Re-elected in the department of Basses-Pyrénées, Tixier-Vignancour served as a "Non-Inscrit" ("non-attached member") in the National Assembly between January 1956 and December 1958, where he allied himself with the Poujadists. Following the May 1958 crisis and the return of Charles de Gaulle to power, he refused to vote a law that would temporarily authorize the president to revise the constitution until a referendum occurs on a new one. Tixier-Vignancour declared ironically in parliament: "I would never have thought that, twice in my life, I will be asked to delegate the fraction of constituting power I held, and—even better—never would I have imagined that, for the second time, the man who asks for it will be the very same man who punished me for having delegated this power a first time." The Fifth Republic was eventually established on 4 October 1958, approved by 82% of the French in September. On 30 November 1958, Tixier-Vignancour lost his siege to a Radical candidate in the first legislative elections of the new regime. After the dissolution of Jeune Nation by official decree earlier that year, he wrote articles for the group's magazine, launched on 5 July 1958 as an attempt to revive the banned movement.
