However, the reticence of a federal law to authorize federal prosecution of a particular act committed under federal jurisdiction does not prevent states from passing their own laws against the act committed under their jurisdiction. Meanwhile, the definition of all unborn babies as "members of the species homo sapiens" in section (d) says essentially what proposed "personhood" laws say. Sponsors of such proposals say such legal language will trigger the "collapse" clause in "Roe v. Wade", by establishing what they suggest "Roe" said must be established for legal abortion to end. Several state supreme courts have ruled that sections (a) through (c) are not threatened by Roe, but no court has addressed whether Roe can survive the suggested triggering of its "collapse" clause by section (d).
