In case you ever need to research the Louisiana Constitution of 1921, here’s a link to an on-line copy, courtesy of the Cornell University Library. If you follow the link and scroll down, you’ll see download options, including PDF.
p.s. For the Louisiana Constitution of 1879, follow this link.
If you ever have the need to research the background of U.S. Fifth Circuit judges, check out Ballotpedia’s page on the U.S. Fifth Circuit. There, you will find links to pages on each judge, which in turn contain links to any online information about that judge.
Ballotpedia also has a Louisiana page, with links to pages on the Louisiana Supreme Court and the Louisiana Courts of Appeal. Those pages, in turn, have links enabling you to drill down to pages on a particular court or a particular justice or judge.
