I want to know the answer to the following question:
What is a major implication of the Erie doctrine?
All the background I'm provided with is that "When hearing claims under state law pursuant to diversity jurisdiction, federal trial courts must apply the statutory and decisional law of the state in which they sit, as if they were a court of that state, even if they believe that the relevant state law is irrational or just bad public policy.". Is that enough to answer the question?
