Technically, this was not a lawsuit.

It was an enforcement action from the Workplace Relations Commission, and can be appealed in court.

I'm assuming because a lot of the time when it's clear that he's going to lose, he just pulls out of the case. Just like how he filed paperwork to get out of purchasing twitter but when it became clear that the ruling would be against him, he cancelled it says before it was about to be heard

Has he won any significant ones? He’s likely losing his pay package in court and had to buy twitter because his lawsuit wasn’t going anywhere.
