Lugo v. Holder, 783 F.3d 119 (2nd Cir. Apr. 9, 2015) (Whether an agency decision may permissibly be applied retroactively is determined by looking at five factors: (1) whether the case is one of first impression, (2) whether the new rule presents an abrupt departure from well-established practice or merely attempts to fill a void in an unsettled area of law, (3) the extent to which the party against whom the new rule is applied relied on the former rule, (4) the degree of the burden which a retroactive order places on a party, and (5) the statutory interest in applying a new rule despite the reliance of a party on the old standard.
