Gerard Phillip Neskovcin, 34, is accused of assaulting a man by punching him to the head and kicking him to the body in September last year.

He is separately charged with disorderly conduct by allegedly abusing passers-by in Launceston's Cimitiere Street and then assaulting and resisting police.

Mr Neskovcin, who had fired his lawyer for not corresponding with him, entered a plea of demurrer in the Launceston Magistrates Court yesterday.

To enter a plea of demurrer is to take a stance that even if the allegations are true the complainant does not have grounds to pursue them.

Magistrate Tim Hill asked the defendant on what basis he was doing this.

Mr Neskovcin said the charges against him stemmed from admiralty law, which did not have jurisdiction.

He added that his surname on his birth certificate was written in capital letters.

"The argument you just put to me is a nonsense," Mr Hill said, refusing the application.

When the defendant refused to then enter pleas, Mr Hill said pleas of not guilty would be entered on his behalf.

This appeared to anger Mr Neskovcin, who said a magistrate was not able to act on his behalf and simultaneous sit in judgment of him.

"I'm a flesh and blood human being," he said.

Court staff then muted the audio-visual feed broadcasting Mr Neskovcin in the court room.

Mr Hill adjourned the mater to a later date.
