Final answer:
The Stamp Act Congress's Declaration of Rights and Richard Bland's argument both opposed Parliament's right to tax the colonies without representation, citing constitutional rights and the rejection of 'virtual' representation as principal concerns.
Step-by-step explanation:
The argument for colonial rights found in the Stamp Act Congress's Declaration of Rights compares with the argument made by Richard Bland in that both reject the British Parliament's right to tax the colonies without representation, highlighting the principle of taxation without representation as unconstitutional. The Declaration of Rights issued by the Stamp Act Congress in 1765, asserted the colonists' rights as Englishmen to be free from taxes not levied by their own elected representatives. In a similar vein, Richard Bland's argument, which followed the Congress's sentiments, stressed the historical and legal precedents that supported the colonies' position that Parliament had no authority to tax the colonies internally without their consent.
The Stamp Act Congress's arguments were driven by a desire for economic relief and the protection of liberties under the British Constitution. Debating the legality of the Stamp Act, they issued a petition for repeal based on the idea that British subjects could not be taxed without their consent, which was a core element of the English Bill of Rights of 1689. This concern over British constitutional rights and the colonies' unique circumstances led to the widespread rejection of "virtual" representation that the British government offered as a justification for their legislative actions.
