The practice of Jewish men covering their heads has been mentioned and considered in a number of cases in American courts. Some of the more common cases in which the wearing of religious headgear is at issue involve employment discrimination and incarcerated individuals. Rules governing military and athletic dress have also conflicted with the practice of wearing a yarmulke.
As we will see, the law applied in each situation depends on the nature of the case. Some examples of laws that are relevant to the wearing of religious headgear are: the First Amendment of the U.S. Constitution, Title VII of the Civil Rights Act of 1964 (prohibiting employment discrimination on the basis of religion and other characteristics), and the Religious Land Use and Institutionalized Persons Act.
