“My point as others have made if there is no agreement, or compromise possible, one has to be able to pull rank, this isn’t something anyone can argue with otherwise a lot of disagreements would never be finalized.”
I disagree. Neither has the right to ‘pull rank’. This is exactly the situation where one should consult their rav, and let him decide, because neither of them is competent enough to make the decision on their own, nor has the right to.
