The party or coalition that can command a majority in the Legislative Assembly is invited by the Governor to form a government. That party or coalition's leader, once sworn in, subsequently becomes the Premier of Western Australia, and a team of the leader's, party's or coalition's choosing (whether they be in the Legislative Assembly or in the Legislative Council) can then be sworn in as ministers responsible for various portfolios. As Australian political parties traditionally vote along party lines, most legislation introduced by the governing party will pass through the House of Assembly.
