In Commander-in-Chief v. Burton, the United States Supreme Court ruled that a military court had jurisdiction to try and punish an individual for desertion from the Union Army during the Civil War. The case involved William H. Burton, who was arrested in 1862 by order of Major General John A. Dix on charges of desertion from his regiment while it was stationed at Fort Monroe, Virginia. After being tried and convicted by a military commission appointed by Dix, he appealed to the U.S Circuit Court for Maryland claiming that he should have been tried in civil court instead of before a military tribunal because there were no laws authorizing such tribunals or providing punishment for deserters under martial law at that time in Maryland or elsewhere within its borders except where troops are actually engaged in battle with an enemy force. However, the Supreme Court rejected this argument and held that Congress had authorized such courts as part of its war powers granted under Article I Section 8 Clause 14 of the Constitution which gives Congress authority “to make Rules concerning Captures on Land & Water” including those related to prisoners taken during wartime operations against enemies foreign or domestic; thus affirming both Dix's appointment power over commissions as well as their right to try individuals like Burton accused of violating orders issued pursuant thereto even if they did not take place directly on battlefields themselves but rather away from them while still serving with forces actively engaged therein

In Commander-in-Chief v. Burton, the Supreme Court was tasked with deciding whether a military officer could be tried by a civil court for an alleged crime committed while on active duty. The majority opinion held that such trials were not permissible under the Constitution and laws of Congress, as they would interfere with the President's authority to maintain discipline in the armed forces. In his dissenting opinion, Justice Grier argued that this interpretation of constitutional law was too broad and would lead to dangerous consequences if applied without limitation or restraint. He noted that it is essential for both civilian courts and military tribunals to have jurisdiction over criminal acts committed within their respective jurisdictions; otherwise there will be no check against abuses of power by either branch of government. Furthermore, he argued that allowing only one branch exclusive control over all matters relating to national defense would create an imbalance between civil liberties and executive authority which could ultimately threaten our system of checks and balances established by our Founding Fathers.
