What is the process of a double dissolution?

The process of a double dissolution refers specifically to the Governor-General dissolving both houses of Parliament, triggering a full election for all members of both the House of Representatives and the Senate. This constitutional mechanism is typically used when there is a deadlock between the two houses, often when the Senate refuses to pass legislation that has already been approved by the House of Representatives on multiple occasions.

During a double dissolution, both houses are dissolved simultaneously, which allows for a fresh election where voters can elect new members to both chambers. This process is significant as it can help resolve legislative gridlock and provide the government with a renewed mandate from the electorate.

In contrast, the other options do not accurately describe the constitutional process of double dissolution. For example, declaring all legislative actions null and void does not occur in this context; only certain legislative disagreements lead to this situation. Similarly, only dissolving the Senate while the House continues contradicts the essence of a double dissolution, which involves both houses. Lastly, the selection of interim members is not part of this process, as elections are held to fill these positions directly after the dissolution. Thus, B clearly captures the essence and purpose of a double dissolution in Australia’s parliamentary system.
