In 1997, when Oregon became the first U.S. jurisdiction authorizing medical aid in dying (MAID), its law included a requirement that patients be legal residents of the state. Other U.S. jurisdictions legalizing MAID followed Oregon in adopting residency requirements. Recent litigation challenges the legality, as well as the justification, for such requirements. Facing such challenges, Oregon and Vermont eliminated their MAID residency requirements. More states could follow this move, for, in certain circumstances, the U.S. Constitution's privileges and immunities clause protects (...) citizens' right to travel to secure medical care. Policy considerations could also motivate states to reexamine whether such requirements are justified in light of existing evidence of how MAID laws have been applied. (shrink)
