The Supreme Court has blocked vital components of the strict antiabortion laws enacted in Texas last year by Gov. Rick Perry. The ruling required facilities to spend millions on hospital-level upgrades, which was seen as more about limiting access than safety, and administering doctors to have “admitting privileges” as local hospitals. The resulting action shuttered all but eight abortion clinics throughout the state. Tuesday’s ruling put a halt to these requirements and could lead to access by the millions of women unable to reach the major cities where the few facilities have remained open.
