Firstly we are discussing the legality not the ethical position
Are we? I'll have to review the thread, but I wasn't aware of anybody questioning the legality of what the Scottish government is doing, only whether it is
right. Let me just check....
... Yep. I don't see anybody questioning the law. You first brought up the law in response to NS saying
I presume you mean 'made aware of and show that they understand'?
But also consent is a process, it is not a one off event. So were a professional to become aware that a person might have misheard or misinterpreted a point then they would be well advised to ensure that the consent remained valid.
Is this the law still, or just your opinion? If it's the law, then I think it justifies NS's comment (quoted above) unless you are going to nit pick the distinction between "not showing they don't understand" and "showing they do understand".
But that isn't what we are talking about - we are discussing whether actual understanding is a requirement for capacity to consent - it isn't.
Yes, but you also said this
But if you have the ability to understand the information, can retain the information, believe the information and can arrive at a choice then you will be considered to have capacity to consent.
It would be hard to argue that a person has not understood the information if all of those conditions must apply.
And it isn't for both obvious, and less obvious reasons. The obvious is that the medical profession would have to test actual understanding, which would potentially be impossible or unethical, in order to determine whether treatment was valid under consent. But there is another point - consent is about arriving at a decision, nor about whether that decision is deemed by others to be rational or sensible. So the reasonableness of the decision in the eyes of others has no bearing on whether that decision is consensual.
So a person may refuse to engage with the information and make a decision that others may feel is completely unreasonable or irrational - that wouldn't mean that they did not have capacity to consent nor that their consent wasn't valid.
Refusing to engage is not the same as failing to understand.
You are arguing fine points of legality in a discussion about right and wrong. That's just not a convincing argument.
And as for "testing understanding" I am pretty sure a good doctor would do that, informally. I have been fortunate not to be in the situation, but I would hope that, if I was about to give consent for a risky procedure the doctor would explain the risks and ask if I understood. If my responses indicate in any way that I didn't understand, I would hope they would try to rectify the situation.
Anyway, as I said. This isn't about what is legal. You are the only one bringing up the law. This is about what is right or wrong.
