The DPP decided to prosecute 612 people for domestic violence last year.
It has decided to take 2,000 people to court for the offence since 2019, according to freedom of information files.
The DPP opted to prosecute 629 people for the crime in 2021 - but only 252 two years earlier.
Criminal barrister and Fine Gael senator, Barry Ward, says it's normally a straightforward offence to bring to court:
It is only a difficult crime to prosecute when the victim feels like they cannot come forward and continue with the prosecution.
Very often, the problem with prosecuting domestic violence is that the complainant in the case withdraws the complaint.
That is about putting in place systems that reassures victims and reassures them that the process will respect the claim they made.
