PHOENIX (AP) — A federal judge ruled Friday that Arizona has made vast gains in teaching foreign students English and is no longer violating a federal law requiring states to overcome language barriers in schools, resolving a decades-old discrimination lawsuit.

U.S. District Judge Raner C. Collins’ ruling states that the case originally filed in 1992 on behalf of children and parents in the Nogales School District no longer has statewide reach because Arizona’s recently crafted English language program varies from county to county. Collins’ ruling comes more than two years after he heard evidence in the case.
