  Comments
  When the 
  
  lower Courts have been convinced 'beyond reasonable doubt’ by the PW’s statement 
  
  that the deceased died because of being fired upon by the accused, the 
  
  conviction by such Courts is not bad in law and the reliance on PW need not be 
  
  proved again [Hare Krishna Singh & Ors. v. State of Bihar; AIR 1988 SC 863].
