You probably remember that earlier this year, Norfolk County Council achieved the dubious distinction of being the first local authority to be challenged legally over "systemic failings" in their duties under the Care Act 2014. Equal Lives referred them to the Care Quality Commission (CQC) for investigation.
If you thought, as I did, that this would result in the Commission probing their adult social care activities, you would be wrong. It is for the Secretary of State, Jeremy Hunt, to authorise an investigation, and he hasn't done so. You can read more of the saga, and what sort of inspection the council will be subjected to, here.
If you have an issue with a local authority, there is an easier way of raising your concerns, which is little talked about. Every council has a Monitoring Officer whose brief is to look out for incidents of alleged unlawfulness within the council. They should be your first port of call if you believe that the LA has acted unlawfully. You can read more about their statutory duties here, as well as accessing a contact list put together by Belinda Schwehr, leading expert in adult social care law.
