In a six to one jointly written decision (Moldaver, J. in dissent), the Supreme Court of Canada has answered the questions In the Matter of a Reference by the Governor in Council concerning sections 5 and 6 of the Supreme Court Act, R.S.C. 1985, c. S-26, as set out in Order in Council P.C. 2013-1105 dated October 22, 2013 2014 SCC 21 as follows:
1. Can a person who was, at any time, an advocate of at least 10 years standing at the Barreau du Québec be appointed to the Supreme Court of Canada as a member of the Supreme Court from Quebec pursuant to sections 5 and 6 of the Supreme Court Act?
“ In our view, the answer to this question is no: a current judge of the Federal Court of Appeal is not eligible for appointment under s. 6 as a person who may be appointed “from among the advocates of that Province”. This language requires that, at the time of appointment, the appointee be a current member of the Quebec bar with at least 10 years standing.
2. Can Parliament enact legislation that requires that a person be or has previously been a barrister or advocate of at least 10 years standing at the bar of a province as a condition of appointment as a judge of the Supreme Court of Canada or enact the annexed declaratory provisions as set out in clauses 471 and 472 of the Bill entitled Economic Action Plan 2013 Act, No. 2?
 On the question of whether Parliament can enact legislation purporting to declare a binding interpretation of s. 6 and thereby permit the appointment of a former member of the bar to one of the Quebec positions on the Court, our view is that the answer is also no. The eligibility requirements set out in s. 6 relate to the composition of the Court and are, therefore, constitutionally protected. Under s. 41(d) of theConstitution Act, 1982, any amendment in relation to the composition of the Supreme Court of Canada may only be made by proclamation issued by the Governor General under the Great Seal of Canada authorized by resolutions of the Senate and House of Commons and of the legislative assembly of each province.
The conclusion is that, in the words of the majority:
 The practical effect is that the appointment of Justice Nadon and his swearing-in as a judge of the Court were void ab initio. He remains a supernumerary judge of the Federal Court of Appeal.
