Hercule de Serre supported the
Bourbon Restoration, and was appointed First President of the Court of Colmar in January 1815. He accompanied King
Louis XVIII to
Ghent during the
Hundred Days (March–July 1815) when Napoleon returned from exile. On 15 August 1815 he was elected deputy for
Haut-Rhin. He sat with the majority, supporting the government. He proposed, unsuccessfully, an amendment to the draft law on suspension of individual liberty. He defended General
André Masséna against a petition demanding action against him. He also opposed the conclusions of the report of Kergolay on the return of unsold goods to the clergy. He was closely aligned with the views of
Pierre Paul Royer-Collard. De Serre was reelected on 4 October 1816 and on 20 September 1817. He sat with the majority, and in January 1817 was elected President of the Chamber of Deputies, replacing
Étienne-Denis Pasquier. He held this position until the end of 1818, when he was replaced by
Auguste Ravez. He tended to favor direct elections, but opposed the requirement to reelect members appointed to permanent offices, and approved the suspension of individual liberty. As Speaker, he proposed a new regulation of severe penalties for interruptions. ==Minister of Justice==
