Langdon and Child Support Registrar (Child support)

This matter concerned an appeal by Langdon against a decision of the Child Support Registrar regarding the percentage of care for a child. The dispute centred on the Registrar's determination of the likely pattern of care, which forms the basis for calculating child support obligations. The appeal was heard by Justice Cuthbert of the Federal Circuit and Family Court of Australia.

The primary legal issue before the court was whether the Registrar's decision regarding the likely pattern of care was based on sufficient evidence and correctly applied the relevant legislative provisions. Specifically, the court had to consider the evidence presented by Langdon concerning the actual care arrangements and whether these arrangements supported the Registrar's conclusion about the future pattern of care.

Justice Cuthbert found that the Registrar had erred in its assessment of the likely pattern of care. The court reasoned that the Registrar's decision did not adequately consider the evidence of the actual care provided by Langdon, which demonstrated a significantly higher percentage of care than that determined by the Registrar. The court applied the principles of administrative law, requiring decisions to be supported by evidence and to be reasonable, and found that the Registrar's determination was not supported by the evidence before it.

Consequently, the court set aside the Registrar's decision and substituted its own finding regarding the percentage of care.
