A three-judge panel of the 9th U.S. Circuit Court of Appeals last month rejected Renzi's request to have that his 2013 convictions set aside. He argued the government didn't disclose that the FBI told a key witness he may be paid in exchange for testimony and other key facts.
That decision became final Thursday.
The appeals court upheld a Tucson federal judge's decision that said any missing disclosures would not have changed the trial outcome.
Renzi was released from federal prison in January after serving three years for corruption, money laundering and other charges.
