Arizona state legislators and the state superintendent of public instruction want to be freed from federal court oversight of the state's programs for English learners. They've been ordered by a lower court judge to spend potentially hundreds of millions of dollars to comply with rulings in a 17-year-old case.

Parents of students attending southern Arizona's Nogales Unified School District sued the state in 1992, contending programs for English-language learners in Nogales were deficient and received inadequate funding from the state.

In 2000, a federal judge found that the state had violated the Equal Educational Opportunities Act's requirements for appropriate instruction for English-language learners. He ordered state legislators to create a plan to provide sufficient funds and placed the state's programs for non-English speaking students under court oversight.

Since then, the two sides have fought over what constitutes compliance with the order. Arizona has more than doubled the amount that schools receive per non-English speaking student and taken several other steps prescribed by the No Child Left Behind Act, a broader education accountability law passed by Congress in 2002.

Plaintiffs say that's not enough to comply with federal law and a judge agreed. But the state appealed, and now the high court will answer the question.
