the scope of the clause has been limited by the jurisprudence of the Judicial Committee of the Privy Council (JCPC). The JCPC narrowed the scope of the clause to the three distinct branches which remain while also broadly interpreting the scope of provincial authority over property and civil rights under section 92(13) of the Constitution Act, 1867. The jurisprudence has been defined into three branches: Emergency Branch, Gap or Purely Residual Branch, and National Concern Branch, as defined in the Supreme Court of Canada judgment Re: Anti-Inflation Act. Interpretation doctrines Although the text of the Act gives Parliament residuary powers to enact laws in any area that has not been allocated to the provincial governments, subsequent jurisprudence has limited the scope of the "peace, order, and good government" power. The limitation on the scope of this clause stems from the narrow interpretation of its branches and the expansive interpretation of provincial powers under section 92 of the Constitution Act, 1867. Particularly limiting is the breadth of provincial power over property and civil rights under s. 92(13). Although the Emergency Branch and the National Concern Branch may be viewed as delimited federal competencies like the enumerated clauses under section 91 (see e.g. AG Canada v AG Ontario (Labour Conventions), [1937] AC 326 (PC)), the clause remains residuary. The powers under POGG must be interpreted in light of the subsequent jurisprudence on the limitations of the clause and the expansive powers of the provinces under their enumerated heads of power. If a matter does not fall within one of the enumerated classes in section 92, section 91, or the emergency or national concern branches, then it falls within the narrowly defined residual branch of POGG. The POGG power is best understood as a narrowly defined residual power limited to the following three branches. The Gap or Purely Residual Branch POGG's gap-filling power covers issues such as drafting oversights and matters not within the boundaries of a province. Drafting oversights include things the drafters of the Constitution forgot to think about but would unambiguously have allocated to Parliament if they had. For instance, section 92 allocates responsibility for provincially incorporated companies to the legislatures but section 91 says nothing about federally incorporated companies: the gap branch allocates this jurisdiction to Parliament, per John Deere Plow Co v Wharton, 1915. Matters not within the boundaries of a particular province include Canadian territorial lands and
