CTLawyer,
“Dina Malchusa Dina………………….”
So was the decree for the Jews not to learn Torah and to attend Achashverushes party.
Some look at the mask laws as decrees, when the government starts deciding who can and who cannot be open, what congregations are ok and what should be banned without scientific reasoning this seems more like a decree. When the government decides what is essential and is selective when creating rules, this is not ok.
