WASHINGTON (AP) - A lawyer for deceased former Playmate Anna Nicole Smith has told the Supreme Court her estate deserves some of the $1.6 billion estate of her late Texas billionaire husband.

The Supreme Court is now consideringTuesday arguments on whether Smith's estate should get part of the fortune left behind by J. Howard Marshall.

The elderly Marshall's will left nearly all his money to his son, E. Pierce Marshall, and nothing to Smith, who said her husband of 14 months promised to leave her more than $300 million.

But a federal appeals court sided with a Houston jury that said Marshall was mentally fit when he left his estate to his son and nothing to Smith. She had wanted the courts to accept a bankruptcy court ruling giving her roughly $89 million.
