Of the 150 cases involving the Fourteenth Amendment heard by the Supreme Court up to the Plessy v. Ferguson case in 1896 that established the legal standing of "separate by equal," 15 involved blacks and 135 involved business entities. The scope of the Fourteenth Amendment to secure the political rights of former slaves was so restricted by the Supreme Court that blacks won only one case. The expansive view of the Fourteenth Amendment that comes down to Constitutional Law classes today is the result of corporations using the Fourteenth Amendment as a shield against regulation. Ultimately, the Plessy decision left Jim Crow laws, state laws discriminating against blacks, in place because of doctrines developed in those corporate shield cases.
