The lawsuit, claiming First Amendment violations, is filed in U.S. District Court for Lisa Wilson, Danny Wilson, Kathryn Wuest, Kyle Riley and Amanda Johnson.
“Recently, a federal court in Virginia found that a local politician had violated the First Amendment when she temporarily banned a constituent from commenting on her Facebook page. This case raises substantially similar issues,” Joshua Engel, the lawyer who filed the lawsuit, said in comments posted on his law firm’s website.

This morning, Lisa Wilson said she also had been unblocked, but that others were still unable to comment on the site.
Also this morning, Mike Stine, who is not a party in the lawsuit, indicated he had been unblocked since the lawsuit was filed.
"Also thanks for unblocking me, I know it took some people to file a lawsuit so that I can contact you, one of our elected trustees," Stine said in a post on the Facebook page in question.

This morning, Engel indicated the lawsuit would not be withdrawn because of Wallace unblocking critics.
“We won’t be dropping the suit because we can’t confirm what he has done to unblock people and, more importantly, we need to make sure this is not done in the future,” Engel said this morning via email.
Wallace did not respond to requests for a response and has not responded to the lawsuit, filed on Sept. 5.
