SALT LAKE CITY — A Utah Senate leader has unveiled a bill with major implications for Gov. Spencer Cox's emergency powers, as well as politicians' ability to override state and local public health orders. Senate Majority Leader Evan Vickers' SB195 would limit the duration of a public health order to 30 days. It would only allow the Legislature to extend or terminate it. It also would give the Legislature the power to terminate an emergency earlier than that 30-day time period. It would prohibit the governor or the health department from declaring a new emergency for the same issue unless there are exigent circumstances like a "significant change" after expiration that "substantially increases the threat to public safety or health," according to the bill. It would require a public legislative meeting to evaluate whether to extend the health order at the request of the health department.
