The Corporation of New-Orleans v. Winter et al. was a case heard by the United States Supreme Court in 1816 that centered around whether or not the state of Louisiana had authority to grant land titles within its boundaries. The court found that it did, and ruled in favor of the corporation, holding that Congress had given Louisiana full power over all lands within its borders when it became a state in 1812. This decision established an important precedent for states' rights and their ability to control public lands within their own boundaries without interference from federal authorities. It also affirmed the right of individuals to hold valid title deeds issued by states even if they were granted before those states joined the Union as sovereign entities with exclusive jurisdiction over such matters.

In The Corporation of New-Orleans v. Winter et al., the Supreme Court was asked to decide whether a state law that allowed for the sale of property seized by creditors in order to pay off debts was constitutional. Justice Johnson, writing for the dissenters, argued that states have no power to pass laws which interfere with contracts made between individuals and corporations. He further argued that such interference would be an unconstitutional violation of private rights and liberties as protected under Article I Section 10 Clause 1 of the United States Constitution (the Contract Clause). Furthermore, he asserted that Congress has exclusive authority over interstate commerce and any attempt by a state legislature to regulate it is unconstitutional. In conclusion, Justice Johnson believed this particular law should not stand because it violated both individual rights as well as congressional powers granted under the US Constitution.
