Lisa Smith has won an appeal against a decision to exclude her from the UK.
The 39-year-old from Dundalk is due to go on trial in Dublin next year, charged with membership of the Islamic state.
She had been barred from entering the UK by the British Home Secretary.
Today the Special Immigration Appeals Commission, sitting in London ruled in Ms Smith's favour.
Her solicitor Darragh Mackin welcomed today's decision, which he says will now reinstate his client's basic rights to travel to the North of Ireland.
Mr. Mackin, said:
“Today’s ruling is hugely significant for the upholding of basic human rights principles which include the right to be free from discrimination. The decision to exclude our client was discriminatory and contrary to the basic principles underpinning the Good Friday Agreement.
As an Irish citizen who resides in a border town, it was always asserted that to restrict her from travelling across the border was unlawful and could not be stood over. We warmly welcome the Court’s determination today which will now reinstate our client’s basic rights to travel to the North of Ireland at her convenience.”
