Of seeing to fair play.
I wish I could feel as strongly as Sir Patrick Hastings (the late King’s Counsel) felt for his judiciary:
“…Lord Reading was by far the best Lord Chief Justice I have ever known. True, he had every possible advantage. A magnificent appearance and a beautiful voice were perhaps the least of his judicial attributes. His real claim to recognition during the period of his office as head of the King’s Bench Division lay in his inflexible determination that no litigant should leave his court dissatisfied with the conduct of his trial. No one has ever left Lord Reading’s Court who could raise one word of complaint against the presiding judge. His courtesy, his strict impartiality, above all his obvious determination that fair play as English men and women understand it should be maintained from beginning to end left an undoubted mark upon the Courts during period of office…”
