It is the intent of the Legislature that the power conferred in this chapter shall be liberally construed. The provisions of this chapter or subsequent amendment are severable. If any section, subdivision, paragraph, sentence, clause, or phrase of this chapter should be declared or held unconstitutional or invalid for any reason, such unconstitutionality or invalidity shall not affect the validity of any other provision of this chapter. The Legislature hereby declares that it would have enacted each other such section, subdivision, paragraph, sentence, clause, or phrase of this chapter irrespective of the fact that one or more sections, subdivisions, paragraphs, sentences, clauses, or phrases has been declared unconstitutional or invalid. Provided further that any such finding of invalidity or unconstitutionality shall not invalidate, affect or impair pool quotas and production bases heretofore issued under the Gonsalves Milk Pooling Act or pooling plan promulgated thereunder.
