Stаte O wаnts tо оpen а pilоt daycare program for preschool children and, to that end, it submitted the project for open bids as required by State O law. The lowest bid that met the criteria established by State O was submitted by a religious organization. The organization’s bid is low, in part, because the building in which the program would be housed is tax exempt under State O law under a religious institution exemption to property taxes. The organization agreed to operate under the conditions of the project contract, including the provision prohibiting the program from being used to espouse or promote any particular religious view. Studies have shown, however, that children in such situations tend to emulate their caregivers. State O decides to award the contract to the organization. A citizen of State O brings an action in a proper State O court seeking to set the award aside, claiming that it violates the United States Constitution. Is the citizen likely to prevail?
The Stаte оf Illiаnа sets up a private schооl tuition voucher program. Under the program, any elementary or middle school student who lives in what the statute defines as a “failing public school district” may receive $2,000 per year of tuition assistance toward any private school that accepts the student. The statute that sets up this program also includes other provisions supplying special aid, worth about the same $2,000 per student, for any student in a failing district who wishes to remain in public school but receive after-school tutoring at the public school. About 10% of eligible students choose to participate in the private school voucher program; of these, about 97% attend parochial school (mainly because non-parochial private schools in the state are so expensive that the $2,000 of assistance doesn’t defray enough of the tuition bill to make much of a difference). The voucher program is constitutional.
