Reliance on the Aarhus Convention in nuisance claims?

25 July, 2014

In court proceedings the usual rule is that the successful party is entitled to have its reasonable costs paid by the losing party. The Aarhus Convention is an EU Directive which entitles the court to limit the exposure to costs by a person who brings a claim but loses. When the Convention applies the Court can make a protective costs order so that if the person bringing the claim loses he only has to bear his own costs and the successful party also bears his own. The Convention applies to cases where the protection of the environment is in issue, to ensure claims that have a wider public benefit to the environment are not stifled. It is most commonly applied in judicial review cases but in Austin v Miller Argent (South Wales) Limited the Court of Appeal had to decide whether the Convention applied to a private action in nuisance.

The case concerned the operation of an open cast coal mine operated by Miller. Miller’s planning permission to operate a coal mine from the site was subject to certain conditions, to ensure the effects of mining activities on the environment were mitigated. Mrs Austin lived nearby and claimed that the operation of the mine was not in accordance with the conditions imposed in the planning permission and that it caused her a nuisance. She sought to apply the Aarhus Convention to give her costs protection in the proceedings, so that, if she were ultimately unsuccessful in her claim, she would not be ordered to pay Miller’s costs.

In the eyes of the Court of Appeal it would be wrong to restrict the application of the Convention to judicial review cases (which is an argument Miller relied upon). The Aarhus Convention is concerned with protection of the environment for the benefit of the public at large and while this lends itself to judicial review claims the wording of the Convention does not mean it could not apply to private nuisance claims provided (1) the nature of the complaint has a close link with matters of the environment that the Convention is concerned with and (2) the claim, if successful, confers significant public environmental benefits. The Court of Appeal were clear in their judgment that this finding is not a green light for Claimants to rely upon the Convention in all actions in nuisance and indeed the application in this case was unsuccessful as success (the Court of Appeal decided) would not yield sufficient public environmental benefit to justify protection of the Convention.

What circumstances might give rise to Convention protection in private nuisance actions remains to be seen but as a matter of principle the Court of Appeal has confirmed that the Convention applies to such cases as much as it does to judicial review. A transcript of the judgment is here:
