I want to know the answer to the following question:
What is used to determine whether federal judicial power extends to formulating binding precedent?
All the background I'm provided with is that "This is where the act of deciding a case becomes a limited form of lawmaking in itself, in that an appellate court's rulings will thereby bind itself and lower courts in future cases (and therefore also impliedly binds all persons within the court's jurisdiction).". Is that enough to answer the question?
Answer: no
