Actually the PP v compton lawsuit lays out the legal argument for the relationship between aces and special education. Although the lawsuit was filed under 504 and ADA the argument is applicable to special education.
The presentation I made at the legal issues in special education conference was well received and many special education directors are focused on this issue.
for more information you might want to contact the plaintiffs attorneys with public council in California.
If you need specific information take a look at the powerpoint I have attached that outlines the legal argument.
