Several Florida voters are suing county elections officers, the Florida secretary of state and others in a bid to strike the Amendment 4 abortion-rights initiative from the state’s November ballot and block the counting of ballots in favor of the measure.

The campaign manager for Amendment 4 called the litigation, which was filed Oct. 16 in the Ninth Circuit Judicial Court in Orange County, a desperate attempt to undermine Floridians’ right to vote on the initiative.

The lawsuit argues that widespread irregularities took place in the signature-gathering campaign to place Amendment 4 on the ballot. The measure would provide a state constitutional right to abortion prior to viability of the fetus or when “necessary to protect the patient’s health, as determined by the patient’s health care provider.” It would also overturn the state’s current six-week abortion ban.
