Before a bill can become law, the Royal Assent is required. The governor-general acts on the monarch's behalf; in theory, he or she may grant the Royal Assent (making the bill law), or withhold the Royal Assent (vetoing the bill). By modern constitutional convention, however, the Royal Assent is invariably granted, and bills are never disallowed. A law comes into effect from the date the governor-general signs the bill.
