Green Party TD Patrick Costello has told the High Court he is concerned investor court measures in the EU-Canadian trade deal (Ceta) for protecting Canadian investors in EU member states may impact on Ireland’s ability to introduce “much-needed” environmental regulation.

Mr Costello said he became aware of the Comprehensive Economic Trade Agreement in about 2016, when the Green Party was among a wide alliance of NGOs and community groups campaigning against it.
