The laws of physics, ultimately. The FARs before that (though I can't
find a
specific rule, it would certainly be classified as "careless and reckless"
if
it led to an incident - it might be in the certification rules for
aircraft,
same as aerobatic stuff and equipment required.)


The FARs come before the laws of physics?



The FAA has made it clear
that unless the aircraft is certificated for known ice, you can't even
legally
enter forecast ice.


What law, other than a natural law, would such an action violate?
