In the case of Ann Buyck, Widow of Don Augustin Buyck, Deceased and the Unknown Heirs of Said Buyck v. The United States, Ann was appealing a decision made by the Court of Claims which denied her claim for compensation from the government due to land that had been taken away from her late husband in 1836. She argued that she should be compensated for this taking because it violated both state law and federal treaties with Native American tribes. However, the Supreme Court ruled against her on grounds that there was no legal basis for such a claim since Congress had not authorized any payment or compensation at all. Furthermore, they found that even if there were some sort of violation committed by either party involved in this dispute - whether it be state law or treaty rights - then it would have been up to Congress to decide how much money should be paid out as recompense rather than leaving it up to judicial discretion. Ultimately, Ann's appeal was rejected and she did not receive any form of monetary compensation from the government for what happened back in 1836 when Don's land was taken away without his consent.

In the case of Ann Buyck, widow of Don Augustin Buyck, deceased, and the unknown heirs of said Buyck v. The United States, a dissenting opinion was issued by Justice McLean. He argued that Congress had no authority to pass legislation granting land in Florida to individuals who served during the Seminole War as it would be an unconstitutional exercise of power under Article I Section 8 Clause 17 which grants Congress exclusive right to legislate on public lands. Furthermore he argued that even if such a law were constitutional it could not apply retroactively since there was no evidence that any individual involved in this particular case had been aware or informed about its existence prior to filing their claim for compensation from the government for services rendered during the war. Finally he noted how unfair it would be for those who did serve but were unaware or unable to take advantage of such laws due solely because they lacked knowledge at time when they should have acted upon them.
