Gemma O'Doherty and John Waters have been ordered to pay the costs of two days of litigation in the High Court.
It's after they launched a legal challenge to the restrictions brought in to combat the spread of Covid-19.
Last month, Gemma O'Doherty and John Waters were refused permission to challenge the emergency legislation that introduced the COVID-19 restrictions.
Today the High Court ruled that they must pay the costs of this failed attempt.
O'Doherty and Waters had resisted this as they felt the proceedings were "in the public interest."
In his judgement, Mr Justice Charles Meenan said that the issues raised by the restrictions imposed are important matters of public interest.
However, the manner in which they conducted their proceedings, and the fact that only held regard to their own opinions were not.
He concluded that there were no grounds for them not to pay the costs of the Health Minister and Oireachtas.
These will be limited to the costs associated with the hearings held on the 5th and 6th of May.
