The man, who cannot be named for legal reasons, was found guilty in March of 74 charges of abuse on dates between October 1994 and July 2012.
The Central Criminal Court heard the abuse began at their Dublin home in 1994 when the eldest victim was 9 years old.
Ms Justice Margaret Heneghan declared the Tipperary man a sex offender and praised the victims as “persons of very great courage and determination”. Victim impact statements from the three sisters were read out in court today.
The judge described the man’s offences as “an exploitation of weak and defenceless children” and said his behaviour was “abhorrent and evil” in this “campaign of rape and sexual abuse” in which he “abused his power in the house”.
The court heard that the man has 57 previous convictions, mainly for road traffic offences. He has no previous convictions for sex crimes.
The judge said the man showed no remorse, that the crime was planned and pre-meditated and said it was difficult to “discount the sentence in any meaningful way”.
She noted that defence said the man’s wife still stands by him.
He was sentenced to 17 years in jail.
