LEgeslative antecedents
State case
CC v Ors
Facts:
The applicant (CC) was charged with four counts of unlawful carnal knowledge
The complainant was under 15 years of age.
CC claimed he made a bona fide mistake about the girl’s age, believing she was over 15.
The trial judge (Smyth J.) held the offence was one of strict liability—meaning mistake as to age was no defence.
The case went to the Supreme Court, which initially upheld this interpretation.
Held:
✅ Majority (Geoghegan, Hardiman, Fennelly, McCracken JJ):
Strict liability applied—no defence of mistake as to age.
The legislative history showed that the Oireachtas deliberately removed the defence of mistake for girls under 15.
However, the majority also held that this interpretation of s.1(1) was unconstitutional:
It criminalised a mentally innocent person (no mens rea), violating rights under Article 40.3 of the Constitution (liberty, dignity, and good name).
The law failed to respect fundamental rights and imposed life imprisonment without proving moral guilt.
❌ Dissent (Denham J.):
Denham J. argued that s.1(1) should be interpreted as requiring mens rea.
Therefore, a mistake as to age could be a defence.
This interpretation would avoid the constitutional issue by preserving fairness and preventing unjust punishment.
