The former Dublin Assistant City and County Manager, George Redmond, has been found guilty on two counts of corruption.
He has been remanded in custody for sentencing on 17 December.
The jury in the Dublin Circuit Criminal Court took over seven hours to reach their majority verdicts on both charges.
Redmond, who is 79, had denied the two charges that he received £10,000 as a bribe from garage owner Brendan Fassnidge relating to the sale of a right of way from Dublin County Council at the Lucan by-pass.
The Minister for Justice, Michael McDowell, has congratulated the garda officers in charge of the case for their 'very successful' investigation.
