I am a missionary and I inform the Cherokee's of their rights
Well you are going to have to leave this land because the state of Georgia requires you to have a license to be on this land. You don't have one.
Well I am not leaving or getting a license.
Well then you are under arrest.
Well actually you can't. The Cherokees are allowing me to be here. I am also under orders of the federal government.
You can't do this.
Yes I can I am a state.
The state of Georgia has no right regulating the access to the Cherokee's land because the Cherokee nation is recognized as its own nation.
March 3, 1832
Georgia you can not make laws regulating access to the Cherokee's land. Only the federal government can do that.
John Marshall ruled in favor of Worcester. He basically said that the Cherokee nation was it's own sovereign entity and that Georgia could not pass laws that regulated the access to these lands. The ruling helped reestablished the power of the federal government in this case. More importantly, it expanded the rights of tribes.
