P 12; (ii) absence of evidence of demand as on November 20, 1974; (iii) absence of any prior arrangement where and when the complainant was to meet the appellant and, therefore, the trap could not be successfully arranged which might permit an inference that the whole story of acceptance of bribe money is concocted; (iv) further two motbirs P.W. 1 Ram Babu and P.W. 2 Keshar Mal were petty clerks specially selected by P.W. 3 Prahlad Narayan; (v) in their evidence they have tried to improve upon the prosecution version which shows their unconcealed interest in the success of the trap which would render them partisan witnesses; (vi) there are certain omissions in the evidence of the prosecution witnesses which may indicate that the defence version of planting the currency notes when the appellant had gone to bath room is probabilised; (vii) that no inference be drawn from the fact that when hands of the appellant were dipped in the sodium carbonate solution it turned pink because admittedly when hands of the accused were caught by the members of the raiding party one or the other of them may have transmitted phenolphthalein powder to the hands of the appellant.
