I'd be curious to know to what extent courts in other countries seek confirmation in the opinions of the United States. Do these justices propose imposing U.S. values on other countries in the name of globalism or merely imposing the values of other countries on us?
Actually, Australian courts regularly use U.S. precedent when there is not relevant Australian precedent.
And, it was quite customary, and unexceptional for U.S. courts to use British precedents (esp. those set pre-U.S. independence), particularly in matters relating to common law.
