waters that are within provincial boundaries such as the seabed off the coast of Newfoundland, per Reference Re Seabed and Subsoil of Continental Shelf Offshore Newfoundland, [1984] 1 S.C.R. 86. The gap branch is rarely relied on because there is so little left to default to the federal government after taking into account the enumerated provincial power over property and civil rights under section 92(13) which applies to any transaction, person or activity that is found within the province. Historically new subject matters, such as aeronautics, do not necessarily fall residually to the federal government, per Johannesson v West St Paul (Rural Municipality of), 1952. The Emergency Branch Parliament may invoke emergency powers under the emergency branch of POGG. This began in 1882, when the Judicial Committee of the Privy Council (then the supreme authority over Canadian law) ruled in Russell v. The Queen that the federal government could legislate with regard to alcohol, because even though this would probably have been considered provincial jurisdiction in ordinary circumstances, the federal government was acting to ensure order in Canada. This concept further evolved during the 1920s, when in the 1922 Board of Commerce case, it was stated that POGG could be invoked in times of war and famine, to allow Parliament to intervene in matters of provincial jurisdiction. POGG was later used this way in the Anti-Inflation Reference of 1976, when the Supreme Court of Canada allowed Parliament to regulate inflation on the grounds that it posed a considerable economic problem for Canada. In that case, a great degree of deference was exercised in accepting what the federal government deemed to be an emergency. The National Concern Branch The "national concern" doctrine (sometimes referred to as "national dimensions") was an alternate means of applying the POGG powers that found use in the mid-20th century. It allowed Parliament to legislate on matters that would normally fall to the provincial government when the issue became of such importance that it concerned the entire country. The doctrine originated from a statement by Lord Watson in the Local Prohibition case (1896), wherein he stated: Their Lordships do not doubt that some matters, in their origin local and provincial, might attain such dimensions as to affect the body politic of the Dominion, and to justify the Canadian Parliament in passing laws for their regulation or abolition in the interest of the Dominion. After this case the
