Werlein also dismissed charges against another executive, Daniel Bayly.
Earlier this week, Werlein granted a request by prosecutors to dismiss charges against another executive, Daniel Bayly.
Furst, Bayly and a third executive were convicted in 2004 of conspiracy and wire fraud. They're accused of helping push through Enron's sham sale to Merrill Lynch of three power barges moored off the Nigerian coast in 1999. The deal was struck to make the earnings of Enron's energy division appear larger.
Enron Corp. collapsed into bankruptcy in December 2001.
