North Carolina lawmakers are holding a special session Wednesday in an attempt to block an LGBT protections ordinance in Charlotte from taking effect on April 1.

Earlier this month, city leaders approved the ordinance which prohibits discrimination based on sexual orientation and gender identity in public accommodations, vehicles for hire and government contracting.

State lawmakers were not scheduled to return to Raleigh until April 25. Special sessions cost $42,000 a day.

Republican House Speaker Tim Moore said that he hopes the special session will last one day and that it is necessary to protect women and children.

“When a local government goes on such a radical course and a reckless course, we in the General Assembly I think not only have the authority but actually the duty to do something about it, and in this case we're going to,” Moore is quoted as saying by the AP.

Opponents of the measure claim that they fear the ordinance will allow men posing as women to gain access to women's restrooms.

Lawmakers are expected to introduce legislation that would block local governments statewide from approving similar measures.
