Which constitutional issues did the sugar and stamp act raise in the mid 1760's?

The Sugar Act and Stamp Act of the mid-1760s raised significant constitutional issues regarding taxation without representation. Colonists argued that these acts violated their rights as Englishmen, as they were being taxed by a Parliament in which they had no elected representatives. This sparked a broader debate about the authority of Parliament over the colonies and the extent of colonial self-governance. Ultimately, these issues contributed to growing tensions that led to the American Revolution.
