To prove this situation-
Do a google search of any exemption you can think of. This will go to the AusLi site as the first or second hit. Open the link and check the details in the box in the upper right corner.
For argument sake.
EX05/09 This exemption has an expiry date of 2011. Look at the top right corner, it shows there the activity of the reg. Rescinded under the blanket instrument.
Methinks these FOIs are being too clever by half. Regretfully, how far do you have to go to prove these people do not know their job?
I'll keep at this for a bit longer to ensure my position.
EDIT to add...any exemption you open on the AusLi site will show on the left side of heading whether it is CURRENT, SUPERSCEDED or RESCINDED.
