As a long‑standing partner in the Basel office, Dr. Eisner has built a respected practice at the intersection of corporate, banking and compliance law.Professional Background & CredentialsDr. Eisner studied law at the Universities of Basel and Geneva, earning his licentiate in 1986 and his Doctor of Law (Dr. iur.) in 1990. He holds Swiss bar admission (since 1988) and is fluent in German, English and French.

His work spans mergers & acquisitions, corporate restructurings, shareholder agreements, group governance and corporate financing, with special experience in the banking, life sciences and healthcare sectors. He frequently supports boards and senior management teams on risk management, compliance programme design and contractual strategies that align business objectives with Swiss regulatory expectations.Recent Developments & Publications (Past Year)Over the past year Dr. Eisner has continued to publish practical guidance on regulatory changes affecting Swiss corporate and financial actors. In September 2025 he authored a firm briefing for Lenz Caemmerer explaining the new Swiss law on a transparency register for legal entities (the TJPG), the scope of the new reporting obligations for beneficial owners and the anticipated implementation timeline. That briefing has been used as a reference point for clients preparing governance and compliance changes ahead of the register’s entry into force.In 2026 Dr. Eisner was also featured as the recommended Swiss expert by a leading international legal network for a detailed practice guide on sanctions and contract compliance. That guidance analyses the consequences of the Swiss Federal Supreme Court decision 4A_455/2025 (21 May 2026) for general terms and conditions (GTCs), force majeure and sanctions clauses, and offers a clause bank and checklist to help banks, trustees and corporate counsel update their contract documentation and internal procedures. These recent contributions reflect his continuing focus on converting high‑level doctrinal developments into operational drafting and compliance steps for practitioners.Representative Matters & SectorsDr. Eisner’s practice routinely involves advising banks, trustees, corporate groups and family offices on transactional and governance matters. He has particular strength advising clients in regulated industries — notably banking and life sciences — where corporate decisions must be aligned with prudential, liability and health‑regulatory frameworks. He also regularly assists in cross‑border restructurings, shareholder disputes and organ liability questions where Swiss law and international elements converge.Approach & What Sets Him ApartClients value Dr. Eisner for a pragmatic, risk‑sensitised approach that combines deep doctrinal knowledge with practical drafting and process recommendations. He translates regulatory and case‑law developments into concrete contract wording, compliance checklists and board‑level briefings so that legal solutions are operationally effective. His in‑house banking experience gives him particular credibility when advising banks and financial institutions on the implementation challenges of new rules, such as beneficial‑ownership reporting and sanctions risk management.Why Specialist Corporate Advice Matters In SwitzerlandSwitzerland’s corporate and financial regulatory environment is internationally integrated and subject to rapid legal and supervisory change. Recent developments — including expanded transparency requirements for legal entities and intensified judicial scrutiny of sanctions clauses — demonstrate how corporate risk can migrate from commercial negotiation to regulatory and public law arenas. A specialist corporate lawyer in Switzerland brings the combined skills of transactional drafting, regulatory interpretation and dispute foresight that companies and financial institutions need to manage that risk effectively.Thought Leadership & TrainingBeyond written guidance, Dr. Eisner remains active in professional education and coaching, delivering training on banking law, compliance and directors’ duties to in‑house legal teams and boards. His materials emphasise practical implementation: updating GTCs and onboarding documentation, creating contract registers for priority remediation, and documenting the decision‑making rationale needed for audit and litigation defence. He also maintains an active publishing profile and contributes to firm briefings that explain new Swiss rules in plain language for non‑lawyers.Standing & Professional MembershipsDr. Eisner has been a partner at Lenz Caemmerer since 2001 and is widely recognised within the Basel legal community for his banking and corporate expertise. He serves on the board of STEP Basel (TEP), contributes regularly to legal commentary on banking and medical liability, and continues to mentor younger lawyers within the firm. His long tenure in both advisory and in‑house roles underpins a balanced perspective on the needs of institutional and corporate clients.SummaryDr. Eisner combines more than 30 years of experience with a focused, practice‑oriented approach to corporate law in Switzerland. His recent work — including firm guidance on the new transparency register and expert commentary on sanctions‑related contract risk following the 2026 Supreme Court decision — reinforces his role as a trusted adviser for banks, corporate groups and trustees facing regulatory, governance and transactional challenges. He remains a leading resource for practical, Swiss‑law solutions that align legal certainty with business needs.
