· Important international case law such as the High Court of Australia’s decision in Commissioner of State Revenue v Rojoda Pty Ltd [2020] HCA 7, on the nature of a partner’s interest in a partnership.

· Contemporary litigation trends, including the application of proprietary estoppel principles in a partnership context in cases such as Guest v Guest [2022] UKSC 27.
