The talk was on protections that have been introduced in some jurisdictions providing for a second appeal to a court of criminal appeal (by leave) on proof of fresh and compelling evidence; and a new procedure adopted in England, Scotland, New Zealand, and Canada (but not yet in Australia) for a Criminal Cases Review Commission with interdisciplinary membership, to review claims of miscarriage of justice earlier rejected by the courts.  The speaker urges that each of these new remedies should be adopted in Australia.
