Churches in California and Minnesota, backed by a conservative legal group, filed lawsuits this week against the governors of their states challenging restrictions imposed due to the coronavirus outbreak that they contend are violations of religious liberty. They’re the latest in a long series of legal challenges, many of them in California, pitting clerics and houses of worship who believe they should be exempt from certain restrictions on public gatherings against governors who insist the measures are needed to rein in the pandemic. Most of the suits have been rebuffed; some have succeeded.
