Mate back to recurrent ground school for you.
Alternate law-
No pitch or bank protection.
High alpha prot and max alpha replaced by low speed stability (stall warning speed)
No alpha floor protection
I would have said it was exceedingly obvious that the protections inherent in normal law were not available in alt law, given that we are talking about an aircraft that stalled into the sea.
However those protections, or the lack of, do not alter the pilot's ability to control the aircraft. ie this was not a control issue.
