Northern Ireland's strict abortion law breaches the UK's human rights commitments, the High Court in Belfast has ruled.
The case was brought by Sarah Ewart who in 2013 was forced to travel to England for a termination after being told her unborn child had no chance of survival.
She had backed a previous challenge taken by the Northern Ireland Human Rights Commission.
Mrs Justice Siobhan Keegan said Sarah Ewart was a victim.
"Her personal testimony is compelling," she said.
The judge followed the ruling of the Supreme Court that abortion law in Northern Ireland was incompatible with Article 8 of the European Convention on Human Rights.
She said Ms Ewart had legal standing to challenge the law.
The judge will hear further submissions before deciding what action to take.
She said Ms Ewart had been affected by the current law.
The judge said: "She has had to modify her behaviour in that she could not have medical treatment in Northern Ireland due to the risk of criminal prosecution.
"She may be actively affected in the future.
"In my view her personal testimony is not disputed."
Ms Ewart said: "It is a massive emotional relief.
"This has not been an easy journey."
She added: "It is a massive victory.
"It has been a massive stress emotionally on the family but six years later let's enjoy today."
