A few things:
1) According to Indonesian authorities AirAsia was NOT allowed to fly on Sundays.
2) Despite this, some kind of flight plan must have been filed somewhere for the flight to leave the ground at the airport of origin.
3) Does this in legal terms mean that the flight was allowed although it was not?
4) What would the insurance company make of it?
5) How will this discrepancy affect victims' families?
6) According to Singaporean authorities the flight was allowed to take place in Singaporean airspace to land on a Singaporean airport.
7) Does this in legal terms mean that if the wreck is found in Singaporean waters everything is OK, legally?
8) Or, consequently, does this mean that if the wreck is found in Indonesian waters everything is the opposite of OK, legally?
