In granting a preliminary injunction, the court should not attempt to do what can be done only after a full hearing and final decree. System 99 v. System 101, 35 Cal.App.3d 170, 110 Cal.Rptr. 560 (1973); see Ford v. Civil Service Commission, 36 Colo. App. 55, 534 P.2d 829 (1975).. There was no stipulation that the hearing would be on both the preliminary and permanent injunction.
