What was established by Planned Parenthood vs. Casey in 1992 concerning abortion regulations?

The case of Planned Parenthood v. Casey in 1992 reaffirmed the constitutional right to have an abortion established in Roe v. Wade, while also allowing states to regulate abortions. The critical aspect of the ruling was the introduction of the "undue burden" standard, which states that any regulation imposing significant obstacles in the path of a woman seeking an abortion before the fetus attains viability constitutes an undue burden and is thus unconstitutional.

This means that states can impose certain restrictions on abortion as long as those restrictions do not place a substantial obstacle in the way of a woman exercising her right to choose. This ruling balances the state's interest in regulating abortions with a woman's right to make decisions about her own body, ultimately allowing for legislative action without infringing on fundamental rights. Therefore, the allowance of regulations as long as they do not impose an undue burden is a key takeaway from this landmark decision.
