1974) was an American legal decision in a case brought by evangelist William Willoughby against the National Science Foundation director H. Guyford Stever and the Board of Regents of the University of Colorado for using taxpayer money to fund textbooks developed by the Biological Sciences Curriculum Study (BSCS) because they included evolution instruction.
Willoughby claimed the pro-evolution curriculum was by extension also promoting secular humanism as the "official religion of the United States," and thus violated the Establishment clause of the US Constitution.
Willoughby accused scientists of "intellectual snobbery", and opposed tax revenues going to support education offensive to his religious views.
The Court also held that the Constitution's First Amendment prohibited states from demanding textbook teachings align with the religious beliefs of any particular group or individual.
