JEFFERSON CITY, Mo. (AP) — Efforts to put a new Missouri law banning abortions at eight weeks of pregnancy to a public vote have hit another roadblock.

Cole County Circuit Judge Daniel Green on Thursday tossed a lawsuit by prominent Republican donor David Humphreys seeking to force Republican Secretary of State Jay Ashcroft to approve his referendum petition. Green dismissed a similar ACLU of Missouri lawsuit on Wednesday.

Acting Executive Director Tony Rothert says the ACLU appealed.

Humphreys and the ACLU are seeking to put the abortion law to a public vote in hopes of repealing it.

The law does not include exceptions for rape or incest.

Humphreys and the ACLU sued when Ashcroft rejected their referendum petitions.

Rothert says he expects the case will ultimately end up before the Missouri Supreme Court.
