I do not accept that this result was within the contemplation of the parties to the Convention on which Mr. Dudney seeks to rely. No doubt there are providers of independent personal services who, because of the nature of their skill or the services they provide, require very little in the way of a fixed place of business. Mr. Dudney may be one of those people. However, recognition of that fact does not justify the conclusion that Mr. Dudney must necessarily have a fixed place of business wherever his services are provided. The analogy suggested by counsel for Mr. Dudney is an apt one. A Canadian lawyer does not acquire a fixed place of business in the office of a client in the United States merely by attending to the client"s affairs there, even if the client insists on the lawyer"s personal presence.
