Freedoms. The rights specified include the right of citizens to leave and enter the country and the right of both citizens and permanent residents to move within its boundaries. However, the subsections protect poorer regions' affirmative action programs that favour residents who have lived in the region for longer. Section 6 mobility rights are among the select rights that cannot be limited by the Charter's notwithstanding clause. Canada's Social Union Framework Agreement, an agreement between governments made in 1999, affirms that "All governments believe that the freedom of movement of Canadians to pursue opportunities anywhere in Canada is an essential element of Canadian citizenship." In the Agreement, it is pledged that "Governments will ensure that no new barriers to mobility are created in new social policy initiatives." United States Freedom of movement under United States law is governed primarily by the Privileges and Immunities Clause of the United States Constitution which states, "The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States." As far back as the circuit court ruling in Corfield v. Coryell, 6 Fed. Cas. 546 (1823), freedom of movement has been judicially recognized as a fundamental Constitutional right. In Paul v.

Under the "privileges and immunities" clause, this authority was given to the states, a position the Court held consistently through the years in cases such as Ward v. Maryland, 79 U.S. 418 (1871), the Slaughter-House Cases, 83 U.S. 36 (1873) and United States v. Harris, 106 U.S. 629 (1883). Internationally, § 215 of the Immigration and Nationality Act of 1952 (currently codified at 8 U.S.C. § 1185), it is unlawful for a United States citizen to enter or exit the United States without a valid United States passport. Oceania Australia No federal Australian legislation guarantees freedom of movement within the Commonwealth of Australia. Various Australian laws restrict the right on various grounds. Until 1 July 2016, Norfolk Island had immigration controls separate from those of the remainder of Australia and a permit was required for Australian citizens or residents to enter. In August 2014 the Australian Commonwealth Government proposed regulating the rights of Australian citizens to
