NASHVILLE, Tenn. (AP) _ Tennessee Attorney General Robert Cooper has rendered a legal opinion that the state's charter school funding law is constitutional.

The Tennessean reports Cooper issued an opinion Monday that defends the 2002 law that determines how charter schools are funded.

The opinion conflicts with the conclusion reached by a Metro Nashville Public Schools attorney. The school district's attorney, John Borkowski, had said the law imposes financial burdens on local school districts in violation of the state constitution.

His opinion set off a debate about the cost of charter schools and led supporters and opponent to ask the state attorney general to weigh in.
