(iii) any failure to take any action,

pursuant to a law of the State that gives effect to—

(I) a provision of Council Directive 85/337/EEC of 27 June 1985 to which Article 10a (inserted by Directive 2003/35/EC of the European Parliament and of the Council of 26 May 2003 providing for public participation in respect of the drawing up of certain plans and programmes relating to the environment and amending with regard to public participation and access to justice Council Directive 85/337/EEC and 96/61/EC) of that Council Directive applies,

(II) Directive 2001/42/EC of the European Parliament and of the Council of 27 June 2001 on the assessment of the effects of certain plans and programmes on the environment, or

(III) a provision of Directive 2008/1/EC of the European Parliament and of the Council of 15 January 2008 concerning integrated pollution prevention and control to which Article 16 of that Directive applies; or

(3) The Court may award costs against a party in proceedings to which this section applies if the Court considers it appropriate to do so—

(5) In this section a reference to ‘the Court’ shall be construed as, in relation to particular proceedings to which this section applies, a reference to the High Court or the Supreme Court, as may be appropriate.”.
