Disputed evidence, oppressive questioning and jury bungles are just some of the grounds for appeal Erin Patterson has outlined in her application to the Supreme Court of Victoria.

The convicted triple-murderer filed the application on the final day of the appeal period, claiming a substantial miscarriage of justice had occurred during her now infamous mushroom murders trial.

In this episode, ABC court reporter Kristian Silva joins Stephen Stockwell to talk through the appeal grounds, explain how they're assessed and return to the lingering question of motive.
