The amendment was so restrictive that the Michigan Supreme Court had to determine not only whether it prohibited direct aid, but also whether or not it prohibited the wide variety of indirect services that were shared, supported, or financed by private agencies and the state and federal government. In the Traverse City School District case, the court interpreted the amendment to outlaw direct aid, but to continue to allow indirect and auxiliary services to be performed with taxpayer funding. However, the Court also ruled that a portion of the amendment which prohibits the use of public money to support the attendance of any student or the employment of any person at any such nonpublic school or at any location or institution where instruction is offered "in whole or in part" to nonpublic students was unconstitutional, void, and unenforceable because it contravened free exercise of religion.62 The free exercise of religion is an important guarantee provided by the United States Constitution, and the Court ruled that Michigan voters could not overrule the U. S. Constitution.
