How were colonists were justified in the actions the evening of the Boston tea party?

Colonists justified their actions during the Boston Tea Party as a form of protest against the British government's imposition of taxes without representation. The Tea Act of 1773 granted the British East India Company a monopoly on tea sales, which many colonists viewed as an infringement on their economic rights and liberties. By dumping the tea into Boston Harbor, colonists aimed to express their anger and resistance to what they considered oppressive taxation and the erosion of their rights as Englishmen. This act of defiance was seen as a necessary step in the struggle for independence and self-governance.
