Alev Giz appeared as junior counsel for the successful Appellant Father in the landmark case of re F (A Child) (International Relocation Cases) in which the Court of Appeal, further distancing itself from Payne v Payne, decided that a holistic, comparative, balance sheet approach is required in the evaluation of the competing proposals put forward by each parent and in the analysis of the child’s welfare in relocation cases, which must be subject to a proportionality cross check by virtue of the engagement of Article 8 rights and the risk of separation from the ‘left behind’ parent.
