A call to introduce a charge of corporate manslaughter from the families of 29 miners who died in the Pike River mine could be debated in Parliament if a Labour Party bill is drawn from the ballot.
A members' bills ballot will be held today and could see Labour's list MP Andrew Little's bill to amend the Crimes Act drawn.
It would allow companies to be charged with corporate manslaughter in cases of workplace deaths that are caused by failures at the board and senior management level.
Under the proposed bill a company or organisation could be fined up to $10 million, directors or senior manager could be sent to prison for 10 years for corporate failure.
Companies and organisations found guilty of corporate manslaughter would have to publicise the conviction, including in their annual report.
