Parents of an autistic child won a Supreme Court case granting them the right to self represent -
"...the right to go to court without a lawyer to challenge their public school district’s individualized plan for their child’s education.
The 7-to-2 decision involved an interpretation of the federal law that gives all children the right to a “free appropriate public education,” regardless of disability. Millions of children receive benefits under the law, the Individuals with Disabilities Education Act. Most federal appeals courts have ruled that when a dispute brings families and school districts into court, the parents cannot proceed without a lawyer."
