The Missouri Compromise was nullified by the new Compromise of 1850 - caused by the admission of California, which extended a long way on either side of the Missouri line, and rendered it obsolete.
The kansas nebraska act ;)
No. The effect of the Kansas-Nebraska Act (1854) was to supersede (nullify) the Missouri Compromise, rendering it inapplicable to future states. The geographical division was not applied, but rather "popular sovereignty" within a state would decide the issue of slavery there. This resulted in internecine warfare in the states of Kansas and Missouri, and murderous attacks by both sides (abolitionists and pro-slavery).The Missouri Compromise (1820) was never actually repealed per se.
Missouri Compromise
why was the Missouri compromise written?
The Missouri Compromise was passed in 1820.
Dred Scott decision
The Missouri Compromise was effectively nullified by the Supreme Court's decision in the 1857 case of Dred Scott v. Sandford. The Court ruled that Congress lacked the authority to prohibit slavery in the territories, declaring the Missouri Compromise unconstitutional. This decision intensified sectional tensions and contributed to the rise of the anti-slavery movement, ultimately leading to the Civil War.
Missouri Compromise
The Dred Scott Case completely nullified the Missouri Compromise. It ruled that slavery was protected under the 5th Amendment because slaves were property. The verdict was that slavery could not be outlawed in any territory.

compromise of 1850
The Act served to repeal the Missouri Compromise of 1820 which prohibited slavery north of latitude 36°30´.
The Dred Scott decision repealed the Missouri Compromise because it was said to deny a man's right to property and that it is unconstitutional. The decision legalized slavery everywhere, and the Missouri Compromise said that there equal free states and slave states, and so now all states are slave states.
The North was upset because the decision declared the Missouri Compromise to be unconstitutional. - Novanet
The Missouri Compromise was not a permanent solution to the problem of slavery in the U.S. While it temporarily resolved tensions by admitting Missouri as a slave state and Maine as a free state, and establishing a boundary for slavery in the Louisiana Territory, it ultimately failed to address the underlying issues of sectionalism and the moral debates surrounding slavery. The compromise was effectively nullified by subsequent events, such as the Kansas-Nebraska Act and the Dred Scott decision, which reignited conflicts and led to increased polarization between the North and South.
There was not a major decision that led to it but there were many that led to it such as the dred Scott decision and the Missouri compromise and the compromise of 1850 and the Lincoln- Douglas debate
