A judge has upheld the summary prepared by Secretary of State Robin Carnahan for a potential ballot measure barring public funding for abortions and certain kinds of stem cell research.

Carnahan's wording had been challenged both by the sponsors of the proposed constitutional amendment and its opponents.

But Cole County Judge Patricia Joyce shot down all their arguments. Joyce ruled that Carnahan's wording is sufficient and fair and informs people of the probable effect of the initiative.

The measure is sponsored by the Missouri Roundtable for Life and is targeted for the 2010 ballot. The group said it is considering an appeal.
