MADISON, Wisconsin (AP) - A mother and father who prayed instead of seeking medical help as their daughter died in front of them were properly convicted of homicide, the Wisconsin Supreme Court ruled on Wednesday.

Eleven-year-old Madeline Kara Neumann died of undiagnosed diabetes on Easter Sunday in March 2008 at her parents' Weston home. Prosecutors said her parents, Mr Dale and Mrs Leilani Neumann, ignored obvious symptoms of severe illness as their daughter became too weak to speak, eat, drink or walk, choosing to pray rather than take her to a doctor. After the girl died, Mrs Leilani Neumann told police God would raise the child from the dead.

Doctors testified that the child, known as Kara, would have had a good chance of survival if she had received medical care, including insulin and fluids, before she stopped breathing.

Prosecutors charged the couple with second-degree reckless homicide. Separate juries convicted them in 2009. They each faced up to 25 years in prison, but a judge instead ordered them to each serve a month in jail every year for six years, with one parent serving every March and the other every September.

The couple's attorneys argued that Wisconsin law protects people from being charged with child abuse if they provide spiritual treatment for a child in lieu of medical assistance. They contended the law protects parents from criminal liability through the point of creating a substantial risk of death, making it difficult to know when a situation has become so serious that parents who stay with prayer healing become criminally liable. State attorneys countered that parents are immune from child abuse charges but not homicide counts. Once they realise a child could die, their immunity ends, they argued.

More than a dozen US states have some form of legal protection for parents who choose prayer healing for their children over conventional medical attention. But they've been wrestling for years with how far those protections go.

Wisconsin's 3rd District Court of Appeals sent the Neumann's appeal straight to the state Supreme Court without ruling on it, calling the case unique.

In a 6-1 decision, the state Supreme Court found criminal immunity for treatment by prayer has clear limits and that the Neumanns crossed the line.

"The juries could reasonably find that by failing to call for medical assistance when Kara was seriously ill and in a coma-like condition for 12 to 14 hours, the parents were creating an unreasonable and substantial risk of Kara's death, were subjectively aware of that risk, and caused her death," Chief Justice Shirley Abrahamson wrote for the majority.

Justice David Prosser, the lone dissenter, called the case "a tragedy in virtually every respect" and acknowledged the Neumanns' reaction to Kara's illness was so outside most parents' normal behavior that it's hard for anyone to identify with them or understand their thinking. He maintained state law is unclear on how far immunity for prayer treatment goes.

The Neumann's attorneys didn't immediately return telephone messages left for them early Wednesday morning.
