When we find a series of decisions running down from the time of Sir William Grant, we should be very cautious, and very slow to overrule them. - Nathaniel Lindley, Baron Lindley

It appears to me wrong in principle for any Court or Judge to impose fetters on the exercise by themselves or others of powers which are left by law to their discretion in each case as it arises.

I take it that reasonable human conduct is part of the ordinary course of things.

I do not mean to say that the Court could not give leave to amend, but I cannot conceive that the Court would listen to an application for leave to amend after the trial. That could not have been intended: it would be opposed to all principles of justice.
