Why Lord David Neuberger chose "Pre-Raphaelite" to mean judges who read case's papers in advance?
Solution 1:
Anyone who has seen a painting by Raphael will know they have seen a view of the world that is grand and fine but very much better than the truth of the day. They are fabulous pictures but are a great deal nicer than any reality.
Naturally when Neuberger speaks of the Pre-Raphaelite he means those who look at the world as the Pre-Raphaelite did, meaning all together with its warts and blemishes including truths, both pretty and ugly. These people preferred their simple realism to the special effects version of reality painted up by Raphael.
As for considering a legal case Neuberger felt Pre-Raphaelites would do so by a complete and thorough reading of a case without sparing detail or turning away from any particulars, indelicate or otherwise. Preferring realism by way of thoroughness an completeness.
As he stated this was too much for his tastes. He preferred the Impressionist's approach who only considered the case in a shallow manner, sometimes by the lightest skimming. Taking in just enough of the matter before the reality becomes to tedious and relying on picking up the argument later during the discussion.
I don't have much of a stomach for the law but if I needed a lawyer I would hope it is a strong stomach for realism that I am hiring.
