In the case of Dahn v. Davis, Agent, Etc., 1921, the United States Supreme Court was asked to consider whether a lower court had jurisdiction over a suit brought by an individual against an agent of the federal government. The plaintiff in this case was seeking damages for alleged wrongful acts committed by the defendant while acting as an agent for the U.S. Shipping Board Emergency Fleet Corporation during World War I. The Supreme Court ruled that it did not have jurisdiction because Congress had not explicitly provided for such suits in its legislation establishing and governing these wartime agencies. Therefore, any claims against agents or employees of these organizations needed to be pursued through administrative channels rather than through lawsuits in federal courts.

The dissenting opinion in the case of Dahn v. Davis, Agent, Etc., 1921 is not readily available or well-documented in public records. This could be due to the age of the case and limitations on historical legal documentation during that time period. Therefore, a summary cannot be provided without further information or access to more comprehensive legal archives.
