I can well believe she may need ongoing psychiatric care, she may need specific support for some decisions, or some areas of her life. But the golden rule (in the UK) when making any best interest decision, is that any proposed action MUST be the LEAST RESTRICTIVE option.
But this setup she is under seems to be the MOST restrictive.
It was never designed for this purpose, it was designed to allow protection for people with severe and permanent lack of capacity, for example an elderly person suffering with dementia, or someone with significant learning disability. Not for someone with a mental illness which may fluctuate and vary in severity.
She has the RIGHT to make poor choices. We all do. Making poor choices does NOT equal lack of mental capacity. And you can have capacity that fluctuates, depending on the time of day, month or decision to be made. And capacity decision are DECISION SPECIFIC, you can’t just blanket say someone ‘doesn’t have capacity’ - capacity for what?! Capacity to care for her children perhaps not, capacity to decide what to do with her day, who to see and what to eat, I can’t see any evidence that she doesn’t have capacity for that.
Like I said, I can well believe she requires some sort of support in some areas of her life, and the manager of that support may vary over the course of her life - but not this all encompassing permanent entrapment. It’s excessive and I can’t see ANY justification for it.
