IT WILL be up to Premier Campbell Newman to decide when a by-election should be held, after LNP member for Stafford Dr Chris Davis' surprise resignation.
Dr Davis was sacked as Assistant Minister for Health last week.
Mr Newman said he was given no forewarning of the Stafford MP's decision to leave Parliament.
Dr Davis - a former Director of Geriatric Medicine at Brisbane's Prince Charles Hospital - was stripped of his ministerial position on May 15 after criticising the government's changes to doctor contracts and changes to the Crime and Misconduct Commission.
On Friday, the Brisbane member published a statement on his website.
"The passage of recent government legislation affecting critical aspects of our democracy goes contrary to my value system and that of the majority of my electorate," he said.
" I would never have stood for Parliament on such a platform, nor do I believe I would have been elected.
"My sacking has been a catalyst. It is sadly no longer possible for me to effectively represent my electorate in such an environment, despite my best endeavours.
"I thank the people of Stafford for the opportunity to have served them.
"I also thank everyone who has helped and guided me on this journey, particularly my family and my electorate team."
Mr Newman must now advise the Queensland Governor when to issue the writ for a by-election, although there is no rush.
In the past 30 years, writs have been issued as soon as three days after a resignation, with one case in 1988 taking up to 115 days.
The LNP currently hold the north Brisbane seat with a margin of 7.1%
Chris Davis resigns from Parliament on political donations
QUEENSLAND MP Chris Davis has resigned from parliament, citing new laws which go against the values of his electorate'.
Mr Davis was dumped by the premier as assistant health minister last week because he threatened to cross the floor on changes to the state's corruption watchdog and doctor contracts.
The final straw was the move to remove caps on political donations and left the chambers of Parliament last night before the laws were voted on.
"The passage of recent government legislation affecting critical aspects of our democracy goes contrary to my value system and that of the majority of my electorate," he said on a statement on his website.
"I would never have stood for parliament on such a platform, nor do I believe I would have been elected."
A by-election will be held in the north Brisbane seat.
