Gardner v. Bonestell‪.‬

"That where persons in good faith and for a valuable consideration have purchased lands of Mexican grantees or assigns, which grants have subsequently been rejected, or where the lands so purchased have been excluded from the final survey of any Mexican grant; and have used, improved and continued in the actual possession of the same as according to the lines of their original purchase, and where no valid adverse right or title (except of the United States) exists, such purchasers may purchase the same."
