The Rape Crisis Network Ireland (RCNI) has called on the next government to commit to holding a referendum on child protection before Christmas.
On the first anniversary of the statutory rape crisis, the RCNI said that children and young people are "still exposed to a weakened defence against sexual predators".

RCNI executive director Fiona Neary said: "It is with regret that we find ourselves facing the first anniversary of the statutory rape crisis with the damage not reversed.
"We call on politicians across the board to commit to a priority time frame for the holding of the constitutional referendum on child protection".
The network also said that latest figures show a 47.4 per cent fall in reports of unlawful sex compared to the previous year.
According to the Dublin Rape Crisis Centre, the first half of 2006 saw 39 cases of unlawful carnal knowledge reported to the gardaí, but the second half of the year, after the May crisis, saw just 20 cases were reported.
The crisis arose when a number of convicted child sex offenders were freed from prison because of a loophole in the law.
The Supreme Court struck down Section 1 (1) of the 1935 Criminal Law (Amendment) Act when a case was brought by a young man who had consensual sex with a 14-year-old girl who told him she was 16. He was 18 at the time.
He argued the law was unconstitutional because it was not open to him to claim he honestly believed she was older.
Among those freed was a man (41) jailed for unlawful carnal knowledge of a 12-year-old girl whom he plied with alcohol. The following day he was re-arrested.
Within days, emergency legislation was rushed through the Dáil and signed into law.
