Sebastian advises national and international clients on the resolution of disputes in arbitration and state court proceedings.

He specializes in arbitration proceedings in accordance with the ICC, DIS and VIAC Rules.

His professional focus is on providing legal advice in complex post-M&A and shareholders' disputes, in which he can particularly make use of his many years of experience as an M&A lawyer.

In addition, Sebastian advises his clients in disputes relating to major construction projects, manager liability cases and in other commercial disputes.

He also has extensive experience in advising clients on M&A transactions and corporate law matters.

Before joining Orrick, Sebastian worked in the Munich office of a renowned German law firm and in the Toronto office of a major Canadian law firm.

  • Sebastian characterizes his work as follows:

    "Any dispute can be traced back to the fact that the parties involved take differing views about one and the same isse. My task as a lawyer is to understand and analyze my client's point of view and to convince the court that the stance taken up by my client on the issue in dispute is the only conceivable one. This can only succeed, if I (as a litigator) consider a legal brief not only as a technical tool, but rather as a literary work of art that captivates with its logic, form and consistency, both in terms of content and outward appearance. This is the challenge I stand up to day after day."
