For bail pending appeal to be granted, there must be prospects of success on appeal. Where special circumstances for purposes of avoiding mandatory minimum sentences involve a value judgment by the court, and a different court may reasonably come to a different view, this constitutes sufficient prospects of success to warrant granting bail pending appeal against sentence. A guilty plea tendered by an accused person personally, with confirmation by counsel that it accords with instructions after proper explanation of essential elements, does not constitute a procedural irregularity warranting appeal prospects on conviction.
