Yup, that was the case I mentioned earlier, when it is a case of someone not making the decision for themselves, but making it for other people then, yes, there needs to be guidelines and limits, I'll accept that as given, but also it is important to not assume that every decision made by the courts in these matters is 'right' purely because it matches up to what we think the decision ought to have been in the first place.
Parents make the 'wrong' decisions for their children at times, it could be anything from leaving them in a car while they shop, to ignoring them when they complain about being bullied at school, fortunately, there is pretty strong defence against the Government getting too carried away with telling parents what are the correct decisions to make, but those defences will remain strong only so long as people allow them to.
