The National Roads Authority has said it is seeking to take court action against a number of road toll operators for failing to reduce toll charges.
In a statement, it said there was a commercial disagreement between the National Roads Authority and a number of toll operators in relation to the applicable 2011 toll rates.
The NRA said as of January 2011, five tolling operations - M1-Dundalk, M4-Kilcock/Kinnegad, M6 Galway/Ballinasloe, M8-Fermoy and N25-Waterford City Bypass - were required to lower their tolls.
To date it says only one toll operator, M6 Galway/Ballinasloe, has lowered its tolls.
According to the NRA, those toll operators that have not reduced the toll rates have put forward a different interpretation of the toll by-laws to that of the NRA.
The NRA is now taking the necessary steps to obtain a definitive determination on this matter in the courts.
The NRA also confirmed that the toll rates applied on the M3 Clonee-Kells, M7/M8 Portlaoise Bypass, Limerick Tunnel, M50 eFlow and Dublin Port Tunnel along with the M6 Galway/Ballinasloe are not the subject of a disagreement.
In a statement, the Celtic Roads Group said it agreed with the NRA that clarification was needed, and said it would abide by the outcome of the courts.
