A private inland waterways jetty on the Liffey has caused unrest among local anglers, the Circuit Civil Court heard on Thursday.

According to The Irish Times, the Dublin and District Salmon Anglers' Association is seeking a court order against entrepreneur David Wright - of the noted Howth family of fish suppliers - who they claim is 'disturbing the calm of the river'.

The group also accused him of trespassing on a stretch of river leased to them by Dublin City Council for exclusive fishing rights, and were obliged by their lease to protect the fishery.

It is alleged that Wright built a double jetty with retractable pontoons at the rear of two houses he owns on the riverbank in Chapelizod. 

His barrister Edward Farrelly told the court he would challenge Dublin City Council's right to lease the river.
