I'd just like to say that this amendment came about through broad consultation with the perceptual disability community, that this indeed is not as clear as the government would like it to sound. This is responding to what they are saying. They are saying this is not as clear for them as it could be. This is why we are looking for this amendment. It's for the sake of clarity and to make sure there are no grey zones.
On March 13th, 2012. See this statement in context.
