“We raised the issue of the consideration of mitigation measures at the screening stage, where such measures are not integral to the project concerned, with the UK authorities directly. In response the UK authorities confirmed that they are seeking to provide clarification on the issue under a new Circular and accompanying guidance to be published, we would be informed, in the near future. The Commission has requested that the UK authorities provide a copy of the Circular and accompanying guidance once it is published. As noted previously, whilst the Commission assesses the extent to which it considers that obligations under EC legislation have been complied with, the final interpretation of such legislation is given by the European Court of Justice. As a result, the Commission welcomes any interpretation of obligations under EU legislation, in this case the EIA Directive, in view of the assistance this may offer to the competent authorities in the member states on the practical application of the Directive. Given the difficulties to which this issue has given rise in various cases in the UK courts to which you have drawn our attention, any interpretation by the court would be particularly useful. The Commission will not actively pursue infringement proceedings when a member state is aware of a problem and is seeking to address it: once the Circular and guidance is available, the Commission will be in a position to assess it in the light of the requirements of the EIA Directive. On the other hand the Commission recognises that inconsistencies may arise in the approach taken by the national courts in domestic cases and what the UK authorities proposes by way of guidance, and hence the value of a definitive ruling from the European Court of Justice to provide a clear interpretation for such cases in the future.”
