 The dispute over who succeeds the governor in case of his death would not be solved until the office of Lieutenant Governor was created in a new constitution in 1845.As governor, Dupré oversaw the incorporation of the first railroad, a canal company, a bayou improvement company, the Merchants Insurance Company of New Orleans, and a company to granulate sugar by a new process.During his administration there was also a prohibition of further immigration of free persons of color into the state and the expulsion of all those who entered since 1825.
