Prior to the adoption of Ord. 18006 on 03/01/2004, Section 4-16 read as follows.

In prosecutions under this chapter, there is a rebuttable presumption that a container marked or labeled as containing an alcoholic beverage actually contains the described alcoholic beverage. This rebuttable presumption applies to both open and sealed containers.  This rebuttable presumption applies only in cases where a sample of the contents of the container has been preserved and is available to the defendant for testing.

(Ord. No. 17600, § 1, 2-17-03)
