Homelessness and fluctuating capacity

Apologies if this is not a clear question. Regarding assessment of capacity/decisions on accommodation and street homelessness. I am trying to find out if there have been any cases that have been adjudicated regarding fluctuating capacity and the refusal of help to move off the streets?

Hello, please see below links.

Thanks for really useful information.

If I want to look out for case law how do I search on the site ?

You can search via here Mental health case law - Mental Health Law Online

or try here Homeless Archives - Nearly Legal: Housing Law News and Comment and search for capacity
