It's been a long day and so I don't think I understand what you're saying. Are you talking about situations like Strauss v. Belle Realty- where there was no duty to protect all users of their electricty for injuries during a blackout? It was limited only to those in privity of the contract because otherwise the group able to sue would be too large and undefined.There, I would say that a duty was not found for public policy reasons. I think it's related to the Hand formula, in that they're both economic reasoning but if you phrase it as "there was no duty" as opposed to "there was no breach of that duty" you set a different kind of precedent. What do you think?
Just fyi, I brought this up to my professor during office hours today and he gave me a very quizzical look. He said in very plain terms that the question of duty comes first, then the Hand formula is used to evaulate a breach of that duty of due care. If you have taken precautions that are not unnecessarily expensive, then you have met your duty.
the way i see it...duty of reasonable care is owed to 'everybody'B<PL goes to establish what that reasonable care is, in effect shifting where the duty is breached at.it gets confusing because it can be said that one has a duty not to breach his duty. both have reasonable care in their definitions and it gets circular...
