One of the injuries that is mentioned in the Declaration of Independence is the following:
"He [the king] has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people."
The dissolution of representative houses is an instance of the King being above the law. It is also an instance of a lack of checks and balances and a disregard for the separation of powers. These are all important factors in the context of the Revolutionary period, as these complaints were addressed in the Articles of Confederation and later in the Constitution.
