QUESTIONS PRESENTED Did the Fifth Circuit err in denying a certificate of appealability on a double jeopardy claim reasoning that I am procedurally barred when a debate exists between the federal judges on this issue (i.e. the district court found I am not barred while a circuit judge, sua sponte, denied the COA overturning the district court, and another circuit judge dissented agreeing with the district court that I am not barred)? Did the Fifth Circuit err in denying a certificate of appealability on the claims addressing: double jeopardy, a non-unanimous verdict, due process violations, and ineffective assistance of counsel?
