Keep | Thinking

Rohnke Winter keep thinking. As barristers at the Supreme Court, we complete the work that has been begun by our colleagues before the trial courts.

If the client was successful before the Court of Appeals, we defend the judgement against the opponent’s attacks. We do not simply repeat the reasoning of the court but reinforce it with additional arguments. We critically examine negative judgements. On Appeal, we throw into sharp relief any procedural or substantive errors of law. If the Court of Appeals has not granted leave to appeal to the Supreme Court, we aim to convince the Supreme Court of the importance of the case and the need to correct the lower court’s judgement.

While strongly advocating our client’s case in litigation, we offer a clear and detailed assessment of chances and risks during internal discussions.

Thinking | Across

Rohnke Winter think across boundaries, across all fields of civil and commercial law. In founding our law firm, it was our core objective to offer high quality legal services in this broad field. Our legal specializations and personal experiences are complementary: Christian Rohnke offers the experience and knowledge gained in many years as a partner of a major international law firm, and Thomas Winter supplies the know-how of appellate litigation practice dating back to 2003.

The scope of our work is evident in the cases we have successfully litigated for our clients. Opinions of third parties show the appreciation of our thinking.

Rohnke Winter think things through. We focus our pleadings on the issues that are relevant before the Supreme Court and resolve them in depth and detail using case law and academic writings. Our arguments are based not merely on our legal experience. We understand the underlying business interests, technological background and industry-specific features of our cases.

Where no Supreme Court precedentexists, we develop creative and well-founded solutions. We are always guided by the principle that complex thinking has to be expressed in a clear and lucid manner.
