Wichita ? A federal appeals court has rejected a nonprofit group’s claim that science standards for Kansas public schools promote atheism.

The 10th U.S. Circuit Court of Appeals in Denver affirmed on Tuesday a lower court ruling that had dismissed the lawsuit brought by a nonprofit group calling itself Citizens for Objective Public Education.

At issue in the lawsuit are guidelines adopted in 2013 by the Kansas Board of Education that treat evolution and climate change as key scientific concepts.

The appeals court agreed with U.S. District Judge Daniel Crabtree that opponents of the standards had no standing to sue because they could not show an injury.

Its decision notes the standards themselves recommend objective curricula and allows districts the option not to adopt the standards or to teach alternative origins theories.
