The Government is considering stricter penalties for people who lie under oath.
The Justice Minister will present his Cabinet colleagues with amendments that would make perjury easier to prosecute.
Charlie Flanagan wants to use new laws to tackle insurance fraud in particular.
He is proposing to amend a bill - brought forward by Pádraig Ó Céidigh and other independent senators - to put perjury on a statutory footing.
It would increase the penalties to a maximum €100,000 fine or 10 years in prison on conviction on indictment.
During a Seanad debate in April, independent senator Michael McDowell was among those who voiced support for new rules about perjury.
He argued: "In the current climate, everyone is talking about personal injuries, fraud and all of that. Perjury is a wider issue than that.
"People can tell appalling lies in commercial and matrimonial cases and many other areas and do great damage to others, either personally or financially, or they may amass substantial gains for themselves by their behaviour."
Minister Flanagan, meanwhile, said he supported the 'general principle' of the bill, and was seeking amendments in a bid to "further develop and strengthen" the proposed legislation.
