[2] He was a representative in the National Assembly for Seine-Inférieure from 2 July 1871 to 7 March 1876, and sat with the Union des Droites parliamentary group.

A critic wrote of him, "M. Raoul Duval has plenty of entrain, of élan, of fire, of repartee, but he lacks the power of continued pursuance of one subject.

He begins with a good and substantial address; he finishes with rolling fire of passionate responses to attacks hurled at him.
