Happy to differ but there is only one legal test. As a military lawyer I dealt with these all the time. The legal standard has absolutely nothing to do with a church's position. What matters is if he has true and sincere religious belief. All exemptions are written this way because you don't want to go down the rabbit hole of telling people how to interpret their faith. There is a huge contingent of catholic bishops who say the vaccine should be refused because it was derived from aborted fetal tissue. It's not the ADs job to say "I believe the group of bishops who say catholics can get the exemption over the group that says you shouldnt."
now that doesn't mean he gets to go around coughing on everyone without a mask. The correct way to deal with the religious exemption is to err on the side of person requesting it (religious freedom being a fundamental right) and then put all sorts of conditions like constant testing, distancing, etc. If he violates the conditions, then he can be fired for cause. Any halfway competent AD should know this. WSU is going to lose the lawsuit and will be paying Rolovich a lot of money, especially since the school initially granted the exemption and Chung overturned it. The lawsuit (which Rolovich will win) will be 100% on Chung. He had a very easy way of accommodating the exemption while giving WSU and airtight reason to fire him for cause if he violated the accomodations. Any AD too dumb to know this, or so politically motivated he ignores basic steps that would make sure WSU was on firm ground if it terminated Rolovich, should not be a candidate for AD.
