It is not lawful for any political party, any legislation or any national commitment to violate "the basic principles" of "this Basic Law" laid down in Articles 1 and 20. Furthermore, the only way that Articles 1 and 20 can be removed is through Article 146, which requires "a constitution that is adopted by a free decision of the German People". So long as the principles of Articles 1 and 20 are retained, they may be amended (as Article 20 has indeed been amended to establish a 'right of resistance'), but the full protection of the eternity clause does not extend to such amendments.
