“The authors go on to say that there should not be a ‘judicial no-man’s land’; the principles to be applied in determining whether an entity is a ‘department of government’ should mirror those for determining whether the entity is a ‘separate entity’.”
“It is apparent from Lord Wilberforce’s statement of principle that the ultimate test of what constitutes an act jure imperii is whether the act in question is of its own character a governmental act, as opposed to an act which any private citizen can perform. It follows that, in the case of acts done by a separate entity, it is not enough that the entity should have acted on the directions of the state, because such an act need not possess the character of a governmental act.”
