“That interprets into the equivalent of saying that the posek is incompetent!”
I am not his/her lawyer (Rav Falk or the user you are disagreement with), but what whitecherry wrote was interpreted differently by me than the way you interpreted it. Rav Falk is a posek, probably a first class posek (I dont know him, or the sefer mentioned), but a posek can only answer a question, to the one who asks it, otherwise, all he can give, are the general rules. Unless of course he has ruach hakodesh and his sayings and writings contain the answers to every eventuality.
