The Court of Appeal will on Tuesday continue hearing the case involving Senior Superintendent of Police Harry "Bungles" Daley.
His attorneys, who started submissions Monday, argued that the senior cop was not given a fair trial when he was convicted on corruption charges four years ago.
SSP Daley is fighting his conviction and an 18-month prison sentence handed down in 2009.
The attorneys argued that he was robbed of a fair trial, as prosecutors failed to disclose information on the recording devices and computer used to capture the crime, in an operation by the Anti-Corruption Branch.
They contend that the law of disclosure is clear and they should have been given access to the devices.
Prosecutors objected to the request, relying on public interest immunity.
Defence attorneys further argued that they were denied access to the criminal record of the main witness, who was granted asylum in England.
SSP Daley became the most senior cop to be convicted of corruption when he was convicted for collecting money from businessman Tafari Clarke in a protection racket.
He strongly denied the allegations and argued that the money he collected was a debt owed by the family of the main witness.
