In 2017 the Royal Commission’s final report recommended its use throughout Australia.
Penny created and researches ‘the ground rules approach’ for witness evidence. Her innovative research and teaching has led to changes in court practice including the introduction of Criminal Procedure Rule 3.9(7) on ground rules.
