I'm still a senator: Rod Culleton

Rod Culleton insists he is still a senator, arguing the president of the Senate has jumped the gun in removing him.

The former One Nation senator is in Canberra on Tuesday seeking to have the High Court - sitting as the Court of Disputed Returns - take into account his legal challenge to a bankruptcy declaration.

"No one is above the law," he told AAP outside court.

He argues Senate President Stephen Parry had no legal right to remove him as a senator and that he and Attorney-General George Brandis have been summonsed to appear.

"He's not my superior - just because he's nominated to sit as the president in the Senate doesn't give him powers above the law.

"Who are they to disadvantage the people of Western Australia?"

"They have no right to do that."

Mr Culleton is awaiting a High Court decision on whether he was eligible to run for parliament in 2016 due to an existing larceny conviction.

In the meantime, he's been stripped of his West Australian Senate seat after the Federal Court declared him bankrupt on December 23.

Mr Culleton is arguing his removal as a senator has been premature, because he is challenging his bankruptcy.

After the court hearing, he intends going to his Parliament House office - which his chief of staff had to pack up on the Australia Day public holiday last week.

The nameplate outside Mr Culleton's parliamentary office has already been removed.

The finance department has also issued him a notice to move out of his Perth office and hand back equipment such as phones and computers.

He refused to say how his travel across the country for court hearings was being funded, saying it was not the business of taxpayers or media.

His chief of staff also became upset with reporters repeatedly calling her boss "Mister" Culleton, insisting the proper honorific was to still "senator".

Justice Stephen Gageler will hear Mr Culleton's summons on Tuesday morning.
