<P> The Eleventh Amendment (1795) specifically prohibits federal courts from hearing cases in which a state is sued by an individual from another state or another country, thus extending to the states sovereign immunity protection from certain types of legal liability . Article Three, Section 2, Clause 1 has been affected by this amendment, which also overturned the Supreme Court's decision in Chisholm v. Georgia . </P> <P> The Sixteenth Amendment (1913) removed existing Constitutional constraints that limited the power of Congress to lay and collect taxes on income . Specifically, the apportionment constraints delineated in Article 1, Section 9, Clause 4 have been removed by this amendment, which also overturned an 1895 Supreme Court decision, in Pollock v. Farmers' Loan & Trust Co., that declared an unapportioned federal income tax on rents, dividends, and interest unconstitutional . This amendment has become the basis for all subsequent federal income tax legislation and has greatly expanded the scope of federal taxing and spending in the years since . </P> <P> The Eighteenth Amendment (1919) prohibited the making, transporting, and selling of alcoholic beverages nationwide . It also authorized Congress to enact legislation enforcing this prohibition . Adopted at the urging of a national temperance movement, proponents believed that the use of alcohol was reckless and destructive and that prohibition would reduce crime and corruption, solve social problems, decrease the need for welfare and prisons, and improve the health of all Americans . During prohibition, it is estimated that alcohol consumption and alcohol related deaths declined dramatically . But prohibition had other, more negative consequences . The amendment drove the lucrative alcohol business underground, giving rise to a large and pervasive black market . In addition, prohibition encouraged disrespect for the law and strengthened organized crime . Prohibition came to an end in 1933, when this amendment was repealed . </P> <P> The Twenty - first Amendment (1933) repealed the Eighteenth Amendment and returned the regulation of alcohol to the states . Each state sets its own rules for the sale and importation of alcohol, including the drinking age . Because a federal law provides federal funds to states that prohibit the sale of alcohol to minors under the age of twenty - one, all fifty states have set their drinking age there . Rules about how alcohol is sold vary greatly from state to state . </P>
