In Christian Assembly Rios De Agua Viva v. City of Burbank, (IL App., March 31, 2011), an Illinois appellate court refused to grant a congregation a preliminary injunction to permit it to operate a church on property it has contracted to purchase. The city recently amended its zoning ordinance precludes churches on the property in question. The church argued it had a vested right under the pre-amended ordinance to operate on the property. The court disagreed, since the church's argument was based merely on its belief that the pre-amendment ordinance violated state and federal law and the requirement that churches obtain a special use permit could be successfully challenged. The court went on to uphold the amended ordinance that excluded from commercial districts any uses that did not produce taxable income.
