In his first message to the state legislature, newly elected Governor Bamberger identified enactment of prohibition legislation as the first duty of the legislature. Contending prohibition bills were introduced during the session. One, modeled on an Oklahoma law, called for a prohibition commissioner to enforce the law, banned all beverages containing in excess of one-half of one percent alcohol by volume, and allowed, under certain circumstances, for the search and seizure of alcoholic beverages without a search warrant. The other bill provided for enforcement by the governor and attorney general through the existing law enforcement system, raised the allowable alcohol content to two percent, and did not provide exceptions to the need for a search warrant. An uneasy compromise was passed with only one dissenting vote. The compromise legislation retained the one-half of one percent limit, but did not include the prohibition commissioner or the exceptions for search warrants. The law, signed by Governor Bamberger, went into effect on 1 August 1917. The law recognized that some products containing alcohol were legitimate; they included patented medicines, flavoring extracts, pure grain alcohol for scientific and industrial purposes, and sacramental wines.
