In the 1943 case United States v. Hellard, the Supreme Court of the United States ruled on a matter concerning military law and court-martial jurisdiction. The respondent, Hellard, was convicted by a general court-martial for desertion during peacetime but his conviction was set aside by a federal district court due to lack of jurisdiction. The government appealed this decision to the Supreme Court arguing that under Articles of War enacted in 1920, all offenses committed during peacetime were subject to trial and punishment at any time without limitations. However, Hellard contended that he should have been tried under previous laws which had a two-year statute of limitations for non-capital offenses committed during peace-time. The Supreme Court sided with the government's argument stating that Congress intended to remove any limitation period when it passed new articles in 1920 as they did not include such provisions unlike prior versions. Therefore, even though Hellard's offense occurred before these changes came into effect; since he wasn't apprehended until after their enactment - they applied in his case making him liable for prosecution despite lapse of more than two years from commissioning his crime.

The dissenting opinion in the United States v. Hellard case was not available or recorded. The Supreme Court's decision was per curiam, meaning it was a collective decision by the court and did not feature individual opinions from justices. Therefore, there is no known dissenting opinion for this particular case to summarize.
