A former chief executive officer of the Ghana National Petroleum Corporation (GNPC), Mr Tsatsu Tsikata, has filed a suit at the Court of Appeal, challenging his sentencing to jail for five years in 2008.
In the suit, Mr Tsikata said that the verdict that led to his imprisonment was unreasonable and was not supported by evidence.
He said the trial judge erred in law in deciding that financial loss had been caused simply because payment of monies had been made by the GNPC, according to a report by the Daily Graphic.
The former GNPC CEO was found guilty of willfully causing financial loss of GH¢230,000 to the state through a loan that the GNPC guaranteed for Valley Farms, a private cocoa-growing company.
Mr Tsikata was unconditionally pardoned by former President J.A. Kufuor on his last day in office but he rejected the pardon and insisted that he would continue to pursue justice in the court of law.
