That's true. It's not possible. On that subject, see the Federal Court of Appeal's decision in Bourbonnais v. Canada in your documents. The reference is “Bourbonnais v. Canada (A.G.), 2006 FCA 62”. Writing for the court, Judge Nadon held that judicial independence provided the judge with a right to a lawyer paid by the government for the purposes of the disciplinary process.
It isn't at all clear from that decision that legal cost indemnification would ultimately be compatible with judicial independence. There's no clear answer to that question.
