Reform approach to Halacha

Does anyone know how the Reform movement (or other more liberal groups) defines its halacha? Do they create rulings as stringent as Conservative/Orthodox but just recognize that its not authoritative, or do they write more flexible rulings?

For example, do they say that you must kasher your dishware for Pesach, or do they say something less stringent like “Make sure that your dishware is free of chametz” and leave it up to individuals how they interpret that. Thanks.
