Can states limit abortion and gender-affirming treatments outside their borders?

Legal experts say so-called bounty hunter bills, including the Missouri measure that would let people sue anyone they suspect of helping a resident get an abortion in another state, are most certainly unconstitutional, with little chance of withstanding legal challenges.

Conservative lawmakers across the U.S. have unleashed a wave of state legislation attempting to restrict access to abortions and to gender-affirming medical care for transgender youth by allowing lawsuits to be filed against anyone who helps them.

But now there’s a new twist in what appears to be a broader Republican strategy: Representatives in multiple states are pushing bills that would attempt to limit what residents can and can’t do even beyond state lines.

Recently in Missouri, a state representative introduced a measure that would let people sue anyone they suspect of helping a resident get an abortion in another state.
