The boy's special school told the council: "Many children at the special school had difficulties with challenging behaviour and sensory reactions which could make their behaviour unpredictable and cause distress.
The child, known as Child X, had previously received free school transport until age 8 due to his additional needs.
A West London council wrongly told parents their eight-year-old son with sensory and behavioural needs should walk three miles to school after refusing to provide transport.
Ealing Council applied "incorrect tests" when denying the child transport to and from school, the Local Government and Social Care Ombudsman has ruled.
Since the ombudsman's decision, we have held another stage 2 complaint appeal panel about this case, which found that the family met the necessary eligibility criteria due to the child's significant sensory difficulties.
