George Sutherland, Posadas v. National City Bank of New York…
“ In the Domenech Case we held that the national-banking laws extended to Puerto Rico; that a tax on a branch of a national bank is a tax on the bank; and that Puerto Rico, being a dependency of the United States, could not, except as permitted by R.S. § 5219, tax a national bank, since it is an agency of the United States. ”
