I would think the Cruiseline would deny responsibility as well. And yes, that would not help his case, and I'm guessing the family is aware of this. It is only if they admit negligence and offer a settlement that it might take the blame off of the grandfather, which I'm assuming is what they are hoping for.
But I still think they are waiting and hoping for an outcome that would show negligence on the part of the Ship. If they were so sure that the ship is responsible, then why have they not filed yet? What else could they be waiting for?
If the family had proof of the ships negligence, why would they not be able to present that evidence in court? Especially if the defense is that he was not entirely at fault and something else is to blame.
Can't it still be used as evidence without it being made public? And if not, why?
Sometimes it is made public that the parties have agreed on a settlement but they do not disclose the amount or any details contained in the document.
Imo
