> To take this to an extreme, are you saying that under UK law, it would be legal for Parliament to legalize slavery or permit other activities that would unconscionable and illegal without such action?

definitely. why is this surprising? countries permit all sorts of unconscionable things (the US had slavery and only banned it "except as a punishment for crime", literally has the death penalty right now) and by definition legislatures turn things from "illegal" to "legal" and vice versa constantly. the US could re-legalise slavery via a constitutional amendment any time it wanted, Ireland could ban divorce again, Australia could un-repeal Section 127, etc etc.

the only difference in the UK is that there's no "basic law" / "constitution" that's harder to change than regular laws.
