MONTREAL - The author of a new book that alleges some the Supreme Court of Canada justices intervened in the patriation of the Constitution says he has questions about the internal review into the matter.
Frederic Bastien says he wants to know more details about how the Supreme Court conducted its investigation.
He also wants to know why the Canadian government continues to keep some documents from the period secret.
The court launched the review after Bastien's book, "La bataille de Londres," set off a political controversy in Quebec.
In the book, Bastien says that Canada's then chief justice of the Supreme Court provided information to the Canadian and British governments on discussions between the justices about the legality of repatriation.
Bastien suggests that would be a violation of the principle of separation of executive and judicial powers.
Canada's highest court announced on Friday that it had completed a review of its own records and found nothing related to the allegations.
Bastien based his account on British government documents he got under the United Kingdom's freedom-of-information laws.
But Bastien says part of the story is still missing, because the Canadian government hasn't handed over requested documents and has only provided heavily redacted pages.
"If a period of 30 years is not enough for us to make documents public, I would like to know if it will take 30 years, a period of 50 years, or if it will take 200 years," Bastien said Sunday.
NDP Leader Tom Mulcair, whose party holds a majority of seats in Quebec has already called the Supreme Court's investigation and findings into question. The Quebec government also wants a more thorough review.
