Looks like the ACCA website has been redesigned and reorganized. They now have a page for summary affirmances and a “Appellate Library,” and it looks as if this is where briefs will be found. ACCA had earlier announced it would do this. They now list “short form affirmances” in a separate list (in the past we have had to assume a summary affirmance on cases with no written opinion). The NMCCA and AFCCA post summary affirmances along with all other decisions.
The CGCCA posts appellate briefs: https://www.uscg.mil/Resources/Legal/Court-of-Criminal-Appeals/Court-of-Criminal-Appeals-Appellate-Briefs/
The CAAF posts appellate briefs of cases in which there is a grant and oral argument.
If find access to the briefs helpful as a trial practitioner and appellate advocate.
