In 1764 and 1765, Britain raised taxes in the colonies to beef up the British budget and to pay for an increased military presence in the colonies. The
Stamp Act, for example, taxed all sorts of paper items, including legal documents,
newspapers, pamphlets, marriage licenses, and even playing cards. Colonists didn't
appreciate these taxes and insisted that only the colonial legislatures could raise the
colonies' taxes. They argued that they should not suffer from British taxation
without representation in the British Parliament. Why would the colonists' be so
concerned about the Stamp Act?

In 1765, the Stamp Act was passed, requiring all legal papers to be printed on special paper with an embossed tax stamp. Many colonies believed that they must not be required to pay such levies since they were enacted by Congress in England, rather than by their local colonial administrations.

They brought up the problem of revenue without participation and organised organisations across the colonies to fight the British government as well as nobles who wanted to use the colonies as a source of cash and raw commodities.

the answer would be logic.

in griswold v. connecticut (1965), the supreme court ruled that a state's ban on the use of contraceptives violated the right to marital privacy.
