I quote from National JUdicial Academy Occasional Paper Series No 4 - Risk Management In The Judicial Process by D K Sampath----"A risk context emerges as a consequence of the happening of some events which contribute to such generation of risk. In such cases risk avoidance methods are called for.Some unscrupulous parties may organise the generation of risk situation so that they may exploit the legal system for their private ends. We have already seen how political  pressure or money power twists the lega system to cater to the needs of persons wielding such power. Here a conflict arises between such a person and the system .He emerges out of the conflict with profit.When one party is in power , if elections intervene and the other party comes back to power, these prosecutions are in jeopardy. They may not be left to run their course according to law. The hue and cry is that the system is manipulated to contrive a favourable verdict to the defence. The justification is that there is that there was an initial abuse of the system by the launch of false cases and so what is now done is only rectification. But this is countered by the charge that the manipulation of the trial is wrong, even if it is a false charge.If it is a false case,let it be thrown out.That is the logic.THus,there is an obvious loss of credibility  of the legal system.---------
