Most Australians know about the Mabo and Wik decisions, but few know much about the decision makers — The High Court of Australia. Having gained historic access, THE HIGHEST COURT shows first hand the characters and drama of the High Court of Australia, the pinnacle of legal and constitutional processes in Australia. The role of the Court is explored as the film follows the handing down of two historic constitutional judgements, Kruger and Ha, and the appointment of two new Justices — Hayne and Callinan. For the first time cases have been filmed as they actually happen in the Court culminating with the recent Hindmarsh Island Bridge challenge.
