Former assistant Dublin city and county manager George Redmond has been granted leave to enter new evidence in his appeal against his conviction for corruption.
Redmond claims the bank records of car dealer Mr Brendan Fassnidge do not appear to support the claim that the now-retired planner accepted a £10,000 bribe in the 1980s.
The records were not entered into evidence during the trial at which Redmond was convicted for corruption last December.

The Court of Criminal Appeal today ruled that Mr Fassnidge's bank statements between March 1st, 1988, and April 7th, 1988, should be entered into evidence in Redmond's appeal.
The court ordered the manager of Bank of Ireland's Blanchardstown branch, Mr Padraig Brennan, to appear on Friday.
The three-person panel of judges - which consisted of Mr Justice Quirke, Mr Justice O'Donovan and chaired by Ms Justice Denham - ruled that failure to hear the evidence "could give rise to an injustice".
Redmond is appealing his conviction on a number of legal grounds and was today also granted leave to include a claim of unsafe conviction.
The DPP had argued that Redmond's defence team had access to the statements during the trial but had not chosen to enter them into evidence.
But in an affidavit yesterday, Ms Clare O'Callaghan, solicitor for Redmond, said that during prosecution's disclosure of evidence it was made clear there were no records for Mr Fassnidge's accounts with Bank of Ireland, Blanchardstown, where he withdrew the £10,000 used to allegedly bribe Redmond.
It was not possible to show therefore whether the money had been withdrawn, Ms O'Callaghan argued.
The Court today found: "It was clear from the general run of the case that the parties commenced with the common view that there were no bank records because of the lapse of time. . . . What is sought to be available is both admissible, relevant and material to the principle issue in the trial."
Redmond's appearance before the Mahon tribunal was delayed under instruction of the chairman until after today's hearing. Judge Mahon will decide later today on whether to ask him to appear tomorrow as scheduled.
