In the letter, dated January 4, 2017, Culleton asked Senate president Stephen Parry to "invoke Standing Order 58 (b) and (c ) as a matter of urgency" and recall Parliament, to allow the Senate to decide "as a priority" whether the ruling is valid.

Culleton wants the Senate to be allowed to vote on overruling the Federal Court, which declared him bankrupt in December as the result of legal action taken by former Wesfarmers director Dick Lester, who is seeking $280,000 from Culleton.

The Australian Constitution prevents anyone who is bankrupt from running for, or sitting in, federal parliament.

But if the Senate votes to overturn his bankruptcy ruling, Culleton would be allowed to continue serving as a senator for Western Australia.

"The Senate needs to make the Federal Court of Australia competitive with the State Courts, instead of being blindingly accepting of their unconstitutional judgements," he wrote.
