# Reference question

In Canadian law, a reference question or reference case (formally called abstract review) is a submission by the federal or a provincial government to the courts asking for an advisory opinion on a major legal issue. Typically the question concerns the constitutionality of legislation.

## Constitutional and statutory authority
### Reference jurisdiction of the Supreme Court of Canada

The Constitution Act, 1867, gives the federal Parliament the power to create a "General Court of Appeal for Canada", but does not define the jurisdiction of the Court. When Parliament created the Supreme Court of Canada in 1875, it gave the federal Cabinet the power to refer questions to the Supreme Court for the Court's opinion. That provision has been carried forward and is now found in the current Supreme Court Act.
Under that provision, the federal Cabinet may submit a question to the Supreme Court of Canada by means of an order-in-council. Once the questions have been submitted to the Court, the Court has complete control over the process to be followed. The reference is treated in the same way as an appeal. The Attorney General of Canada is entitled to appear before the Court and to make submissions. The Attorneys General of the provinces and territories are entitled to notice of a reference and may appear on it. Interested parties are able to apply for intervener status to make submissions during the hearing. When necessary, the Court may appoint an amicus curiae to submit a factum to support a particular view.
Once the parties have been determined, the Court sets out a timetable for the filing of written submissions, and for the date of the hearing. Parties to the reference file detailed written submissions on the legal issues raised by the reference, supplemented by factual records if necessary. After all written submissions have been filed, the Court holds an oral hearing on the reference questions. At the conclusion of the hearing, the Court typically reserves its decision. At a later date, the Court releases its opinion on the reference, in the form of a detailed written judgment. Individual judges of the Court are entitled to dissent from the majority opinion, in the same way as with judgments in appeals.
The opinion given by the Supreme Court is in the form of a judicial decision but is not legally binding; nevertheless, no government has ever ignored the opinion.
Prior to 1949, there was an appeal from the Supreme Court to the Judicial Committee of the Privy Council of the United Kingdom, sitting in London. The Judicial Committee served as the highest court for the British Empire and Commonwealth. Many federal reference questions were appealed to the Judicial Committee, which had the final say and could overrule the decision of the Supreme Court.

### Reference jurisdiction of the provincial courts

The provincial governments, under their respective Constitutional Questions Acts, are able to submit questions to the provincial Superior Court or Court of Appeal. The process is very similar to the federal government reference questions. Once the provincial Court of Appeal has given its decision on the reference question, the government or other parties to the reference have the right under the Supreme Court Act to appeal the decision to the Supreme Court of Canada.
Prior to 1949, appeals lay directly from the provincial courts of appeal to the Judicial Committee of the Privy Council. This right of direct appeal allowed litigants to by-pass the Supreme Court, so many provincial reference cases were never heard by the Supreme Court. The Supreme Court was then required to follow the decision of the Judicial Committee.

## Constitutionality of the reference jurisdiction

There have been challenges to the power of the federal government to confer the reference jurisdiction on the Supreme Court, but these challenges have been rejected, most recently in the Reference re Secession of Quebec in 1998.
Pursuant to the ruling of the Judicial Committee of the Privy Council in Attorney-General of Ontario v. Attorney-General of Canada (References Reference) [1912] A.C. 571, the role of the courts in references is not judicial as such, but one of advising the executive branch of government.

## Federal reference questions

There have been over 75 federal references to the Supreme Court since 1892. Prior to the abolition of appeals to the Judicial Committee, many of the earlier federal references went on appeal from the Supreme Court to the Judicial Committee. Since the abolition of appeals, the Supreme Court decision is the final say on a federal reference.

## Provincial reference questions

The provincial governments have the power to refer legal issues to their courts as well. Prior to the abolition of appeals to the Judicial Committee, those reference questions could be appealed directly to the Judicial Committee, by-passing the Supreme Court. Since the abolition of appeals to the Judicial Committee, there is a right of appeal from the provincial courts to the Supreme Court on a provincial reference.

## Reference jurisdiction in other countries

The government of the United Kingdom has the power to refer questions to the Judicial Committee of the Privy Council. This power served as one of the inspirations for the reference power under the Supreme Court Act. There has been one reference directly under this power to the Judicial Committee which related to Canada, concerning the Labrador boundary dispute between Canada and Newfoundland, which at that time was an independent dominion, not part of Canada. Other Commonwealth countries, such as India, South Africa, and Papua New Guinea also have implemented a reference jurisdiction in their constitutions. In the case of Papua New Guinea, their constitutional convention immediately prior to independence took counsel from Canadian legal academics on the use of the reference jurisdiction.
Other jurisdictions, notably Australia and the United States, eschew reference jurisdiction for their courts. In the United States, the case or controversy clause of Article III of the United States Constitution limits federal courts to hear only actual cases; advisory opinions are not permitted at the federal level (although some state constitutions do provide for such opinions). Likewise, the Australian Constitution has a similar requirement in Chapter III of the Constitution.
