Justice is an act of just measure. If you are being punished but is unfairly accused, tried or administered, then by definition it is not justice.
If the accused party is released without punishment than no just act has occurred, once again, no justice.
However, if you are guilty of an act where justice has been met and administered...deal with it.
That being said, the majority of court cases in north america have nothing to do with justice, they are usually all about business.
