How did some colonists protest this law - stamp act 1765

   In Boston, Samuel Adams helped start an origination called the Sons of Liberty to protest against the stamp act. Protesters burned effigies-rag figures-representing tax collectors and destroyed houses belonging to royal officials. In October delegates from nine colonies met in New York at the Stamp Act Congress. They drafted a petition to the King and Parliament declaring that the colonies could not be taxed except by their own assemblies. In colonial cities, people refused to use the stamps. They urged merchants to BOYCOTT-(refuse to buy) British and European goods in protest.

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.
