St Clair; Secretary, Department of Social Services and

The matter before the court concerned an appeal by the Secretary of the Department of Social Services against a decision of the Social Security Appeals Tribunal (SSAT). The SSAT had set aside a decision by an Authorised Review Officer and found that the respondent, Mr St Clair, qualified for a Disability Support Pension (DSP). The dispute centred on whether Mr St Clair's medical conditions met the criteria for a DSP, specifically regarding the assessment of impairment ratings.

The legal issues before the court were whether the SSAT had correctly applied the Impairment Tables under the relevant legislation when assessing Mr St Clair's eligibility for a DSP. This involved determining if the SSAT erred in its approach to rating multiple impairments arising from distinct conditions, and whether a single global rating was appropriate or if individual impairments should be assessed against specific tables. The court was required to consider the legislative framework for selecting and applying the Impairment Tables, particularly sections 10(1) to 10(5) of the Rules.

The court reasoned that the SSAT had incorrectly applied the Impairment Tables by adopting a single global rating for Mr St Clair's combined impairments, as suggested by his representative. The court found that section 10 of the Rules mandates a specific process for table selection and assessment, requiring that impairments be rated under the table related to the function affected. Where a single condition causes multiple impairments, each impairment should be assessed under the relevant table, and where multiple conditions cause a common impairment, a single rating should be assigned under a single table. The court concluded that the SSAT's approach of using a single global rating on Table 1 for both a spinal condition and emphysema was contrary to these provisions.

Consequently, the court set aside the SSAT's decision. The court substituted a decision that Mr St Clair did not satisfy subsection 94(1)(b) of the Social Security Act 1991 during the relevant claim period and was therefore not qualified to receive the DSP.
