Oral argument will be permitted only in cases designated by the Court of Criminal Appeals. If the Court permits argument in a case, the clerk will notify the parties of the date set for argument. If a case will be submitted without argument, the clerk will notify the parties of the date of submission. The clerk must use all reasonable diligence to notify counsel of settings, but counsel's failure to receive notice will not necessarily prevent argument or submission of the case on the day it is set.
