The parties shall include among the issues to be briefed: (1) whether the plaintiff assignee of the mortgage on the property in question had standing to assert the due process rights of its assignor, which was formerly known as BankBoston, NA; and, if so, (2) whether BankBoston’s due process rights were violated by the defendants’ mailing of notice to FNB — the entity into which BankBoston had merged and to which it had changed its name — at FNB’s address, rather than to the Boston address listed on BankBoston’s mortgage assignment.
