The High Court has granted leave to Greyhound Recycling to apply for an interlocutory injunction to restrain protesters from unlawful picketing.

Greyhound Recycling claims there is a widespread and organised campaign to block bin lorries and prevent waste from being collected.

In an affidavit submitted to court today, Greyhound Recycling and Recovery Chief Executive Michael Buckley said blockading is occurring at the premises and at various locations around the city on a daily basis.

He said "such is the evolving scale and extent of the activity that garda resources are now being stretched".

He said 15% of bins from 1,200 customers have been affected.

Mr Buckley said that since Friday waste has been collected from approximately 900 of those customers, at a considerable extra cost to the company, but it has not been possible to collect rubbish from 300 customers in Cromcastle in Coolock.

In his affidavit, Mr Buckley said the intention is not to restrain lawful picketing.

He said there have been some dangerous incidences.

He referred to one instance when a child, aged around three or four-years-old, was led in front of a heavy vehicle which was attempting to leave the company's premises on Crag Avenue.

He said the child was then lifted by a protester and placed directly in front of the vehicle.

Mr Buckley said unless the court grants a order the company and its customers will suffer economic harm and extreme inconvenience.

He also said the uncollected rubbish in some areas is of grave concern and poses a health and safety risk.

During an ex parte application today, barrister Louis McEntagart BL, representing Greyhound, applied for leave for an interim interlocutory injunction to be heard on Friday and that 17 individuals be served with notices of the motion.

Ms Justice Mary Irvine agreed to the reliefs sought and will hear the case on Friday.
