At first I thought it involved talking about Hart-Dworkin debate on separability between law and morals - is this correct?
For example, Nazi laws (as discussed by Hart, Shapiro etc)
But what else can I discuss that is relevant to this question?
Perhaps, Hart's rule of recognition?
And legal obligation?
Also, would Fuller's 8 principles of legality in the 'Internal Morality of law' be relevant here - for the 'good law' part?
Overall, I'm not sure of the argument to shape my essay through evaluation of the statement. Is it too simplistic of a statement to say that understanding law and not understanding what good law is to be separate??
I'd appreciate any help or suggestions anyone has
