On June 23, 2016, supporters of Bernie Sanders sued the Democratic National Committee over a belief that the national party had not been neutral in the race for the Democratic presidential nomination. On August 23, a hearing was held in the case, Wilding v DNC Services, southern district of Florida, 0:16cv-61511. But the only issue was whether the plaintiffs had properly served the defendants.
During the two-hour hearing, Judge William Zloch permitted the plaintiffs to show a video film clip of the server serving someone in the party office. The party argues that the person who received the papers was not authorized to accept the papers. The day after the hearing, both sides submitted briefs on the service issue. Supporters of the lawsuit have a facebook page which has more detail.
