Part 1  Introduction

alternative information for users who cannot access frames or scripts; tables that are dif-

ficult to decypher when linearized; or sites with poor color contrast.

A tool provided to assess the WWW standards is BOBBY (

 www.cast.org/learningtools/

Bobby/index.html

).

In 2000, Bruce Maguire, a blind Internet user who uses a refreshable Braille display, 



brought a case against the Sydney Organising Committee for the Olympic Games. Maguire 

successfully demonstrated deficiencies in the site which prevented him using it adequately, 

which were not successfully remedied. He was protected under the 1992 Australian Disability 

Discrimination Act and the defendant was ordered to pay AU$20,000. This was the first case 

brought in the world, and it showed organisations in all countries that they could be guilty of 

discrimination if they did not audit their sites against accessibility guidelines. Discrimination 

Acts are now being amended in many countries to specifically refer to online discrimination.
