Judicial review – Conservation of wildlife – Licensing system – Restriction on use of licences permitting control of pest species. Court of Session: Refusing a judicial review petition seeking reduction of decisions of Scottish Natural Heritage restricting the use of the petitioner's general licences under the Wildlife and Countryside Act 1981 which permitted the control of pest species, the court rejected contentions that the decisions were ultra vires; that there was a failure to follow the rationale of the respondent's policy and to consider the petitioner's management systems; that the decisions were illogical and disproportionate in their impact; that the reasons stated were inadequate; that there was a breach of natural justice, and that there was a failure to meet the petitioner's legitimate expectations.
