Questione giuridica chiave
Whether the 2017 revision justified reducing the helplessness allowance from medium to light.
Decisione estratta
The alleged change in circumstances was not proven with the required probability; the claimant still met the requirements for a medium helplessness allowance.
Motivazione estratta
The court found continued substantial help in at least three daily life functions and continued need for personal supervision. The revision file and home assessment did not reliably show a material improvement justifying a reduction.
