No, according to Dickinson, Parliament was not justified in imposing taxes on the colonies, since he, along with many others at the time, argued that it was unfair to tax the colonies without offering them representation.
Step-by-step explanation:
Britain required new tax acts such as the Stamp Acts and the Sugar acts. Nevertheless, the settlers felt threatened by these new rules. Parliament forced the Townshend Act, which raised taxes on carried goods. According to John Dickinson, Parliament was supported in forcing the Stamp Act on the colonies.
