Biddle and Child Support Registrar (Child support)

The Administrative Appeals Tribunal (AAT) considered the dispute between Biddle and the Child Support Registrar concerning a decision to revoke and make a new determination of the percentage of care.

The primary legal issue before the Tribunal was whether there had been a change in the likely pattern of care that warranted the revocation of the existing percentage of care determination and the making of a new one.

The Tribunal found that the evidence presented demonstrated a significant and ongoing change in the likely pattern of care. Applying the principles of the *Child Support (Registration and Collection) Act 1988*, the Tribunal determined that the existing assessment no longer accurately reflected the reality of the care arrangements. Consequently, the Tribunal set aside the original decision and substituted it with a new determination reflecting the altered care arrangements.
