R v N&E Devon Health Authority, ex parte Coughlan [2000]

Coughlan,
patient at NHS facility, had received assurance she could live there as long as
she chose.
Health
authority then decided to transfer her.
Coughlan
applied for JR of decision.
Court
of Appeal held that assurance had induced legitimate expectation of substantive
benefit whose frustration would be so unfair as to amount to abuse of power.
