20. Exaggerated devotion to the rule of benefit of doubt must not nurture fanciful doubts or lingering suspicion and thereby destroy social defence. Justice cannot be made sterile on the plea that it is better to let hundred guilty escape than punish an innocent. Letting guilty escape is not doing justice according to law. [See: Gurbachan Singh v. Satpal Singh and Others [AIR 1990 SC 209]. Prosecution is not required to meet any and every hypothesis put forward by the accused. [See State of U.P. v. Ashok Kumar Srivastava [AIR 1992 SC 840]. A reasonable doubt is not an imaginary, trivial or merely possible doubt, but a fair doubt based upon reason and common sense. It must grow out of the evidence in the case. If a case is proved perfectly, it is argued that it is artificial; if a case has some flaws inevitable because human beings are prone to err, it is argued that it is too imperfect. One wonders whether in the meticulous hypersensitivity to eliminate a rare innocent from being punished, many guilty persons must be allowed to escape. Proof beyond reasonable doubt is a guideline, not a fetish. [See Inder Singh and Anr. v. State (Delhi Admn.) (AIR 1978 SC 1091)]. Vague hunches cannot take place of judicial evaluation. “A judge does not preside over a criminal trial, merely to see that no innocent man is punished. A judge also presides to see that a guilty man does not escape. Both are public duties.” (Per Viscount Simon in Stirland v. Director of Public Prosecution (1944 AC (PC) 315) quoted in State of U.P. v. Anil Singh (AIR 1988 SC 1998). Doubts would be called reasonable if they are free from a zest for abstract speculation. Law cannot afford any favourite other than truth.
