What is the purpose of a summary hearing in a motor vehicle accident case where a driver has been found to have been impaired by alcohol while driving under the influence of alcohol?

In Gikas v. Zolin (1993) 6 Cal.4th 841, our high court explained that "[t]he express legislative purposes of the administrative suspension procedure are: (1) to provide safety to persons using the highways by quickly suspending the driving privilege of persons who drive with excessive blood-alcohol levels; [and] (2) to guard against erroneous deprivation [of that privilege] by providing a prompt administrative review of the suspension . . . ." (Id. at p. 847, italics added.) This is why administrative per se hearings are set up as "summary proceedings."
