Stephen P. Halbrook is a Senior Fellow at the Independent Institute and an author and lawyer known for his litigation on behalf of the National Rifle Association.
 He has written extensively about the original meanings of the Second Amendment and the Fourteenth Amendment (the latter as applied to Second Amendment rights).
 He has argued and won three cases before the US Supreme Court: "Printz v. United States", "United States v. Thompson-Center Arms Company", and "Castillo v. United States".
 He has also written briefs in many other cases, including the Supreme Court cases "Small v. United States" (pertaining to the Gun Control Act of 1968) and "McDonald v. Chicago".
 In "District of Columbia v. Heller", he wrote a brief on behalf of the majority of both houses of Congress.
 More broadly, his decades of research on the Second Amendment contributed to the intellectual foundation of the "Heller" decision.
 He has written many books and articles on the topic of gun control, some of which have been cited in Supreme Court opinions ("Heller", "McDonald", "Printz v. United States").
 He has testified before congress on multiple occasions.
 Halbrook’s most important scholarly contribution, however, was the book "That Every Man Be Armed", originally published in 1986.

 It was the first major school prayer case decided by the Rehnquist Court.
 It ruled that schools may not sponsor clerics to conduct even non-denominational prayer.
 The Court followed a broad interpretation of the Establishment Clause that had been standard for decades at the nation's highest court, a reaffirmation of the principles of such landmark cases as "Engel v. Vitale", 370 U.S. 421 (1962) and "Abington v. Schempp", 374 U.S. 203 (1963) .
"Webster v. New Lenox School District", 917 F.2d 1004 (7th Cir.
 1990) was a court case in Illinois, in which a social studies teacher Ray Webster sued the New Lenox School District 122 in New Lenox, Illinois, which he accused of violating his First Amendment right to free speech for stopping him from teaching "creation science" in class.
 The court found however that the school district had a right to restrict Webster to teaching the specified curriculum, and that in any case the teaching of "creation science" was illegal, having been ruled to violate the establishment clause in the U.S. Supreme Court decision in "Edwards v. Aguillard", 482 U.S. 578 (1987).

Peloza claimed that Establishment clause of the United States Constitution along with his own right to free speech was violated by the requirement to teach the "religion" of "evolutionism".
 The court found against Peloza, finding that evolution was science not religion and that the Capistrano Unified School District school board were right to restrict his teaching of creationism in light of the 1987 Supreme Court decision "Edwards v. Aguillard".
 One of the three appeals judges, Poole, partially dissented from the majority's free speech and due process opinions.
 It was one in a long line court cases involving the teaching of creationism which have found against creationists.
 Peloza appealed to the Supreme Court, which declined to hear the case.
