In Australia, a technical issue arose with the royal assent in both 1976 and 2001. In 1976, a bill originating in the House of Representatives was mistakenly submitted to the Governor-General and assented to. However, it was later discovered that <answer>it had not been passed by each house</answer>. The error arose because two bills of the same title had originated from the house. The Governor-General revoked the first assent, before assenting to the bill which had actually passed. The same procedure was followed to correct a similar error which arose in 2001.
What protocol was not followed in 1976 when a bill was mistakenly assented?
