Judicial review is the ability of the supreme court to decide and examine if a statute, treaty or administrative regulation violates the provision of the existing law written in the state constitution. In the United States, the authority for judicial review has been inferred from the structure, provisions, and history of its Constitution.
Missouri Compromise
The Missouri Compromise split the Louisiana Territory with the North being free from slavery and the South being allowed to have slavery.
The issue of slavery was a rising concern and with each state entering into the Union the balance of slave and free states was skewing. With a new land mass to be concerned with, the government needed a compromise to deal with new states coming into the Union in an effort to maintain slave v. free states. Missouri was entered as a slave state and Maine entered as a free state. The compromise also set the 36'30 line splitting Louisiana Territory. The compromise would last until 1850.
