What does the harmless error rule state regarding appeals?

The harmless error rule states that not all errors that occur during a trial affect the outcome significantly enough to warrant an appeal. Specifically, this rule allows for the possibility that certain errors, even if they were made regarding the introduction of evidence or other procedural matters, may not have influenced the final verdict. Therefore, if it can be shown that the error did not affect the jury's decision or the rights of the defendant, a court may uphold the original ruling despite the presence of the error.

This concept is crucial in the justice system, as it helps to ensure that the appeals process is not overwhelmed by technicalities and can focus on significant issues that genuinely impact the fairness and integrity of the trial process.
