Waste collection company Panda is trying to block proposals by Dublin's four local authorities to change the household bin collection system.
At the High Court today it claimed the measures amounted to an unlawful attempt to remove the competition currently provided by private waste collection operators.
Dublin's four local authorities want the collection of household waste, in designated areas, to be run by a single operator - either the local authority or a private company chosen following a tendering process.
In April, Panda secured leave in the High Court for a judicial review of this variation of its waste management plan, claiming the proposals would effectively remove competition from the market place.
Panda contends the councils are making the changes in order to control waste ownership and thereby ensure their planned incinerator at Poolbeg receives enough material.
Panda has developed a base of around 28,000 domestic customers in Dublin.
Its success recently led to Dún Laoghaire-Rathdown County Council announcing its intention to discontinue providing a waste collection service.
It is going to appoint a private contractor to collect black and brown bins, for organic waste, from its householders.
