Landmark Supreme Court decisions are really important for shaping how laws work in our country.

These rulings help us understand the Constitution and also set examples that lower courts and lawmakers follow.

For example, the Brown v. Board of Education case in 1954 said that separating students by race in public schools is against the Constitution. This changed the way civil rights laws were made and helped lead to new laws in the future.

Another important case is Roe v. Wade from 1973. This case challenged what society thought and showed how the Supreme Court's decisions can affect laws about personal rights and social issues.

The effects of these big decisions go beyond just legal rules. They often get people talking and can even lead to changes in the Constitution or more court cases.

Each of these important decisions also gets people thinking and debating. They raise questions about judicial power, states' rights, and how we understand the Constitution over time.

So, looking at these cases not only helps us see how laws are made but also shows how law and society change together.
