The Court of Appeal clarified in Manjit Singh s/o Kirpal Singh v. Attorney-General (2013). that if the power exercised by a body has a legislative source, this will "ordinarily mean that it is amenable to judicial review in the absence of compelling reasons to the contrary".Manjit Singh, para. 28. However, this is not an invariable rule, and there are situations in which a statutory power is not amenable to judicial review. Examples of these include the powers and duties conferred or imposed on corporations by the Companies Act,. and on trustees by the Trustees Act..Manjit Singh, paras. 30–31. The Court cited with approval the following passage from R. (Beer (trading as Hammer Trout Farm)) v. Hampshire Farmers' Markets Ltd. (2003):.Manjit Singh, para. 32.
