You need not cite cases that are familiar. - Sir Frederick Pollock, 1st Baronet

The rule is this: that wherever there is a decision of a Court of concurrent jurisdiction, the other Courts will adopt that as the basis of their decision, provided it can be appealed from. If it cannot be appealed from, then they will exercise their own judgment.

The Crown cannot ever be prejudiced by the misconduct or negligence of any of its officers.

You have no right, for the purpose of justifying a libel, to inquire into a man's life and opinions.
