Who is A.D. Neale from Capitalism, the Unknown Ideal and what is their importance?

Neale is a British author who wrote The Antitrust Laws of the United States. The author is a British civil servant and a liberal. His basic premise is that restriction of free trade is the basis of antitrust laws. He claims the laws are written in such a way nobody can figure out what they mean without studying all of case law to see what meanings there are. There is no way to determine a priori if an action is illegal. There is no way to give any broad interpretation to any statute.
