Abraham Lincoln to Joseph Gillespie, 7 February 18581
Hon: J. GillespieMy dear Sir
Yesterday morning the Court overruled the Demurrer to Hatch’s Return in the mandamus case–2 McClernand was present, said nothing about pleading over; and so I suppose the matter is ended–3
The court gave no reason for the decision; but Peck tells me confidentially that they were unanamous in the opinion that even if the Govr had signed the Bill purposely, he had the right to strike his name off so long as the bill remained in his custody & control4
Yours as everA. Lincoln5

2The mandamus case under discussion is People ex rel. Lanphier & Walker v. Hatch. A mandamus is a writ by which a court exercises its authority over a public official and compels them to perform an official duty. In this instance, the official was Illinois Secretary of State Ozias M. Hatch, who had been sued in the Illinois Supreme Court for a writ of mandamus to furnish state printers Lanphier & Walker of the Democratic Illinois State Register with a true copy of an 1857 bill apportioning representation in the Illinois General Assembly. The bill had been drafted and supported by the Democrats with an eye towards maintaining their party’s majority in the General Assembly. The Illinois House of Representatives passed the bill on February 16, 1857, and the Illinois Senate concurred on February 18. Republican Governor William H. Bissell mistakenly signed the bill then cancelled his signature after his secretary had already reported his approval to the House. Hatch was represented in this case by Lincoln, Orville H. Browning, and Jackson Grimshaw. Neither Gillespie nor Gustave P. Koerner were attorneys of record on this case, although Lincoln had earlier written similar letters to both requesting their consultation on the matter.
A demurrer is an exception by either party of a lawsuit to the points of law made by the other party. Judges either sustain or overrule the demurrer, and if the demurrer is overruled, the demurring party can re-plead on the facts of the case. In People ex rel. Lanphier & Walker v. Hatch Secretary of State Hatch had answered the charges against him with a return in which he stated that Governor Bissell had never intended to approve the apportionment bill, had stricken his signature and issued a veto when he realized his mistake, and that Hatch himself had never had possession of the bill prior to Bissell’s signature being cancelled. John A. McClernand, one of the Democratic attorneys representing the plaintiffs, had demurred this return on the grounds that it was insufficient in law.

4Illinois Supreme Court Chief Justice John D. Caton stated in the opinion on this case that the apportionment bill had never become law because it had remained in Bissell’s possession until he realized his mistake and struck his signature. Justice Sidney Breese entered a separate opinion on the case in which he agreed on this point and maintained that government departments had the right to reconsider a decision as well as the power to correct mistakes. Breese further argued that since the bill remained in Bissell’s custody until he discovered his error, the governor was only bound by his final action upon a bill, in this case returning it with his signature cancelled and with an objection, rather than by the actions of his secretary in reporting the governor’s approval.
