Federal Court challenge to Adelaide MotoGP circuit falls over

A Queensland man's Federal Court challenge against the South Australian government's MotoGP circuit has been discontinued.

Joshua Hogan lodged action in the Federal Court in September seeking a permanent injunction against the proposed $96 million Adelaide circuit, which will require the removal of nearly 400 trees and is due to begin construction in December.

But at a brief hearing on Thursday morning, Judicial Registrar Michael Buckingham said the proceedings "were going to be discontinued".

Asked if any of the parties had anything to add, Mr Hogan said: "I'm fine, I just want to get this over my depression's pretty bad."

Judicial Registrar Buckingham replied that he understood and he "hoped this proceeding would come to an end for everyone's sake very quickly".

The state and federal governments are not seeking costs from Mr Hogan.
