How can we punish bribe givers as abettor if they can save them by becoming witness against taker?see detail?

Question

Suppose SOME people give bribe to SOME public servant on his demand, for their personal benefits.
( NOT TALKING ABOUT people who help A.C.B. ; by giving bribe to get corrupt officer caught RED HANDED).
4 years later that public servant's peon who was present at that incident complains about it to ACB.
Can all those people who gave bribe SAVE themselves now, from charges as abettors (section 12 ,prevention of corruption act 1988).........
by becoming witness AGAINST that public servant under section 24 of the same act?
Does it mean that there is no harm to SOME bribe giver on demand of the accepter;.......if he gives statement against the accepter?

question from INDIA.

Answer 1

seems to me that an appropriate punishment would be for bribe givers to be cut off from all government business at every level for the length of time they tried to get away with it [four years in your example].

The neat bit is that this would be an administrative action and thus wouldn't be 'doubel jeapordy' under the laws prohibiting someone from being tried twice fo rthe same offense. [One having been forgiven to obtain testimony.]

What ya think?
