In the case of Smyer et al. v. United States in 1926, the Supreme Court ruled on a dispute involving oil and gas leases on public lands. The plaintiffs, who were oil companies and individuals involved in the petroleum industry, argued that they had been unfairly denied access to these resources by the Secretary of Interior's interpretation of certain provisions within leasing laws. They claimed this denial constituted an unlawful taking without just compensation under Fifth Amendment rights. The court disagreed with their assertion, ruling that no property rights could be established merely from filing applications for permits or leases before any actual approval was given by government authorities. Therefore, there was no basis for claims of unjust deprivation as applicants did not have vested interests simply through application submission. Furthermore, it held that Congress has broad discretion over how public lands are managed and disposed; thus its decision to change policy direction regarding such matters does not constitute a violation against constitutional protections concerning private property rights. This verdict reinforced federal authority over resource allocation decisions related to public land use while also clarifying legal interpretations around what constitutes legitimate property interest deserving protection under law.

The dissenting opinion in the case of Smyer et al. v. United States argued that the majority's decision to uphold convictions for conspiracy to defraud the government was flawed due to insufficient evidence presented at trial. The dissent contended that while there may have been proof of a scheme or plan, this alone did not constitute an actionable conspiracy without clear evidence demonstrating intent and agreement among all parties involved in carrying out said plan. Furthermore, it was pointed out that some defendants were convicted solely based on their association with other conspirators, which violated principles of individual criminal responsibility and guilt by association rules under U.S law. This view held that mere knowledge or approval of illegal activities does not equate participation or agreement necessary for a conviction on conspiracy charges.
