Good analysis from Laura Belin at Bleeding Heartland:
Republican lawmakers intended to prohibit schools, cities, and counties from requiring masks when they amended an education bill on the final day of the legislature’s 2021 session. But House File 847, which Governor Kim Reynolds rushed to sign within hours of its passage, was not well crafted to accomplish that goal.
An apparent drafting error opened the door for the mask order Iowa City Mayor Bruce Teague announced on August 19, with the full support of the city council.
Most news organizations missed the care this order was crafted with and followed with stories focused on Iowa City defying state law.
Despite Gov. Kim Reynolds maintaining that cities cannot issue such orders, the question hasn’t actually been tested in court.
