You do realize that the preamble actually mirrors the legislative intent of charters that is in the Charter Schools Act and the parent involvement is in the requirements for petitions? Neither have ever been questioned before.
As for the actual question, the question asks if the local and state bodies can authorize. The complaint is that the locals can "already" authorize. Well, according to the same opponents, the state can "already" authorize too (which is still legally challengeable). Why is everyone so afraid to ask the public to AFFIRM this?
