@artaa,
I would think that Justice :
- if there is a dispute between two parties - is Fair
- if there is an infringement - then punishment to the accepted norm of society (note - the accepted norm would provide equal/comparable/fair punishments - but as many cases simply aren't comparable - the accepted norm would be the starting place).
Justice by it's very nature, is subjective. It is not objective. Attempting to make it objective is why the Law can be viewed at times as so unjust.
As an example : 'set' fines are very biased towards the rich (as it is much less of a punishment for them, than it is for the poor). A $200 fine could be 2 months spare cash (after living expenses) for a poor person, and be an hours spare cash (after living expenses) for a rich person. Punishing the poor effectively 2 months labor and the rich to just 1 hour is unjust.....and yet if you made the Fine a %/income based fine - then punishing one person $200 for (lets go traffic) speeding 10 over, and another person $5000 for speeding 10 over, is also unjust....ie - justice is screwed either way, and is not a perfect system.
