"A Texas court has overturned the conviction of former House majority leader Tom DeLay in a money-laundering case...."

Insufficient evidence. 

DeLay was sentenced to three years in prison on a conspiracy charge and five years for money laundering. He remained free while he was appealing his case. For years, DeLay had maintained his innocence and denounced what he called the "criminalization of politics."

In the appellate court's majority opinion, the judges said that "the evidence shows that the defendants were attempting to comply with the election code limitations on corporate contributions."
