For SPSV vehicle licences, the licensing authority is NTA. For SPSV Driver Licences, it is An Garda Síochána. Legislation sets out that the licensing authority may;
“at any time, revoke a licence if it is satisfied that the holder of the licence is no longer a suitable person to hold a licence.”
The licensing authority will consider whether the holder of the licence has contravened any obligations or regulations under the Taxi Regulation Act 2013 or whether or not the licence holder has been convicted of any offence.
Also, the licensing authority will consider if the licence holder failed or refused to provide information required by the Act, any regulations under the Act, the terms or conditions of the licence, or supplied information that was false or misleading and which he or she should reasonably have known to be such.
The licensing authority will consider the need to ensure the safety and welfare of passengers in SPSVs and other road users, and consider any conduct by the licence holder “which calls into question the holder’s suitability to hold the licence”.
The licensing authority, if considering to revoke a licence, and where it is satisfied that all the required ‘elements’ have been met to support a revocation, but decides not to revoke the licence, it may, if it is satisfied that it is appropriate to do so—
Suspend the licence for a period not exceeding 3 months
Where appropriate, the licensing authority may elect not to revoke or suspend a licence and issue a notice to the licence holder of one of the following;
In all cases, any person who is the subject of one of these actions has the right to appeal to the District Court.
