Kline v Official Secretary to the Governor General and Anor

The applicants, Mr. and Mrs. Kline, sought judicial review of a decision by the Official Secretary to the Governor-General, acting on behalf of the Governor-General, to refuse their application for a grant of citizenship. The applicants, who were citizens of the United States, had applied for Australian citizenship under section 21(2)(c) of the *Australian Citizenship Act 1948* (Cth) (the Act), which required them to demonstrate that they had resided in Australia for a period of four years immediately preceding the date of their application, including at least twelve months as a permanent resident. The applicants had resided in Australia for the requisite period, but their applications were refused on the basis that they had not been permanent residents for the full twelve months immediately preceding the date of their application. The matter came before the High Court of Australia.

The central legal issue before the High Court was the proper interpretation of section 21(2)(c) of the *Australian Citizenship Act 1948* (Cth), specifically whether the requirement for twelve months of permanent residency could be satisfied by a period that concluded *before* the four-year period of general residency. The applicants contended that the twelve-month permanent residency requirement did not need to immediately precede the date of application, but rather could fall within the broader four-year residency period. The respondents argued that the wording of the section mandated that the twelve months of permanent residency must immediately precede the date of application.

The High Court, by majority, held that the phrase "immediately preceding the date of their application" in section 21(2)(c) applied to the entire period of four years of residence, and therefore the twelve months of permanent residency must also immediately precede the date of application. The Court reasoned that the structure of the subsection indicated a single, continuous period of residence, part of which must be as a permanent resident. To interpret it otherwise would be to read the words "immediately preceding the date of their application" as modifying only the immediately preceding phrase "permanent resident," which the Court found to be an unnatural reading of the statutory language. The Court therefore dismissed the applicants' application.
