[2006] EWHC 1083 (Admin), 17 May 2006. Considers whether the construction of the term appropriate person in relation to the Environmental Protection Act 1990 Part IIA should include both the original polluter and its statutory successors. Application by T for judicial review of a decision of E that T was an appropriate person within Part IIA of the Act in respect of contaminated land. E had decided that T was an appropriate person to pay for remedial work for the purposes of the Act on the ground that the pollution had been caused by one or more of T's statutory predecessors that had operated at the site. T contended that the decision was wrong in law because T had not itself knowingly caused or permitted the contamination and was therefore outside the ambit of s78 of the Act and had no existing liability under the Gas Acts 1972 and 1986. "Held": Part IIA of the 1990 Act clearly intends that primary responsibility for the remediation of contaminated land should rest on the original polluter but the only way this intention could be implemented is to construe the term appropriate person to include both the original polluter and its statutory successors
