The DPP has lodged an appeal against the leniency of the jail sentence handed down to Kerry farmer Michael Ferris.
The 63-year-old of Rattoo, Ballyduff was convicted of the manslaughter of Anthony O'Mahony following a long row over a crowbanger.
Michael Ferris told gardai he snapped when he used a large farm vehicle with prongs to drive into Anthony O'Mahoney's car in April 2017.
He described the 73 year old's 30 year use of a crowbanger - which is a loud device used to scare crows.
Ferris went on trial for murder but was found guilty of the less charge of manslaughter.
Earlier this month, he was jailed for 6 years with one suspended for the killing.
Anthony O'Mahony's family was angry at the sentence saying the 73 year old was taken from them in the most brutal and violent way possible.
It's now emerged the DPP has lodged an appeal against the undue leniency of it.
