Answer:
The Act that was found unconstitutional by the Supreme Court because of the wording of the Fourteenth Amendment was the Civil Rights Act of 1875.
Step-by-step explanation:
The Civil Rights Act of 1875 was a federal law proposed by Republican Senator Charles Sumner and Republican representative Benjamin Butler in 1870 during the presidency of Ulysses S. Grant. The law was approved by the United States Congress in February 1875 and signed by President Grant on 1 March 1875. The legislative provisions guaranteed that everyone, regardless of race, skin color or previous condition of slavery was entitled to the same treatment in public places, for example transport and taverns.
In 1883, the Supreme Court declared it unconstitutional claiming that the congress had no power to regulate the conduct of individuals. The XIV amendment prohibits discrimination as long as it is a state that commits them, and not an individual; however many of the provisions of the law were reinserted in the Civil Rights Act of 1964 and in the Fair Housing Act using federal power to regulate inter-state trade.
