Have you got to the point where you can give advice (in a litigation context) without worrying that maybe your research of the law missed a key legal provision, or that your assessment of the evidence was reasonable?
In routine cases where there's no law, I don't worry that much anymore, although I do go back and forward on making judgments about what to do. But if the law is unfamiliar, then I'm always thinking 'Did I find all the relevant legal provisions' (which might be across several different Acts including now repealed legislation) and key cases.
Does this ever go away? I'm 5 years into a brand new area of law but in my late thirties.
Please don't be to mean!
