Defense's incompetence and disregard for procedures is usually grounds for denial of appeal.
" Your Honor, I did not do my job and expressed contempt for the bench, thus I am filing an appeal of your decision." In law this seldom works.
Such behavior by the defendant is indicative of incompetence and disregard of procedure.
The legal system functions on the belief of absolute fairness and adherence to a format that is followed to the letter by by both parties. Breaching these principles is never good and usually has negative consequences. I suppose they did not teach you that in elementary school.
