To read the full Supreme Court decision in the foreign-copyright case (Golan v. Holder), go here.
Be sure to read the dissent by Justice Breyer, which kicks in after page 41. He alone on the court seems to get that the Constitution recognized copyright as a mechanism to provide for the general benefit of society and not to create a property right for certain individuals.
May some future court come around to that understanding.
