Defendant W. R. Grace & Co.--Conn. (“Grace”) submits this Memorandum of Law in support of its motion for relief from the Court's previous choice of law determination, based on the Court's inherent authority to modify an interlocutory ruling in the interest of justice. Because choice of law is a substantive matter that directly affects the outcome of cases, courts must be particularly vigilant during the entire pendency of a case to ensure that the proper law is applied.
