I received a copy of this letter in one of my cases:
What’s wrong with using the short citation form “id.” when citing the record? As I wrote about here, the Fifth Circuit recently standardized the format for citing electronic official records on appeal to require the short form “ROA” followed by volume and page. The court made this change after acquiring the internal ability to generate hyperlinks to the record when uniformly cited, allowing judges ready access to pages they may find important. While the prescribed “ROA” cite tells the program where to go, “id.” apparently does not.
The approved format for citing the record in the Fifth Circuit is available in Appendix Form 7 to the court’s local rules and internal operating procedures, as published with the Federal Rules of Appellate Procedure effective December 1, 2014.
