Attorneys for jailed Texas tycoon R. Allen Stanford on Wednesday were expected to begin their defense in his fraud trial after prosecutors rested their case following three weeks of testimony in support of their claims the financier was behind a massive Ponzi scheme that took billions from investors.

The presentation of Stanford's defense did not immediately begin as his attorneys were given an hour by U.S. District Judge David Hittner to decide how they would proceed.

"We've been in discussions with our client on what is wise, what the next step would be," said Robert Scardino, one of Stanford's attorneys. Scardino had initially asked for the rest of Wednesday to discuss trial strategy with Stanford but Hittner only gave them an hour.

The request by Stanford's attorneys came after Hittner denied their motion to dismiss all charges against the financier because prosecutors had failed to prove their case. Such motions are typically argued after prosecutors finish presenting a case and are usually denied.

Stanford's attorneys have previously said the financier planned to testify but have also indicated he has the right to change his mind. A gag order prevents defense attorneys and prosecutors from discussing the case.

Before resting, federal prosecutors methodically presented evidence, including testimony from ex-workers of Stanford's companies as well as emails, financial statements and other documents, that they allege show the flamboyant businessman orchestrated a 20-year scheme that bilked more than $7 billion from investors through the sale of certificates of deposit, or CDs, from his bank on the Caribbean island nation of Antigua. They allege Stanford lied to depositors by telling them their funds were being safely invested.

Defense attorneys have tried to show the financier was a savvy businessman whose financial empire, headquartered in Houston, was legitimate. They said he was trying to reorganize his businesses to pay back investors when authorities seized his companies.

The prosecution's star witness — James M. Davis, the former chief financial officer for Stanford's various companies — told jurors his ex-boss perpetrated the fraud so he could funnel money to pay for various businesses, most of which failed, and to pay for a lavish lifestyle that included yachts and private jets.

Stanford' attorneys accused Davis of leading the fraud and questioned his character, including highlighting extra marital affairs he's had. They also accused him of lying so he could get a reduced sentence. Davis pleaded guilty to three fraud and conspiracy charges in 2009 as part of a deal he made with prosecutors for a possible reduced sentence.

Stanford is on trial for 14 counts, including mail and wire fraud, and could be sentenced to more than 20 years in prison if convicted. Stanford was once considered one of the U.S.'s wealthiest people, with an estimated net worth of more than $2 billion. He's been jailed without bond since being indicted in 2009.
