I emailed the commission in January and they replied - this quoted paragraph says what is next:
"In case study 29, the Royal Commission will consider the submissions of Senior Counsel Assisting the Royal Commission and of the parties, and will publish its findings and recommendations in the Report of Case Study 29. At this time the Royal Commission is unable to provide a likely timeframe for the release of the Report."
I notice on their website they have reported findings in cases 1 through 20 and the report for case 1 was in March 2014 and the report for case 20 in November 2015.
They are slowly working their way through the cases.
Patience my friends ... the wheels grind slow but they grind very fine!
