Owen J. Roberts, Creek Nation v. United States…
“ Its erroneous application and the consequent disposals of the lands to adverse holders constituted the taking by th United States. The petitioner is entitled to the present full equivalent of the value of the lands, without improvements, as of the date of the patents of the various parcels, if, as we assume, the patent in each instance issued promptly after the delivery of the final certificate; but if a substantial interval elapsed between the date of certificate and of patent, then as of the date of the certificate. ”
