I’d think that the big “CIRCUIT COURT, D. MARYLAND” at the top of the decision would be a tip off.

Here is a copy of an 1863 report of the Merryman case. Sent to me by private email from nolu chan. The image is page 57 of "Prisoner of State," by Dennis A. Mahony, published in 1863.

In the reference I cited for Hartnett, Hartnett noted that the compilation of cases in Federal Cases that listed Merryman as a District Court case was not published until 1894. An error by the compiler.
