RENO, Nev. (AP) — In a case watched by national anti-abortion organizations, a Nevada couple is trying to block a judge from holding hearings that it fears could result in the termination of their mentally disabled daughter’s pregnancy.

The couple filed a motion asking the Nevada Supreme Court to halt the proceedings by Washoe County District Judge Egan Walker, arguing he lacks authority to make such a decision for their 32-year-old daughter, who has the mental capacity of a 6-year-old.
