Here is a link to an order granting rehearing en banc in Reproductive Health Services v. Parson, which involves the constitutionality of Missouri’s ban on Down syndrome abortions. The ban was struck down last month but the full Eighth Circuit, in a sua sponte order, has now granted rehearing en banc.
The federal courts are divided on the constitutionality of such statutes. The issue will likely not be finally resolved until after the Supreme Court decides the Dobbs case next Term.
