Petition of the day

Issue: Whether an abortion regulation that is rationally related to the state’s interest in maternal health creates an undue burden and is therefore invalid (a) only when it erects a substantial obstacle to obtaining a pre-viability abortion, as the Fifth and Sixth Circuits held, or (b) when the extent of the burden a law imposes on a woman’s right to abortion outweighs the strength of the state’s justification for the law, as the Ninth Circuit held in the decision below.
