According to Dr. Martin Luther King Jr., a just law is one that uplifts human dignity and matches moral values. An unjust law is one that brings people down, treats them unfairly, or is created without giving the people it affects a say in it. He explains this in his Letter from Birmingham Jail by saying that a just law is rooted in fairness and equal treatment, while an unjust law usually serves the interest of the powerful and harms those with less power.
I think this difference really matters. If people don’t know how to tell the difference, they might support or follow laws that are clearly unfair. This can affect how people live day to day, how they view the government, and how they act in politics. When people realize something is wrong, they are more likely to speak out or push for change. This can be through protests, voting, or joining movements that want justice. Knowing what makes a law just or unjust helps people decide when to follow the law and when to challenge it.
A just law today would be the Americans with Disabilities Act. This law protects people with disabilities and makes sure public places are accessible to everyone. It supports equality and makes life easier for people who are often ignored or excluded.
An unjust law today would be those that criminalize homelessness, like banning people from sleeping in public spaces. These laws punish people for being poor instead of helping them. According to Dr. King, that kind of law is unjust because it does not support human dignity and mainly affects people who don’t have the power to fight back.
