This week the High Court  handed down a landmark judgement affirming that a sperm donor can be classified as a child’s legal parent in certain circumstances. The biological parents of the child in question had been friends for decades when they decided to conceive a child, agreeing that the biological father would be involved in the daughter’s life on a regular basis. The biological mother re-partnered and had another child, and wanted to re-locate with the family to New Zealand. However, the High Court has found in favour of the biological father, ordering that the family remain in Australia. We were joined by Cassandra Seery from Deakin University’s Law School to discuss the implications of this finding for family law in Australia.
