In Sparrow v. Strong, the Supreme Court of the United States held that a state statute which authorized an individual to take possession of another's property without due process was unconstitutional. The case arose when William Sparrow attempted to repossess goods from John Strong after he had failed to pay for them in accordance with their contract. However, under a New York law at the time, if payment was not made within six months then ownership reverted back to Sparrow and no court action or notice was required before taking possession of the goods. The Supreme Court found this law violated both Article IV Section 2 and Amendment V of the U.S Constitution as it deprived individuals like Strong from their property rights without due process being followed first - namely notice and opportunity for hearing prior to any deprivation occurring. As such, they declared this state statute void on constitutional grounds and affirmed that all persons must be afforded procedural safeguards before having their private property taken away by others or government entities alike

In Sparrow v. Strong, the Supreme Court was asked to decide whether a treaty between the United States and Great Britain that allowed for fishing in certain waters off of Vancouver Island applied to Native Americans living on those lands. The majority opinion held that it did not, as they had never been considered citizens of either country and thus were not included in the terms of the agreement. However, Justice Field dissented from this decision, arguing that Native Americans should be treated equally under international law regardless of their citizenship status. He argued that since both countries had agreed to allow free access to these waters for all fishermen without discrimination based on race or nationality, then Native Americans should also have equal rights when it came to taking advantage of them. Furthermore, he noted that treaties are meant to benefit both parties involved and so denying one group access would ultimately harm everyone involved by creating an unequal playing field with regards to resources available within those waters.
