Corporate constitutional rights and complaints

We defend companies against state intervention in their constitutionally protected rights – particularly in the context of new legislation and regulatory measures – and develop constitutional litigation strategies at the stage of administrative and judicial proceedings to secure legal protection before the constitutional courts. When all other legal avenues have been pursued, constitutional law often provides the final effective means of safeguarding business freedoms from state interference.

Public sector 

Gleiss Lutz has a proven track record of advising the federal government, states, municipalities and other public sector entities. We combine rigorous legal analysis and a strong, solutionsdriven focus to provide clients with straightforward, practical advice on complex constitutional matters.

Legislature

Even the legislature relies on our expertise, for example when assessing and reviewing draft bills. We provide legal opinions, assist in legislative procedures and regularly represent clients in proceedings before the Federal Constitutional Court and the state constitutional courts.

European law

European law is increasingly shaping the legal systems of EU Member States, presenting complex legal challenges for companies, associations, and the public sector. We have extensive experience in advising on all aspects of European law and help our clients navigate complex regulatory frameworks.
