In 1848, a revolution in France abolished the July Monarchy and led to the creation of the Second Republic, and with it Grévy was appointed Commissioner of the Republic for the department of Jura. In April 1848 he was elected by that department for a seat in the constituent National Assembly. On the signed declaration for his candidacy, Grévy demanded a "strong and liberal Republic, that makes itself loved for its wisdom and moderation, that attracts and pardons all parties...". Foreseeing the rise of Louis-Napoléon Bonaparte in that years' presidential election he began to advocate a weak executive, and became famous during the debates on the drafting of the Constitution for his opposition to electing the president by universal suffrage, instead proposing that the executive power should be vested on a "President of the Council of Ministers", who was to be appointed and dismissed by the directly elected National Assembly. The "Grévy Amendment", as it became known, was dismissed, and in December 1848 Bonaparte was elected president of France.
