The High Court has refused an application by former Fine Gael TD Liam Cosgrave for access to some documents related to his criminal trial on corruption charges.
Mr Cosgrave and businessman Jim Kennedy made applications as part of their separate High Court cases aimed at preventing their trial going ahead later this year.
The main judicial review proceedings aimed at halting the trial will begin next week, but in the meantime the court has ruled they were not entitled to certain documents related to the case.
However Mr Justice Hedigan ruled Mr Kennedy should have access to some correspondence referred to in Garda statements.
The records sought relate to key prosecution witness Frank Dunlop.
They also sought correspondence between the DPP, the National Bureau of Criminal Investigation and the Criminal Assets Bureau.
At next week's case, Liam Cosgrave will argue the decision to prosecute him for corruption is an abuse of process.
His lawyers say he pleaded guilty to one charge in 2005 and believed that was the end of the matter.
They claim the current criminal charges are based on the same information given by Mr Dunlop prior to the 2005 case.
The 55-year-old former TD, senator and councillor of Merrion Park, Blackrock, is charged with receiving corrupt payments in 1992 and 1997 in relation to the rezoning of land.
Jim Kennedy, Queensway Quay, Gibraltar, is facing 16 charges of making corrupt payments to politicians relating to rezoning motions.
The criminal trial is due to being next October.
