To the Senate of the United States:
John H. Clack, a master commandant in the Navy of the United States, having rank as such from the 24th April, 1828, was on the sentence of a court-martial, which was approved by me, ordered to be dismissed from the service. On a reexamination of the record of the trial I am satisfied that the proceeding was illegal in substance, and therefore that the sentence was void.
To restore the party to the rights of which he was deprived by the enforcement of a sentence which was in law erroneous and void, I nominate the said John H. Clack to be a master commandant in the Navy of the United States, to take rank as such from the 24th April, 1828.
