Until the Governor has acted on a bill, the General Assembly may, by concurrent resolution presented in the house of origin, adopted by both houses and approved by the Governor, recall the bill for further consideration, in which case it may be again amended and passed by both houses in the amended form and again sent to the Governor; or it may be returned to the Governor without amendment. The latter is done by concurrent resolution, likewise originating in the house of origin.
