In April 2007, Bloomfield attracted attention and some controversy when the city council voted unanimously to erect a stone monument of the Ten Commandments at the city hall. Two residents sued the city in 2012 "alleging it violated their constitutional rights and represented a government endorsement of religion". In August 2014, a federal judge ruled the monument must be removed. The city's response to the lawsuit was that it was a local group that paid for the memorial and they had added a disclaimer. A district judge decided that a "reasonable observer would interpret the monument as the government endorsing a religion". The ACLU became involved and the city asked the Supreme Court to hear the case, and was refused. The city owes court fees of $700,000 to the ACLU and the monument was moved to "property owned by a Baptist church. The city has been looking for outside funds to pay the fee, but in June 2018 it released its 2019 budget which calls for "paying $233,000 toward the money it owes from the... lawsuit". The city has until 2021 to pay the amount in full. Hemant Mehta stated that the "city officials were goaded by the Christian Right into fighting back. "
