Marilyn McMahon joined the School of Law in February 2012, having previously worked at La Trobe University. Her research interests are in the areas of criminal law, criminal procedure, criminal responsibility and evidence. She is currently involved in three major research projects. The first is an investigation of the rule against double jeopardy and it contemporary reform in Australia. The second project explores self-defence, comparing developments in the United States with those in Australia. The final project is an historical exploration of how women who are victims of domstic violence are constructed in legal proceedings, especially where they have killed their abusive partner.
Marilyn has published articles on criminal defences (self-defence and mental state defences) and criminal procedure. She currently is supervising graduate students who are exploring the criminalisation of the infliction of mental harm and the reform of bail in Victoria. She is happy to supervise research students in any aspect of criminal law, criminal procedure and criminal justice.
