slavery. This case played a crucial role in shaping civil rights laws in the United States, highlighting the federal commitment to combat racial discrimination and uphold equality in housing.

Other options do not align with the question regarding the specific court case associated with testing the constitutionality of the Civil Rights Act of 1866. For example, while the 13th Amendment deals with the abolition of slavery, it does not directly address the Civil Rights Act of 1866 as a court case does.
