Proceedings in the Supreme Court have been filmed and broadcast for the first time in the history of the state.
Television cameras were allowed in to film two judgments being handed down and were broadcast on RTÉ News Now and are now available to view on the RTÉ Player.
It is the first time any recording or transmitting of proceedings in a court case has been permitted.
Chief Justice Frank Clarke said it would be a way of demystifying the courts process.
He described it as a "baby step" which could lead to wider filming of the courts in the future.
In the first case the court dismissed the challenge by an Irish man to his extradition to the US to face 51 counts of mortgage fraud.
Patrick Lee from Newtown, Co Kildare, had claimed that he should not be extradited because he could be prosecuted for the same offences in this country.
The five judges unanimously dismissed his appeal.
The second case concerned a man who suffered significant abuse after being misdiagnosed with an illness as a very young child. The abuse happened after he was sent by one institution to a nursing home to be treated.
The nursing home was not covered under the Residential Institutions Redress Act.
The High Court found he should be compensated for what happened in the second institution. The Appeal Court ruled he should not be.
In a majority ruling of four judges to one, the Supreme Court overturned the Appeal Court decision and ordered the matter to go back to be reviewed again in accordance with the ruling.
Mr Justice Donal O'Donnell dissented.
It is hoped further proceedings from the Supreme Court will be broadcast over the next few months.
Eventually it is hoped arguments from lawyers will be broadcast. In the future the project may be widened out to include Appeal Court rulings.
The Chief Justice said the televising of proceedings in criminal cases was still "a long way off".
