Professional advice in England is confined to legal advice. - George Jessel

Mistakes are the inevitable lot of mankind.

I never did approve, when at the Bar, and I do not approve now, when on the Bench, of the practice of not deciding a substantial question when it is fairly raised between the parties and argued, simply because it is raised by demurrer. It is a great benefit to all parties to have the question in the case speedily and cheaply determined, and the practice of demurring ought, if possible, to be encouraged.

I may be wrong, and often am, but I never doubt.
