The Supreme Court will decide whether the estate of Anna Nicole Smith should get part of the fortune left behind by the elderly Texas billionaire whom Smith married in the mid-1990s. The justices on Tuesday decided to reconsider an appeals court ruling against Smith's estate, which wants to capture some of the $1.6 billion estate of her husband, J. Howard Marshall, who died in 1995.

Marshall's will left nearly all his money to his son, E. Pierce Marshall, and nothing to Smith. The younger Marshall died in 2006 and Smith died of a drug overdose in 2008.

Smith challenged the will, claiming that her husband promised to leave her more than $300 million above the $7 million in cash and gifts showered on her during their 14-month marriage.

But the 9th U.S. Circuit Court of Appeals sided with a Houston jury that said Marshall was mentally fit and under no undue pressure when he wrote a will leaving nearly all of his $1.6 billion estate to his son and nothing to Smith.
