Ben was a partner in an accounting LLP with four other partners. He contracted in the name of the LLP to buy a new computer system without consulting his fellow partners. They object to the purchase because they think their existing system can get them through one more tax season. Ben believes the new system will help them work more efficiently, so they can solicit more clients, or get along with fewer accountants. The other partners notify the seller they don't want the system and the seller claims it will sue for breach of contract if they don't go through with the deal. Who is liable to whom for what if the LLP doesn't go through with the purchase?
