The general principle on intervention in an adult’s affairs is that a person may intervene, or authorise an intervention, only if satisfied that the intervention—
(a)will provide benefit to the adult which could not reasonably be provided without intervening in the adult’s affairs, and
(b)is, of the range of options likely to fulfil the object of the intervention, the least restrictive to the adult’s freedom.
This section applies for the purposes of section 2 only.
