A local Islamic association filed an application for a zoning variance to build a mosque. A bunch of local residents objected to it because they didn't want a mosque in the neighborhood. The application for the variance was rejected.
The Islamic association filed a Federal lawsuit on religious liberty grounds, and they won the case. I predicted this last year when the story first hit the news -- because the exact same decision was made in a similar case involving a yeshiva and dormitory in New Jersey last year.
If the residents who objected to the mosque had simply objected to it on grounds that had nothing to do with religion (noise, traffic, neighborhood character, etc.), they would have had a better chance of winning the case.
In other words ... Standing up there and complaining about the mosque on religious grounds basically guaranteed that the Muslims would win the case.
