around whether she was truly a resident of Saskatchewan, although she does own property in the province. In 2013, however, a Senate committee launched a review, ordering all senators to provide documentation confirming their residency status following allegations of irregularities in some senators' housing expense claims, including those of Wallin, Patrick Brazeau, Mac Harb and Mike Duffy. All provinces and territories have a similar requirement by which a person must be a resident of that province or territory to be eligible for election to the provincial or territorial legislative assembly. Depending on the province or territory, however, there may or may not be a legal requirement to be a resident of the specific district where one is standing as a candidate. United States As a general principle, in the United States residency for federal politicians is defined as the intent to return to the particular district or state they represent following their term in office. For example, the purchase or occupancy of a home in the DC metro area, for proximity to the Capitol and the Congressional offices, does not change an Iowa congressman's or congresswoman's legal residency in his or her state. Conversely, to be eligible for election to a state-level office, such as a state assembly or a governorship, a person must be resident within the state where they are running for office; however, states vary in whether or not an assembly candidate is required to reside in the specific district where they are running. In one noted recent case, Nevada Assembly candidate Andrew Martin's eligibility for office was called into question due to ambiguity regarding his residency status. Martin owned two properties, a condominium in the district where he was running for office and a house in a neighboring district, and his campaign was affected by conflicting claims about which property should be regarded as his primary residence. A judge ruled Martin ineligible to run on November 5, 2012, just one day before the election — but as the decision came too late for Clark County officials to reprint the ballots, Martin's name remained on the ballot and he won the election. Martin was allowed to take his seat in the legislature without a formal challenge being filed against him.
