     Struck down state laws requiring indigent people reside in a state for a year before becoming eligible for welfare benefits, on the grounds that the states' purpose was to deter poor people from traveling to states with better benefits and favored people who had paid state tax.

     Invalidated a Missouri law that required a wife obtain the consent of her husband before procuring an abortion; required physicians to preserve the life and health of the fetus ; and prohibited the use of saline amniocentesis as a means of abortion.

141. 1990 Cruzan v. Missouri Department of Health*

146. 2000 Bush v. Gore*

     Ruled in favor of the stay preventing Florida from counting legal ballots where the intent of the voter was considered unclear (e.g., hanging chads).

Answer 3

1. 1803 Marbury v. Madison

2. 1810 Fletcher v. Peck

   Held that Georgia could not violate the US Constitution's Contract Clause (Article I, Section 10, Clause 1) by enacting a law that violates or revokes an established contract.

10. 1833 Barron v. Baltimore
