The IHC is refusing to give up on its complaint about how children with an intellectual disability are treated at many schools.
The organisation says it took Crown Law three years to respond to its original complaint that children with a disability are discriminated against.
It says such children are sometimes refused enrolment, or sent home at lunchtime because there are no staff to care for them.
IHC also says it's disappointed with Crown Law's response that the issue is the responsibility of schools, because in its view it's the Government's responsibility.
IHC now wants the complaint to be heard by the Human Rights Review Tribunal.
