A new trial has commenced in Arizona over long-standing disparities in school funding, a case that dates back to a 1994 Supreme Court ruling. The trial, which began on Tuesday, focuses on whether the state has failed to establish and fund minimum adequate facility standards for schools. The plaintiffs argue that Arizona has not met its constitutional obligation to provide a 'general and uniform' school system. The defense, represented by Republicans, contends that the current system is legal and sufficient. The outcome of this month-long trial could result in a landmark ruling on school facilities funding in the state. State lawmakers are being urged to fulfill their constitutional obligations.
