Yerushalmi has been involved in filing several lawsuits against the city of Dearborn, Michigan, in response to treatment of Christian missionaries preaching to Muslims at the city's Arab Festival. Members of one group, Acts 17 Apologetics, had been arrested for disturbance of the peace; a jury acquitted them, and Yerushalmi's suit against the city resulted in the latter settling with a public apology and $300,000 in damages. A judge threw out a similar case Yerushalmi had filed the same year on behalf of a group called Bible Believers; Yerushalmi had sued after the group were asked to leave the festival after speaking for over an hour, due to concerns of public safety and order. The case is currently being appealed to the Sixth Circuit Court of Appeals.
