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

The focus on legal procedures in the context of overturning a conviction is crucial because it addresses the adherence to the rule of law and the rights guaranteed to defendants throughout the judicial process. When examining convictions, courts often consider whether there were procedural errors that occurred during the trial, including issues related to jury selection, evidence admission, or the adequacy of legal representation. These procedural aspects are fundamental, as they ensure that the legal process functions as intended and that the rights of the accused are protected.

In contrast, new testimonies can sometimes lead to a retrial but primarily impact a case's factual basis rather than the legal procedures followed. Public opinion, while it can influence many aspects of a case or its treatment in the media, does not hold weight in the legal process for overturning a conviction, as decisions must be grounded in law rather than societal sentiment. Witness credibility is indeed an important factor in a trial's outcome, but it pertains more to the weight of evidence rather than the procedural integrity that is necessary for a conviction to be deemed lawful. Thus, the focus on legal procedures is key to understanding the technical grounds for challenging a conviction.
