Beyond contentious work, we advise our clients in all areas of non-contentious corporate law. This includes the founding of companies, corporate reorganisation, merger and acquisition projects, corporate due diligence, company investigations and the full range of Employment and Industrial Relations matters.

With lawyers licensed in multiple jurisdictions, we assemble specific teams for each project, tailored to the challenges clients face. Where required, we rely on our network of external experts, on matters such as tax or capital market law.

We have acted for clients before various arbitral tribunals and courts, as well as in landmark cases before the Austrian Supreme Court and the Austrian Constitutional Court, and in addition to the Federal and Appellate Courts in the US, and High Court, Commercial Court, and Court of Appeal of England and Wales.

We have managed a variety of corporate disputes, relating to: corporate decisions, shareholder disputes, joint ventures, takeover disputes, squeeze-outs, duties and liabilities of directors and supervisory board members, non-disclosure of market information, partnership disputes, and private foundations disputes. Our firm frequently represents corporations as well as shareholders and managers in such disputes.

When handling these disputes, we build case strategies for each phase of the process. Often such strategies include obtaining or defending preliminary injunctions. An important tool at our disposal, where available.

Our cases range from contractual interpretation disputes through to serious fraud in M&A transactions and its various legal implications. We regularly navigate our clients through representations and warranties issues, and the specific regime on limitation and exclusion of liability underlying the sale and purchase agreement.
