In 2007, a 17-year-old girl living in State care became pregnant and discovered that her unborn child had a life-limiting condition.
The HSE tried to prevent her from travelling to have an abortion.
The girl took the HSE to court and that was when she became known to the public as Miss D - and entered the eye of a media storm.
Every day of the case, this girl arrived at the High Court and walked past protesters who felt they had the right to wave posters in her face, hoping to influence her decision.
At the time, the case raised a hugely contentious constitutional issue. It also challenged legal limits on the right of women to travel and to access information and abortion services overseas.
Ultimately, the court ruled that Miss D did have the right to travel.
At the centre of that case was a girl who had just turned 17, a person whose life was laid out before the courts, who barely understood what was happening to her, and who was pregnant with a much-wanted baby with a tragic diagnosis.
Miss D is Amy Dunne and, on Claire Byrne Live tonight, she will talk about the impact that experience has had on her life and where she is now.
Amy has made a very special film for us telling the story of that time, and what it was like to live through it.
Amy will also join us live in the studio to tell us how she is now, what her ambitions are for the future, and how she feels that an experience like that shouldn't define her and her life.
She will be joined by RTÉ's Legal Correspondent Orla O'Donnell who covered the case in 2007. Ms O'Donnell also recently made a programme with Amy for TG4.
Claire Byrne Live will be broadcast tonight at 10.35pm on RTÉ One.
