What other courts are there in the United States that must follow the decisions of the Supreme Court?

Answer 1

ALL the other courts must follow the Supreme Court.

They are the supreme court of the land and the last word in interpreting or ruling on issues of law or constitutional questions.

Answer 2

The Supreme Court of the United States is the highest court in the land. All Supreme Court decisions must be followed by all the lower courts, until that decision is overturned, if it ever is.
Example--In Plessy v Ferguson, the Supreme Court ruled that segregation was legal. Other courts followed that decision until the case of Brown v Board of Education reversed the Plessy v Ferguson decision and declared segregation unconstitutional.

Answer 3

That's why it's called the "Supreme" court - it has supremacy over all other courts in the US.

Answer 4

All other courts.
