Case law

The Supreme Court's request for a preliminary ruling related to the interpretation of Arctics 4 and 19 of the Treaty on European Union (TEU) and Articles 13, 22, 23, and 30 of Directive 2008/50/EC on ambient air quality and cleaner air for Europe. The court also held that it was not for the courts to make such orders as they were inherently political and would involve decisions to be made about potentially huge sums of money to address the problems. So far as the third question was connected was concerned, the CJEU noted that an air quality plan should set out appropriate measures so that the period during which the limit values are exceeded can be kept as short as possible and may also include specific measures aimed at protecting sensitive population groups.
