R (on the application of G) v Governors of X School and another (Secretary of State for Children, Schools and Families and another intervening) [2010] EWCA Civ 1, [2010] All ER (D) 118 (Jan)
Where an individual was subject to two or more sets of proceedings, or two or more phases of a single proceeding, and a “civil right or obligation” enjoyed or owed by him would be determined in one of them, he might, by force of Art 6 of the European Convention on Human Rights, enjoy appropriate procedural rights in relation to any of the others if the outcome of that other would have a substantial influence or effect on the determination of the civil right or obligation. The influence or effect had to play a major part in the civil right’s determination.
