An appeal to the High Court can be filed when the Session Court awards a punishment that is four years or more. This means that if the Session Court imposes a sentence of four years or a longer duration, the convicted individual can approach the High Court for a review of their case.
It is important to note that options 1, 2, and 3 are incorrect because they provide sentencing thresholds that are shorter than the correct answer. Appeals to the High Court may be made for a range of reasons, including challenging the validity of the trial, questioning the correctness of the legal interpretation, or presenting new evidence that could potentially impact the outcome of the case.
