Attorney Marc Rosenthal has filed an appeal with the U.S. Court of Appeal's Fifth Circuit.
According to court documents, Rosenthal is appealing his 20-year sentence and conviction.
Rosenthal was sentenced on December 03, 2013 to 20 years in federal prison, and he was ordered to pay more than $12 million dollars in restitution.
Rosenthal was convicted of being the ringleader in the "cash for court favors" scandal involving former 404th State District Judge Abel Limas. Judge Andrew Hanen, based in Brownsville, sentenced Rosenthal after he was convicted in Cameron County's "cash for court favors" scandal.
Rosenthal was convicted of one count of conspiracy to violate the Racketeering Influenced Corrupt Organization (RICO) statute, five counts of mail fraud, three counts of tampering with witnesses or proceedings, one count of extortion; and, three counts of mail fraud, aiding and abetting and deprivation of honest services.
A federal judge granted a change of venue to Corpus Christi due to wide publicity surrounding his case in the Rio Grande Valley.
