David Gibson's dumping from Queensland Premier Campbell Newman's first cabinet came just 13 days after he was appointed as Police and Community Safety Minister, amid a planned investigation into claims he was caught speeding while driving unlicensed.
Here's how it all came to a head:
May 2011: Gympie MP David Gibson – then an opposition frontbencher – receives a speeding fine which he later says he simply forgot to pay.
Subsequent months: The matter is referred to the State Penalties Enforcement Registry, which chases up unpaid fines. Up to five letters are said to have been sent out to Mr Gibson's home during this process. Mr Gibson says he did not see any notices informing him of an imminent or actual licence suspension.
November 18: David Gibson's licence suspension takes force as a result of the failure to pay the fine.
February 16, 2012: A hire car is snapped speeding on the Bruce Highway. It is the final sitting day of Parliament before the election. Mr Gibson is later identified as the alleged driver of the vehicle at the time.
February 18: Mr Gibson's three-month licence suspension is due to expire.
March 24: The Liberal National Party storms into power with a crushing election victory over the Bligh Government, which has previously faced criticism over a failure to enforce ministerial accountability.
April 3: David Gibson is sworn in as Police and Community Safety Minister during a ceremony at Government House, Paddington.
April 5: Commissioner Bob Atkinson meets with Mr Gibson to tell him a “normal” cabinet-related security check suggests he has an unpaid fine that could trigger a licence suspension.
April 15: After subsequent checks reveal that the suspension has already occurred and that Mr Gibson was allegedly the driver of the speeding car on February 16, Mr Atkinson meets with the Minister again to tell him he now faces an investigation into unlicensed driving, with police officers required to formally interview Mr Gibson on the matter in the near future.
April 16: Mr Gibson meets with Campbell Newman to talk about the matter and offers his resignation after being told his cabinet position is no longer tenable.
April 17: Bundaberg MP Jack Dempsey is named as the new police minister. Mr Gibson says he failed to pay the speeding fine last year because he is human but insists he did not see any correspondence suggesting his licence was to be suspended.
