Notjustyet:
Here is what the "Shepherd The Flock" book says about a secondary appeal (p.107, para. 14-15):
"When the disfellowshipping is upheld [by the Appeals Committee], there is no further arrangement for appeal. However, if an individual persists in believing a serious error in judgment has occurred, the appeal committee should inform him that he may submit his allegations in writing to the appeal committee within seven days for transmittal to the branch office. The appeal committee should not mention this provision unless the individual indicates that he believes a serious error in judgment has occurred.
If he indicates a desire to submit a letter of appeal to the branch office, the announcement of disfellowshipping should be delayed. The appeal committee should submit the wrongdoer's letter, the report from the judicial committee, and a report from the appeal committee to the branch office. No announcement should be made until a reply is received from the branch office."
