Zu den Maßstäben der verfassungsrechtlichen Beurteilung von Regelungen des deutschen Internationalen Privatrechts

On the Standards of Constitutional Review of Provisions of German Private International Law. – The German Federal Constitutional Court regularly reviews the constitutionality of domestic provisions of private international law and their application by the competent courts. In doing so, it takes into account the special features of this type of legislation that result, for example, from the cross-border dimension of the situations it is supposed to address and from the necessary respect for the validity of foreign legal systems. With regard to the protection of marriage and the family, this applies in particular when determining the scope of protection and the structural principles underlying Article 6(1) and other provisions under the German Basic Law. The level of scrutiny when examining constitutionality is primarily determined on the basis of the principle of proportionality.
