This liberalising trend has also been reflected in the approach to individuals who seek to challenge administrative decisions, not so much because their own interests are directly impacted but because of their concern, as a citizen, about a particular public issue. For example, in R v Secretary of State for Foreign and Commonwealth Affairs, ex parte Rees- Mogg [1995] 1 W.L.R. 386, a former editor of The Times newspaper, who had frequently written about EU membership, was held to have standing to challenge the signing of the Treaty of European Union ('the Maastricht Treaty') because of his 'sincere concern for constitutional issues'.
