Technical grounds for overturning a conviction primarily deal with which aspect?

The correct answer deals with the legal procedures that govern a trial and the processes leading to a conviction. Technical grounds for overturning a conviction often involve examining whether the legal procedures followed were appropriate and adhered to established laws. This can include considerations such as violations of the defendant's rights, miscarriages of justice, or improper conduct during the trial. If legal procedures were not properly followed, it can be grounds for appeal or overturning the conviction, regardless of the actual facts of the case or the evidence presented.

New testimonies and witness credibility are more related to the factual evidence of a case rather than the technical legal processes that determine how that evidence is handled. Public opinion does not have a bearing on the legal framework; it is a societal perspective that does not affect the legitimacy of the legal procedures in a courtroom. Thus, focusing on the adherence to legal procedures is essential for understanding technical grounds for challenging a conviction.
