Former WA One Nation senator Rod Culleton has been charged with allegedly giving false information to the Australian Electoral Commission.
Rod Culleton was charged after a federal police taskforce investigation, following a report from the AEC.
There were concerns that Mr Culleton had signed false declarations when nominating for the senate in this year's federal election, as a candidate for the Great Australia Party.
It's alleged he falsely declared his financial circumstances, for which the maximum penalty is 12 months in prison.
The constitution says someone who is bankrupt or insolvent can't sit in federal parliament.
In April, the AEC noted that Mr Culleton was listed as an 'undischarged bankrupt' on the National Personal Insolvency Index.
An arrest warrant for Mr Culleton was issued after he failed to appear in the Perth Magistrates Court on September 30.
Mr Culleton was elected as a One Nation Senator in 2016 but soon sat as an independent.
He was disqualified after he was declared bankrupt by the Federal Court and it was also found that he was ineligible due to a larceny conviction.
In a statement in April this year, in relation to the most recent concerns, the AEC said Mr Culleton's name would appear on the WA Senate ballot paper for the May election, but he would be ineligible to sit if elected.
'I've never been bankrupt': Culleton
Speaking from New South Wales, Mr Culleton questioned whether any arrest warrant was enforceable, but also said he would return to Western Australia when he was ready.
"I never avoid going to court," he said.
"As long as the court's in its proper jurisdiction. That is the first duty of any court — jurisdiction, jurisdiction, jurisdiction."
He said he did not give false information to the AEC.
"Not at all, why would I?" he said.
He said it was "absolutely nonsense" to say he was bankrupt, and declared he had not been bankrupt in the past.
"Nothing's changed, I have no trustee that handles my personal affairs, I'm very happy with my finances, I have representation in courts," he said.
"To be honest, I want it to go to trial, it needs to go to trial to put the end to this bastardising over this bullshit bankruptcy, because I'm not bankrupt, I've never been bankrupt.
Mr Culleton said if the AEC matter went to trial, he would seek to call his former party leader Pauline Hanson, as well as other serving and former MPs.
"Absolutely, I'll be calling the whole 45th parliament," he said.
"This is an absolute breach of law … I was duly elected, there is no question about that."
He asserted the Great Australian Party would field candidates in future elections.
