Article 116(2) of the German Basic Law or Section 15 of the Citizenship Act?
Three paths to German citizenship for victims of Nazi persecution and their descendants - and how to find the right one Note: This article is intended to provide general information and does not replace individual legal advice. Naturalisation for restitution concerns complex family and legal-historical contexts that must always be examined on a case-by-case basis. Please consult a lawyer for your specific situation. Your grandfather was a German citizen of Jewish faith. He emigrated to Argentina in 1939. In 1941, he automatically lost his citizenship under the 11th Ordinance to the Reich Citizenship Act. Your father was born in Buenos Aires in 1948, you yourself in 1980. Now you want your German citizenship back - but which law is actually responsible? German law does not have one naturalisation process for restitution, but three different bases for claims: Article 116 Paragraph 2 of the Basic Law (GG), Section 15 of the Citizenship Act (StAG) and Section 5 StAG. Each has its own requirements, its own scope of application and its own legal consequences. If you choose the wrong basis, you risk delays at best - and rejection at worst. Art. 116 para. 2 of the Basic Law - the constitutional right to naturalisation The oldest and best-known provision has been directly in the Basic Law since 1949. Art. 116 para. 2 sentence 1 GG stipulates: Former German citizens who were deprived of their citizenship between 30 January 1933 and 8 May 1945
Reclaiming German Citizenship: Re-naturalisation of former Germans abroad pursuant to Section 13 of the Nationality Act (StAG)
You were born and grew up in Germany. At some point you emigrated - to Canada, the USA, Australia, Brazil. There you took on the citizenship of the new country. What you may not have known at the time is that you lost your German citizenship when you acquired the foreign citizenship. Automatically, by law, without you ever having renounced it. Many people only find out years later. The next time they visit the German embassy. When renewing your passport. Or when their own children ask if they are also German. Section 13 of the Citizenship Act (StAG) opens up a way back for former Germans: re-naturalisation from abroad. We explain here what the procedure requires, what it costs and what it means for your children. Important note: This article is for general guidance and does not replace individual legal advice. Re-naturalisation according to § 13 StAG is a discretionary decision with high requirements. Have your case examined by a lawyer specialising in immigration law. First step: Have you really lost your German citizenship? This sounds like a strange question, but it is a valid one. Not everyone who believes they have lost their German citizenship has actually lost it. Before you apply for re-naturalisation, it is worth checking carefully. No loss has occurred if you
Fixed-term employment contract – when a lawsuit for indefinite employment is worthwhile
Your fixed-term employment contract expires and nobody is talking about extending it. Or worse: you find out three weeks before the end that there will be no further employment. Now you are faced with the question of whether you have to accept this - or whether you can defend yourself against it. The answer depends on whether the fixed term of your employment contract was effective at all. Because many fixed-term contracts are not. And if the fixed term is ineffective, you are entitled under the Part-Time and Fixed-Term Employment Act (TzBfG) to continue to be employed for an indefinite period. You can enforce this claim by filing an action for the cancellation of a fixed term - also known as an action for control of a fixed term. Important note: This article is intended to provide general legal guidance and does not replace individual legal advice. In practice, issues relating to fixed-term contracts are often complex and require an examination of your specific employment contract. Consult a lawyer specialising in labour law for your situation. What is an action for limitation of time? An action for termination is a declaratory action before the labour court. It is not directed against a dismissal, but against the fixed term itself. The aim is for the court to determine that the agreed fixed term was invalid and that the employment relationship continues indefinitely beyond the intended end date. The legal basis for this can be found in Section 17 TzBfG. It states the following: Anyone who wishes to assert that the fixed term of their
