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.
Mr Justice Meenan ruled the lay litigants' failure to consider legal arguments put forward in court meant the proceedings were "very far from being in the public interest".
He ordered them to pay the costs incurred by the Oireachtas and the Minister for Health.
Gemma O’Doherty and John Waters will have to pick up the considerable bill for their two-day High Court hearing last month. The pair failed to convince the court to allow them to take a judicial review over the lockdown laws, and have now been ordered to pay all the legal costs.

Last month, Ms O'Doherty and Mr Waters were refused permission to challenge the emergency legislation that introduced the COVID-19 restrictions.
They wanted the High Court to allow them bring a judicial review, as part of an attempt to have the laws quashed.
In ruling against their application for a full judicial review, Mr Justice Meenan said their claims were not arguable.
In his judgement, Mr Meenan stated: "In court, the applicants gave unsubstantiated opinions, speeches, engaged in empty rhetoric and sought to draw an historical parallel with Nazi Germany.
"Such a parallel is both absurd and offensive.
"Unsubstantiated opinions, speeches, rhetoric and a bogus historical parallel are not substitutes for facts".
