A blue law Most have been repealed, declared unconstitutional or are simply unenforced, although prohibitions on the sale of alcoholic beverages, and occasionally almost all commerce, on Sundays are still enforced in many areas. Blue laws often prohibit an activity only during certain hours and there are usually exceptions to the prohibition of commerce, like grocery and drug stores. In some places blue laws may be enforced due to religious principles, but others are retained as a matter of tradition or out of convenience. Contrary to popular belief, there is no evidence to support the assertion that the blue laws were originally printed on blue paper.
