Covid Legal Authority
I found Indiana's 2014 policy with legal authorities, which is far far more restricted than what it did in 2021. See https://www.in.gov/isdh/files/Dr__Adams_-_Implementing_Isolation_and_Quarantine_October_30_2014.pdf.
An HT article of March 2021 says that three counties in Indiana defied the Governor's illegal mask mandate. " Indiana Gov. Eric Holcomb, a Republican, used an executive order to institute a mask mandate that took effect July 27. The blowback was almost instantaneous; sheriffs in Sullivan, Hamilton, Delaware and Johnson counties immediately said they would not enforce the order because the General Assembly hadn’t passed a bill for it....
Holcomb has consistently renewed the mask mandate since July, even if he dropped possible criminal penalties for violators before it took effect.
Additionally, the mandate gave gubernatorial candidate Donald Rainwater, a Libertarian, a boost, because he was against Holcomb’s mandatory mask mandate. Rainwater received more than 11% of the statewide votes for governor."
