This legislation prohibited drunkenness and the sale of alcohol to minors, and required all liquor sellers to post a $2,000 bond (more than $30,000 in 2007 U.S. dollars). German - Americans fought the new law in the courts and at the ballot box . Although they lost challenges in the courts, they were able to elect a legislature friendlier to alcohol consumption .
