A former CIE bus driver is challenging his conviction and 13-year sentence for soliciting two undercover gardaí to import cocaine from Brazil.
Sunny Idah, who had addresses in London and at Lipton Court, Temple Bar, Dublin was convicted at Dublin Circuit Criminal Court last year on two charges dating back to September 2010.
Sunny Idah was described at his trial as being part of an international drug operation.
He used the name Teamor while solicting two undercover gardaí to travel to Rio de Janeiro where, for €5,000 a head, they were each to swallow a kilo of cocaine pellets for import back to Ireland.
The investigation was initiated by a tip-off from an undercover Swiss police agent posing as a drugs supplier.
The 37-year-old, who has dual Irish and Nigerian citizenship, was handed down a 15-year sentence with two years suspended.
He is now challenging his convictions for solicitation at the Court of Criminal Appeal.
