JEFFERSON CITY (AP) – New arguments are being raised against a proposed Missouri constitutional amendment that would enhance the right to bear arms.

A legal challenge has claimed the summary approved by the Legislature for the Aug. 5 ballot measure is insufficient and unfair. Last week, an attorney for those challenging the measure asked a Cole County judge to rewrite the summary.

But now, attorney Chuck Hatfield has revised that request to instead ask the judge to send the measure back to the Legislature for a new summary. He contends it would violate the constitution’s separation of powers for a judge to rewrite a legislative measure.

Hatfield is representing a gun-control activist and the St. Louis police chief.

Referring the measure back to lawmakers could knock it off the ballot, because they aren’t in session.
