An essential function of the Parliament of Tasmania is to legislate, or pass new or amended Tasmanian laws (Bills).  The majority of Bills originate in the House of Assembly, with most Bills introduced by the Minister. This reflects the need for the Executive to seek the approval by the Legislature for proposed government legislation. In practice, most Bills pass the Parliament of Tasmania.

However, it should be noted that Members of the Legislature have the ongoing power to hold the Executive to account when debating and voting on government legislation. Any Bill, including Government Bills, must receive a majority support in both Houses to become an Act of Parliament. The defeat of Government Bills could place enormous political pressure on the Government of the day if it is perceived they have lost the ‘confidence’ of the House or the ability to pass government legislation.
