Mr. Speaker, the hon. gentleman's question indicates clearly, unequivocally and beyond all doubt that what he is referring to is a matter that is in fact sub judice. The rules that are pronounced by the table and the rules as articulated in the House by Mr. Van Loan are very clear. Whether the opposition wishes to persist in the line of questioning or not, that line of questioning is inappropriate and ministers are prevented from responding to those questions for fear of prejudicing the matter before the courts.
In the House of Commons on October 19th, 2018. See this statement in context.
