The Act’s operative legal concepts are re-classification, validation, deeming as to lawfulness and effect, and the temporal fixing of entitlement and contribution obligations. Each concept is used in a tightly defined statutory manner.
Re-classification: The Act treats the listed variations in salary or salary limits as re-classifications of the named offices or positions. This is the terminology used in s 3(1), which declares that variations specified in the Schedule shall "be deemed to have been lawfully made and shall have effect... as a re-classification". The concept is functional: the statute converts previously made salary variations into formal re-classifications for legal purposes.
Deeming and validation: The primary legal technique is deeming. The Act does not create new substantive rights directly; rather it declares that prior administrative acts are to be regarded as lawfully made and effective from specific dates. Section 3(4) expressly deems actions taken before commencement by the listed authorities to be lawfully taken and effective from dates those authorities specified, if they did specify such dates. Section 3(1) and Schedule fix the dates of effect for the named re-classifications.
Non-vacancy: Section 3(2) contains an explicit deeming that an office or position re-classified under s 3(1) "shall be deemed not to have become vacant by reason of the re-classification". That is a discrete legal rule about incumbency status after a re-classification and alters the legal consequences that ordinarily attend to a vacancy.
Regulatory retroactivity: Section 3(3) contemplates and authorises the making of regulations under the Public Service Act 1922-1955 for purposes related to the re-classifications and further deems any such regulations to have commenced on 10 January 1956. The statute therefore extends its retrospective effect to associated regulatory instruments under the Public Service Act, not merely the primary administrative acts.
Validation of administrative determinations about salary within limits and increments: Section 3(5)(a)-(b) identifies that prior administrative action to set the rate of salary within newly varied limits and to determine the date of eligibility for the next increment is validated.
Superannuation deeming: Section 4 applies the same deeming technique to superannuation contribution obligations under the Superannuation Act 1922-1955. It identifies particular categories of employees and equipment of salary variation, and specifies that increased contributions payable under paragraph (a), (b) or (d) of subsection (4) of section 13 of that Superannuation Act are to be treated as having been payable from particular past dates. Different categories have different deemed start dates (s 4(a)-(b)).
Schedule as operational map: The Schedule is integral to the Act; it lists the specific offices and positions, the authority responsible, the date of the resolution and the date from which the resolution is to be treated as effective (Schedule, s 3 cross-reference). Examples include Commonwealth public service departments with resolutions by the Public Service Board on 10 January 1956, parliamentary departments with resolutions dated 9 March 1956 but with effect back to 10 January 1956, Overseas Telecommunications Commission positions with resolution on 3 February 1956 and effect on 18 February 1956, and Commonwealth Bank Service positions with resolution 25 January 1956 and effect 1 July 1955.
Temporal priority and heterogeneity: The Act creates a heterogeneous set of effective dates across the enumerated categories, and it distinguishes between the date of the authority’s resolution and the date from which its effect is deemed. The Schedule shows where the date of effect precedes the date of the resolution, which is central to the Act’s retrospective character.
Reference to other statutes and determinations: The Act operates in close relation to the Public Service Act 1922-1955, the Superannuation Act 1922-1955, Determinations made by the Public Service Arbitrator, and variations effected by the Commonwealth Court of Conciliation and Arbitration, as referenced in s 4. These cross-references determine the legal instruments whose consequences the Salaries Adjustment Act alters.
No penalty or enforcement apparatus: The Act contains no express enforcement or penalty provisions; its effects are declaratory and prospective in the sense of validating past acts and fixing dates for past payments and contributions. Any operational enforcement remains with the existing administrative and statutory frameworks referenced by the Act.
