Which things were declared unconstitutional by the judicial branch?
You seem to under the misapprehension that the opinions of courts make something constitutional or unconstitutional. No. It's the text of the constitution that makes it so. For example, Obergefell v. Hodges did not make it unconstitutional for the states to deny equal protection of the law to gay couples; it became unconstitutional long ago, when Amendment XIV took effect. If some future right-wing court undoes the Obergefell decision, it will still be unconstitutional and illegal for the states to deny equal protection.
