As per case facts, the Respondent, a Junior Telecom Officer, was accused of demanding illegal gratification. A charge sheet was filed, and the Special Judge took cognizance. During trial, the ... sanction for prosecution was deemed invalid, leading to the Respondent's discharge without a finding on the merits of the case. A fresh charge sheet was filed after obtaining a new sanction, which the Respondent challenged, leading to this appeal. The question arose whether a fresh trial is permissible when a previous proceeding was terminated due to an invalid sanction, specifically in light of Section 300 of the Code and principles of double jeopardy. Finally, the Supreme Court clarified that a trial concluded due to an invalid sanction is a nullity, not an acquittal, and therefore, a fresh trial with proper sanction is permissible. However, considering the long delay and the right to a speedy trial, the Court directed the trial court to dispose of the matter within six months, with the cooperation of the Respondent, failing which the Respondent could approach the High Court again.
