Judicial Registrar Tran wrote:Conclusion
68 Michael has, it seems, not paid tax for over 9 years. He has provided extensive written and oral submissions to the Court arguing that notwithstanding this, the DCT [Deputy Commissioner of Taxation - Gravy] has no power to sue him for unpaid tax and that this Court has no power to determine the DCT’s claims. In the course of those submissions he has relied upon, among other things, a number of cases relating to constitutional principles applicable in the United States of America. In the end, I have determined that none of his jurisdictional objections can be sustained.
69 I conclude these reasons with a quotation of my own from Benjamin Franklin, a contributor to the drafting of the American constitution and one of America’s Founding Fathers: 
“Our new Constitution is now established, and has an appearance that promises permanency; but in this world nothing can be said to be certain, except death and taxes.”
He's a lunatic.
