In the case of United States v. Chandler et al., 1972, the Supreme Court ruled on a matter involving federal jurisdiction over crimes committed in U.S. territories and possessions. The defendants were charged with conspiracy to import marijuana into the mainland United States from St. Thomas, Virgin Islands - an unincorporated territory of the U.S.. They argued that since both locations are under American sovereignty, they should not be prosecuted for importing drugs between them as it does not constitute "importation" within federal law's meaning. The court disagreed with this argument and upheld their convictions by ruling that Congress has broad powers to define criminal conduct in U.S territories and possessions under its authority given by Article IV of Constitution (Territorial Clause). It further clarified that these areas are considered foreign countries for purposes of drug enforcement laws due to their distinct legal status despite being part of US sovereign domain.

In the dissenting opinion for United States v. Chandler et al., Justice Douglas argued that the majority's decision to uphold a federal law prohibiting doctors from prescribing narcotics to addicts was an overreach of congressional power. He contended that this issue should be left up to individual states, as it pertains more closely to public health than interstate commerce. Furthermore, he expressed concern about the potential implications of such broad interpretations of Congress' Commerce Clause powers on civil liberties and state sovereignty. He also criticized the majority's reliance on Wickard v. Filburn (1942), arguing that it was not applicable in this case because unlike farmers growing wheat for personal use, doctors prescribing drugs do not significantly affect market conditions or prices.
