Denver (AP) -- Attorneys are expected to deliver final arguments in a lawsuit challenging how Colorado funds it's education system. The lawsuit against the state claims that Colorado has violated it's constitutional promise to provide a "thorough and uniform" education system and poor communities are at a disadvantage. State officials say Colorado has more than doubled spending on public education since 1994 and more than 40% of the budget now goes to education. Closing arguments are expected Friday afternoon in Denver District Court. A judge will rule in several weeks. Colorado officials warn that education will take up most of the budget if the state loses. But the plaintiffs say they're not seeking a monetary amount but for a court declaration saying Colorado has violated it's constitution and for funds to be used where they're needed most.
