In the 1893 case Tucker v. United States, the Supreme Court ruled on a dispute involving land ownership in California. The plaintiff, Tucker, claimed that he had purchased a parcel of land from an individual who had acquired it through preemption rights under federal law. However, before this person could receive their patent (official ownership document), they sold it to Tucker. Meanwhile, another party also claimed ownership of the same plot of land under Mexican Land Grant laws and received their patent first due to administrative delays with Tucker's claim. The court held that even though there was delay in issuing patents for both parties involved due to bureaucratic reasons beyond their control; priority should be given based on when each party established valid claims over the property according to respective laws - not by when they received official documentation (patent). In this case since Mexican Land Grant claimant got his title validated first as per relevant laws despite receiving patent later than Mr.Tucker; he was deemed rightful owner by court thereby dismissing Mr.Tucker's appeal against lower courts' similar rulings.

In the dissenting opinion for Tucker v. United States, it was argued that the majority's decision to uphold a conviction based on evidence obtained through an unauthorized search and seizure violated the Fourth Amendment rights of the defendant. The dissenting justices believed that any evidence procured in such a manner should be deemed inadmissible in court, regardless of its relevance or potential impact on the case outcome. They contended that allowing this type of evidence not only undermines individual privacy rights but also incentivizes law enforcement officials to conduct illegal searches with impunity, thereby eroding public trust and confidence in legal institutions. Furthermore, they expressed concern about setting a dangerous precedent where constitutional protections could be easily circumvented under the guise of criminal investigation.
