Virginia's Three Government Branches

“The legislative branch makes a law. Which other branch decides if that law follows Virginia's constitution? How does that ensure laws are constitutional? The judicial branch decides that a law does not follow Virginia's constitution. Which other branch made the law in the first place? How does this process make sure laws are constitutional? The executive branch carries out laws. If the judicial branch finds a law unconstitutional, can the executive branch continue to carry it out? Why or why not? How does this ensure laws are constitutional?”
