ASL have no authority to refuse a candidate the use of documents printed from the CASA website. Indeed if they follow the rules to the letter, then I presume they will be aware of
http://www.casa.gov.au/fcl/exams/cyber/material.htm
"Self printed copies of CARs, CAOs and CAAPs downloaded from the CASA website are acceptable subject to the following:
* The documents are approved for use in the particular examination, and are secured in a ring bound folder.
* The CARs, CAOs and CAAPs do not contain manuscript material, and are in separate and clearly marked folders.
* The folders do not contain other documents or notes."
However, the biggest problem is simply the size of the docs - It will take a couple of forests to provide the amount of paper needed for the Regs and Orders.
If you know when you are going to sit the exams, you can order up-to-date copies on-line without the update service, and save about half of the cost.
