Twigg and Semcken (Child support)

The matter of *Twigg and Semcken* concerned a dispute regarding the percentage of care arrangements for a child. The applicant sought to have existing percentage of care determinations revoked and new determinations made, alleging a change to the likely pattern of care. The court was required to consider whether the circumstances warranted such a revocation and the making of new determinations.

The central legal issue before the court was whether there had been a material change in the likely pattern of care for the child, such that the existing percentage of care determinations were no longer accurate or appropriate. This involved an assessment of the factual circumstances and their impact on the established care arrangements. The court also had to consider the implications of non-compliance with previous court orders and the application of interim provisions during the period of dispute.

In reaching its decision, the court applied the principles governing the assessment of percentage of care under the relevant legislation. It considered evidence presented regarding the actual care arrangements and the intentions of the parties. The court affirmed the decision under review, indicating that it found no sufficient grounds to revoke the existing determinations or to make new ones based on the evidence presented. The court's reasoning focused on the established legal tests for determining a change in the likely pattern of care and the evidence presented by the parties in relation to those tests.
