Hoffman and Child Support Registrar (Child support)

This matter concerned an appeal to the Administrative Appeals Tribunal (the Tribunal) regarding decisions made by the Child Support Registrar (the Registrar) concerning the percentage of care arrangements for a child. The appellant, Hoffman, sought to have the Registrar's decisions revoked and new determinations made, while the Registrar's decisions were also under review by another party who argued that the existing percentage of care determinations should not have been revoked.

The Tribunal was required to determine whether there had been a change to the likely pattern of care for the child. This involved assessing whether the factual circumstances surrounding the child's living arrangements had altered sufficiently to warrant a revocation of existing percentage of care determinations and the making of new ones, or conversely, whether the existing determinations remained appropriate.

The Tribunal considered the evidence presented regarding the child's care arrangements. In one aspect of the case, the Tribunal found that there had been a change to the likely pattern of care, leading to the revocation of existing determinations and the making of new ones, affirming the Registrar's decision. However, in another aspect, the Tribunal concluded that no change to the likely pattern of care had occurred, and therefore, the existing percentage of care determinations should not have been revoked, setting aside the Registrar's decision and substituting it with its own.
