The American Civil Liberties Union of Hawaii is suing the state, arguing its Preschool Open Doors program, which provides preschool tuition subsidies for low-income families, violates the state and U.S. constitutions by providing public funds for religious observations and teachings. The lawsuit was filed Monday in Circuit Court and names Patricia McManaman in her official capacity as director of the state Department of Human Services, which runs the Open Doors program. The lawsuit is asking the court for an injunction prohibiting the state from paying religious providers to expend public funds on religious instruction. The state says monthly preschool tuition subsidies are provided directly to qualified families for up to one year. The families decide which of the approximately 1,000 child care programs licensed by the state, including about 650 preschools, to send their child.
