The U.S. Supreme Court has agreed to hear an appeal of Jeff Skilling's convictions in the Enron bankuptcy.

Former CEO Jeffrey Skilling was convicted on 19 charges relating to energy firm Enron Corp.'s collapse.

Skilling was the former energy giant's chief executive officer when it collapsed in 2001, wiping out hundreds of millions in shareholder equity and kicking off a slew of criminal and civil proceedings.

In May 2006, Skilling was sentenced to 24 years and four months in prison for his role in orchestrating the events leading to one of the biggest corporate scandals in U.S. history.

The court said Monday it will hear Skilling's appeal of lower court rulings that upheld all 19 of his 2006 convictions of conspiracy, securities fraud, insider trading and lying to auditors involving the 2001 collapse of Enron.

The court could consider throwing out the convictions.

Skilling's co-accused, Enron founder and chairman Kenneth Lay, was found guilty of six counts of fraud and conspiracy in the matter.

But since he died of heart failure in 2006 before being sentenced and before he had a chance to appeal, a federal judge ordered his convictions vacated — effectively wiping clean his criminal liability.
