Section 6, ch. 85-285, in pertinent part provides that "[i]n the event that a federal court of last resort determines that it is unconstitutional for the Federal Government to withhold transportation funds from the state because the legal age of the sale, consumption, or possession of alcoholic beverages is under 21 years of age or if federal legislation is enacted to allow the drinking age to be lowered or modified from 21 years of age, it is the intent of the Legislature that the amendments to [this section] contained in this act shall be null and void and that [this section reverts] to the language existing . . . on June 30, 1985."
