I learned a timely lesson earlier today.

Sitting in my car after leaving an appointment, I looked at Twitter to see if any there was any news of interest.

A number of media outlets and journalists were tweeting that a 19-gun salute was about to take place, at 4.59pm to be precise, outside Parliament House in Canberra.

Then I managed to forget things I used to know and proceeded to make a fool of myself. Well, I could argue only half a fool, but that’s a bit like being half mad or half pregnant.

I took issue with statements by others that the prorogation of Federal Parliament was about to take place. I was wrong. The Parliament was prorogued at 4.59pm. Here’s the explanation from the Parliamentary Education Office. Thanks to @2ricz.

Before dissolving the House of Representatives, the Governor-General issues a proclamation proroguing the Parliament. Prorogation is an ancient power of the British Crown adopted in the Australian Parliament as the means of bringing a session of Parliament to a close. A prorogation may take place separately from an election, but this rarely happens now except for ceremonial purposes. For example, in 1974 and 1977 the Parliament was prorogued when the Queen visited Australia which enabled Her Majesty to attend and open Parliament. When an election is called, the Prime Minister usually announces a dissolution and prorogation of Parliament at the same time before they are formalised by the Secretary to the Governor-General in a public ceremony in front of Parliament House. After the Parliament is prorogued and the House of Representatives dissolved, bills and other business before the House of Representatives and the Senate lapse and will need to be reintroduced. The government becomes a caretaker government and, by convention, does not make major decisions. The sittings of the Senate are terminated, but Senate Committees may still operate.

I took issue with statements by others that the Parliament was dissolved at 5.00pm. I was right. The House of Representatives was dissolved at 5.00pm but the Senate wasn’t. The Senate is only dissolved when there is a double dissolution and that hasn’t happened since 1987.

I took issue with the assertion that Parliament was “deferred”. I was right. As @ljLoch tweeted, whilst that might be a nice concept, Parliament is never deferred.

The lesson? As that old saying goes, sometimes it’s better to keep your mouth shut and be thought a fool than to open it and remove all doubt.
