The Seanad is to begin public hearings today on how the National Anthem should be treated.
The copyright on the Anthem was previously held by the State but expired in 2012.
Copyright in songs usually last for the life of the composer plus 70 years.
Some, including Fianna Fáil Senator Mark Daly, want it brought back into copyright to avoid it being commercially exploited.
A public consultation process has been completed and the Seanad will prepare a report for the Government once the public hearings are finished.
