The Q's above is slightly different.
How does a law permits or allows to take different stand in different courts?
Does it have to depend on the nature of the outcome of the case...
In simple words:
It means if the criminal liability is only going to be couple of hundred Rs, but civil liability is going to amount to couple of lakhs for the same matter, then civil matter is to be viewed/investigated very differently. As the criminal liability is very small in such cases, general tendency is to dispose the case as quickly as possible, and nobody would like to have few years long criminal litigation to decide couple of hundred rupees fine. but in civil liability if they were asked to shell-out couple of lakhs rupees, then the court probably don't mind in having a litigation which would continue for few years... and in such cases criminal judgement or guilt plea would have hardly any value in deciding civil liability...
