A consumer lease entered into before July 1, 2003, and the rights, duties and interests resulting from it may be terminated, completed or enforced as required or permitted by any statute, rule of law or other law amended, repealed or modified by sections 42-270 to 42-271a, inclusive, and 42-390 to 42-434, inclusive, as though the repeal, amendment, or modification had not occurred. However, sections 42-270 to 42-271a, inclusive, and 42-390 to 42-434, inclusive, apply when, after July 1, 2003, a consumer lease is satisfied and replaced by a new lease undertaken by the same lessee for the same goods.
