I want to know the answer to the following question:
When was the doctrine of Erie Railroad Co. v. Tompkins put into effect?
All the background I'm provided with is that "Only in a few narrow limited areas, like maritime law, has the Constitution expressly authorized the continuation of English common law at the federal level (meaning that in those areas federal courts can continue to make law as they see fit, subject to the limitations of stare decisis).". Is that enough to answer the question?
Answer: no
