Here is one takeaway I got from last week’s LSBA Advanced Appellate Practice Seminar: The judges of the court of appeal prefer citation to their own courts’ cases over cases from other Louisiana circuits. So when citing a case for a legal proposition, try to find one from whichever circuit your brief is going to. Cite cases from other circuits only when you can’t find one just as good from within the circuit.
This isn’t surprising. In my observation, Louisiana’s appellate courts have been moving away from jurisprudence constante and toward stare decisis, meaning that they consider their own precedents as binding. I don’t have anything empirical to back this up; just my own observation of anecdotal stuff.
