I had understood Mr. Wilson to be referring to subsection 5(4) of the present Citizenship Act, and my answer was that I was not aware of whether or not Mr. Chapman had made a submission to the minister on that matter.
I can't comment on whether or not Mr. Chapman did make a claim to get his citizenship back under the previous Citizenship Act, the 1947 act, during that period from 1947 to 1977, because frankly I don't know the answer to the question.
