The Supreme Court ruled yesterday that a bankruptcy court incorrectly granted Anna Nicole Smith over $400 million from the estate of her oil magnate husband J. Howard Marshall.

In the 5-4 ruling, the highest court held that the Constitution barred a California bankruptcy court from deciding a matter outside the scope of bankruptcy law.

The former Playboy Playmate married the billionaire Marshall in 1994 when she was 26 and he was 89. Marshall died in 1995 and left his entire estate to his son Pierce. Smith sued in response, but a Texas probate court granted the entire estate to Pierce Marshall.

Smith then made a similar claim against Pierce Marshall when she filed for bankruptcy in a California court. This time Smith won, and the bankruptcy court awarded her over $400 million.
