A case against Galway-based bus company Citylink has been adjourned for hearing on 8 March.
Company officials were summoned by the Director of Public Prosecutions to appear before Galway District Court, charged with running an unlicensed express route between Dublin and Galway.
Citylink, which is owned by the Singapore-based global transport company, ComfortDelGro, is permitted to run a service with scheduled stops under the terms of an existing licence. But the Department of Transport says the company does not have a licence for a non-stop service.
An application by Citylink for a licence to run an express route is before the department for consideration.
The emergence of the new bus service in recent months has led to ongoing price wars on the Dublin-Galway route with rival operators, Bus Éireann and GoBus.
