Adam Brooks is no longer fighting firearms charges locally, after Tasmania Police announced there was no reasonable prospect of a conviction.
In a statement released yesterday, police said "the person in question has been formally notified of the outcome. There will be no further police action in relation to this matter."
That hasn't stopped similar counts, as well as a fake ID allegation proceeding in Queensland, where the former Mining Minister faced court again on Wednesday.
Mr Brooks hasn't entered pleas on any of the charges and the matter has been adjourned until next month.
He's been in Queensland since resigning on the same day he was announced a winner of the northwest seat of Braddon.
It came after the interstate firearms charges emerged, as well as scandalous reports he dated women under a false identity.
The issue has been front and centre during Question Time in State Parliament, and Labor Leader David O'Byrne says it isn't going to go away.
"It's no longer about Mr Brooks, he deserves procedural fairness and he does deserve to have his time in court," he said.
"But this is about Mr Gutwein and the decisions he chose to seek power in this parliament."
Greens Leader Cassy O'Connor says the Liberals have plenty of explaining to do about why they allowed Mr Brooks to run in the first place.
"Yes this matter should be examined," she said.
"Preferably it would be examined by both houses of the Tasmanian Parliament."
