How do you deal with false claims of accessibility conformance?

 
Could someone please tell me how the W3C or WAI view websites that claim to
conform to the WAI Guidelines when clearly they do not. Eg.
http://www.tafe.sa.edu.au/Default.aspx?tabid=773

How can a site claim WAI conformance to any priority level when the html and
css do not pass validation?

Their claim is:

"W3C Web Content Accessibility Guidelines. All pages on the site have been
reviewed and comply with most  priority 1 guidelines to the best of our
knowledge."
