Blue Law

Blue laws, also known as Sunday laws, are laws designed to restrict or ban some or all Sunday activities for religious reasons, particularly to promote the observance of a day of worship or rest. Blue laws may also restrict shopping or ban sale of certain items on specific days, most often on Sundays in the western world. Blue laws are enforced in parts of the United States and Canada as well as some European countries, particularly in Austria, Germany, Switzerland, and Norway, keeping most stores closed on Sundays.

In the United States, the U.S. Supreme Court has held blue laws as constitutional numerous times, citing secular basis, even though the origin of the blue laws was for religious purposes. Blue laws are technically classed as "mala prohibita" or "wrong [as or because] prohibited" (as opposed to "mala in se" or "wrong or evil in itself"). Most blue laws have been repealed in the United States, although many states still ban the sale of alcoholic beverages or cars on Sundays. Bergen County, New Jersey is notable for their blue laws banning the sale of clothing, shoes, furniture, home supplies and appliances on Sundays kept through county-wide referendum.

The very first known law regarding Sunday labor was in 538 at the Third Council of Orléans.

The first occurrence of the phrase blue laws so far found is in the New-York Mercury of March 3, 1755, where the writer imagines a future newspaper praising the revival of "our Connecticut's old Blue Laws". In his 1781 book General History of Connecticut, the Reverend Samuel Peters (1735–1826) used it to describe various laws first enacted by Puritan colonies in the 17th century that prohibited various activities, recreational as well as commercial, on Sunday (Saturday evening through Sunday night). Sometimes the sale of certain types of merchandise was prohibited, and in some cases all retail and business activity.

Contrary to popular belief, there is no evidence that blue laws were originally printed on blue paper. Rather, the word blue was used in the 17th century as a disparaging reference to rigid moral codes and those who observed them, particularly in blue-stocking, a reference to Oliver Cromwell's supporters in the parliament of 1653. Moreover, although Reverend Peters claimed that the term blue law was originally used by Puritan colonists, his work has since been found to be unreliable. In any event, Peters never asserted that the blue laws were originally printed on blue paper, and this has come to be regarded as an example of false etymology, another version of which is that the laws were first bound in books with blue covers.
