When the case reached the Supreme Court, Chief Justice Morrison Waite supposedly prefaced the proceedings by saying, “The Court does not wish to hear argument on the question whether the provision in the Fourteenth Amendment to the Constitution which forbids a state to deny to any person within its jurisdiction the equal protection of the laws applies to these corporations. We are all of the opinion that it does.” In its published opinion, however, the court ducked the personhood issue, deciding the case on other grounds.

Then the court reporter, J.C. Bancroft Davis, stepped in. Although the title makes him sound like a mere clerk, the court reporter is an important official who digests dense rulings and summarizes key findings in published “headnotes.” (Davis had already had a long career in public service, and at one point was president of the board of directors for the Newburgh & New York Railroad Company.) In a letter, Davis asked Waite whether he could include the latter’s courtroom comment–which would ordinarily never see print–in the headnotes. Waite gave an ambivalent response that Davis took as a yes. Eureka, instant landmark ruling.

The Straight Dope: How can a corporation be legally considered a person?

And, uh, as much as I wish it was, this isn’t an April Fool’s joke.
