The patent dishonesty of litigants has always been a real threat in the pathway of delivery of Justice.
Selfish litigants in order to serve their greed, lust often take recourse to tactical falsehood and often mix it with truth or present it to showcase the falsehood as truth in the court of law.
Such acts are being perpetrated with professional skill in a planned way.
This approach has become part of social behaviour. In order to serve self-hood  and in the name of self defence it has become the traditional approach of the society to coverup truth, to cook up truth, to present cooked or mixed truth.
This makes the work of a judge very risky and breeds risk at different stages of judicial proceedings. Quite a few fall a prey to these evil designs.
In order to minimise these risks certain codified norms have been adopted by the courts and the courts try to evaluate as per those predetermined norms and conduct the proceeding through a pre-defined procedure.
These are risk management tools of the justicedelivery system.
For example the courts insist on promptness in stating  the claim to the proper authority to manage the risk of additions, interpolations, development in the statement that makes the details of facts.
The courts insist that these should be written down immediately, once again a tool to manage the risk of resorting to cooked up story or the risk of ommitting the true statement of fact.
