Evidence being compiled and talks to be had for Matthew John Riley, accused of New England Highway rampage before Willow Tree arrest

Matthew John Riley has remained behind bars since his dramatic highway arrest at a Willow Tree truck stop south of Tamworth on the afternoon of July 13.

He did not appear in Tamworth Local Court on Wednesday.

Defence solicitor Garry Johnston said there were two matters listed - one with the police prosecutors and one which had been handed over to the state prosecuting authority, the DPP.

He said there was a problem with the charges laid out in the two matters.

"They are duplicitous," he told the court.

He said he had spoken to the Tamworth detective in the case and that some charges could be withdrawn because they are covered by other more serious ones that were levelled.

"I'm happy to make representations to the detective to perhaps have some conversations with his colleague and see if we can't have the matters resolve," Mr Johnston said.

Magistrate Lisa Stapleton agreed to adjourn Riley's matters for those discussions.

In the more serious case that the DPP is already involved in, the court heard more time was needed for the brief of evidence to be compiled and served.

"I just don't want to create mentions that can't be productive," Ms Stapleton said, setting the matters down for November.

Riley made no bid for bail and his release was formally denied.
