Greenberg Traurig is asking a Dallas federal judge to dismiss an allegation that the law firm aided and abetted R. Allen Stanford in his massive Ponzi scheme, contending that the claim under which it was sued no longer exists in Texas.

The law firm was originally sued in a 2012 lawsuit before U.S. District Judge David Godbey by Ralph Janvey, a court-appointed receiver tasked with recovering $7 billion in funds swindled by Stanford, a former Houston financier found guilty of 13 fraud counts by a federal jury and sentenced to 110 years in prison.
