He sat in the Chamber of Deputies, of which he served as President from 1905 until 1915. He once again resumed his legislative position in a by-election in 1904, and remained until his death. He was elected President of the Chamber in 1905. His first act was to head the Chamber's deputation to Schloss Hohenburg for the funeral of Grand Duke Adolphe. Laval married Marie-Albertine-Petronille-Therese Metz, daughter of Auguste Metz of the politically influential Metz family.
