How According to Dickinson what taxes was Parliament justified in imposing on the colonies?

According to Dickinson, Parliament was justified in imposing taxes that were intended to regulate trade and ensure compliance with British law, such as duties on imported goods. However, he argued that direct taxes levied for revenue purposes, without colonial representation in Parliament, were unjust. Dickinson emphasized that taxation without representation violated the rights of the colonies and contradicted the principles of self-governance. Ultimately, he believed that while some regulation was acceptable, any tax aimed at raising revenue required the consent of the governed.
