Proposition 14, when voted into California law, became a part of the state constitution (Art. I, § 26). After state courts ruled that the amendment was against the law, advocates for the California Real Estate Association appealed to the United States Supreme Court. This document describes the ruling made by the US Supreme court that Art. I, § 26 of the California Constitution was invalid on the grounds that it violated the Equal Protection clause of the 14th Amendment to the US Constitution.
