1. As explained by MLK, the difference between just and un-just law comes down to the morality and purpose of the law. Laws which are arbitrary, exist primarily as a means of retribution, or are otherwise out of line with the commonly accepted moral code are considered unjust. Those laws which seek to protect people, or uplift them would be considered just.
2. Understanding that there are just and unjust laws existing at the same time within our legal code is tremendously important. The distinction between the two, and being able to actively campaign (either through disobedience or the law) against unjust laws has been central to essentially all human development. But, there is also that tension. It absolutely makes a difference in the way we live our lives. For one thing, to deny the difference between the two, and merely claim that “we live in a nation of laws,” without actually considering how that might be wrong, is essentially the end-result of the Southern Strategy. It was a very successful mindworm.
3. An example of an unjust law would be any mandatory sentencing guidelines, or any such 3 Strike policy. It’s great that these have become less popular in recent years, but the damage they caused is immeasurable. These are unjust because they exist solely to punish, but without any of the supposedly rehabilitative aims of incarceration.
To take a very local example of a Just Law, it is the law in New York City that anyone within it have access to shelter 24 Hours a day, 365 days a year. Obviously there are a lot of ways this shakes out, and certainly the overall system is shoddy and in need of redevelopment, but it is also why NYC is able to provide the services it does, services which are virtually unheard of in many parts of the country. This law, in the city constitution, was itself the result of a lawsuit. This is a just law because it’s aim is to preserve the humanity and health of people who are usually experiencing a great deal of trouble.
