The main idea of Roe v. Wade was that states could not ban all abortions. Before this case was decided, it was legal for states to ban abortion. In this case, the Supreme Court ruled that the right to have an abortion was included in the right to privacy that (it said) was found in the Constitution. The Court ruled that state abortion laws had to balance between this right to privacy and the right of the state to protect fetuses that could potentially become a human life. The Court made it impossible for a state to ban abortion in the first trimester of pregnancy.
