“I also understand that the department may use the information which it has now or may get in the future to decide whether I am entitled to the benefit I am claiming [as well as] any other benefit I may claim in the future.”
“… a decision should be regarded as having been made under section 10 [or section 9] regardless of the form in which it may be expressed if it has the effect of termination of an existing entitlement from the date of decision … the only possible inference is that the decision maker intended to supersede [or revise] under section 10 [or section 9]. There is no other power which enables the Secretary of State to change a previous decision as from the date of the new one and it would be ... wholly unrealistic to infer that the … decision, however inadequately expressed, was made … without any reference to section 10 [or section 9].”
“Although […] a person with a right of appeal against any decision [must] be given written notice of the decision, neither the Act [Social Security Act 1998 ] nor any regulation specifies any particular form in which decisions must be made – and a decision (as opposed to notification of a decision) is not even required to be made in writing.”
