UK government correspondence quoted by the Guardian – Ash dieback: government claimed its ‘hands were tied’ on import ban, 9 November 2012 – suggests EU rules hampered measures at national level to counter ash dieback. In fact, each member state has the right to introduce national emergency measures to protect themselves against imminent danger. There is no EU rule that prevents them from doing this. Member states have the obligation to inform immediately the Commission and other Member States. The European Commission can trigger a procedure for action at European level only after it has received such notification from a member state. The Commission began its procedures on regulating Chalara fraxinea – the pathogen behind the latest outbreak – as soon as it received a request, i.e. on 29 October 2012.
