Portrait of George Shiras, Jr. George Shiras, Jr. Blackburn v. Portland Gold Mining Company…

If A hold land under a patent from the United States or a Spanish grant ratified by treaty, and his heirs, devisees, or assignees dispute as to which have the best title under him, this does not make a case for the jurisdiction of this court under the twenty-fifth section of the judiciary act. If neither the validity nor the construction of the patent or title under the treaty is contested, if both parties claim under it, and the contest arises from some question without or dehors the patent or treaty, it is plainly no case for our interference under this section.

A cause cannot be removed from a state court simply because, in the progress of the litigation, it may become necessary to give a construction to the Constitution or laws of the United States. The decision of the case must depend upon that construction. The suit must, in part at least, arise out of a controversy between the parties in regard to the operation and effect of the Constitution or laws upon the facts involved.

If the parties to the controversy were citizens of different states, and if the matter in dispute exceeded the sum or value of $2,000, then the claimant might elect to commence proceedings in a Federal or in a state court, because either would be competent to determine the question of the right of possession. But if the usual conditions of Federal jurisdiction did not exist, that is, if there was no adverse citizenship, and if the matter in dispute did not exceed $2,000, then the party claimant could proceed in a state court.
