They could reject it, but it would be perfectly justifiable for the party who sent the death duel invitation to battle them and teach them a lesson. As long as the latter did not kill or cripple them, they could do anything they want.

As for the general duel invitation, once it was sent out, the other party must accept it as soon as they see it when they come out of closed-door cultivation.
