LITTLE ROCK, Ark. — Supporters of a ballot measure that would place limits on damages in medical lawsuits have asked Arkansas’ highest court to dismiss two efforts to remove it from the November ballot.

Health Care Access for Arkansans argued in motions filed Friday that groups challenging the proposal have no constitutional right to sue to kill the proposal.

One challenge says petition signatures are invalid while another says the language to be presented to voters is flawed.

The motions come a day after a retired judge appointed by the state Supreme Court to review petitions said all signatures submitted could be disqualified if justices find in one of the challenges that the campaign did not properly confirm that canvassers passed criminal background checks.

Supporters say taxpayers can challenge ballot measures by voting.
