Stone and Lamalfa (Child support)

This matter concerned an appeal by Stone against a decision of the Child Support Registrar to refuse to revoke existing percentage of care determinations. Lamalfa was the other party to the proceedings.

The primary legal issue before the court was whether there had been a change to the likely pattern of care of the child, which would warrant the revocation of the existing percentage of care determinations.

The court affirmed the Registrar's decision, finding that the evidence did not establish a change to the likely pattern of care. The court applied the principles governing the assessment of changes to the pattern of care under the *Child Support (Registration and Collection) Act 1988*, concluding that the threshold for revoking the existing determinations had not been met.
