Why was the tea act of 1773 passed?

ConsequencesThe Boston Tea Party appalled British political opinion makers of all stripes. The action united all parties in Britain against the American radicals. Parliament enacted the Boston Port Act, which closed Boston Harbor until the dumped tea was paid for. This was the first of the so-called Coercive Acts, or Intolerable Acts as they were called by the colonists, passed by Parliament in response to the Boston Tea Party. These harsh measures united many colonists even more in their frustrations against Britain, and were one of the many causes of the American Revolutionary War.
The Taxation of Colonies Act 1778 repealed the tea tax and others that had been imposed on the colonies, but it proved insufficient to end the war. The Tea Act became a "dead letter" as far as the Thirteen Colonies were concerned, and was formally removed from the books in 1861.

Opposition to the nra came to a head in 1935, when the conservative supreme court declared the agency unconstitutional, claiming the nra gave the executive branch regulatory powers that belonged exclusively to congress. this decision began a series of court decisions that overturned key elements of the new deal.
