Well legal measures - by implimenting mandatory sentences justice for victims is delivered (and criminals i suppose) because there is a set sentence.
Eg - Bilal Skaf 55 years for rape. His brother 33 or something.---> Inequity due to the difference of sentences for same crime
Mandatory sentences mean equity is restored...and equity is one of the 5 key points in the nature of justice,. (H.rights, equlity, fairness, equity, access)
THe only injustice i can think of is the Van Nguyen case in singapore - mandatory death - the NGOs (like Amnesty Interrnational) and Howard governemnt lobbied singapore for clemency - who basically told them to get stuffed its their right as a sovereign state to do it.
Justice being achieved-
Are human rights being violated?
Is there equity?
Is there fairness?
Is there equality
Is the law accessible?
You need to answer these questions (and how it is being done), and if yes to all/most i suppose justice is being achieved
