The Constitution is an Act of British Parliament, so when a referendum is successful, does the British Parliament need to be notified?

Description

Hi, thanks for your question.

No. The British Parliament does not need to be notified or involved when Australia changes its Constitution through a referendum, even though the Australian Constitution was originally part of a British Act of Parliament.

A referendum is a vote to change the Australian Constitution. The process for conducting a referendum is contained in section 128 of the Australian Constitution. It does not include any requirement to notify the British Parliament or ask for permission. 

Australia has passed laws which give it constitutional independence from the British Parliament. This means the Australian Parliament can pass bills, including referendum bills, without any involvement of the British Parliament.
