Unser Schiedsrechtsteam hat in den letzten dreißig Jahren eine der führenden Schiedsrechtspraxen der Region aufgebaut und unseren exzellenten Ruf als eine führende Kanzlei in der internationalen Schiedsgerichtsbarkeit stetig ausgebaut. Das Internationale Schiedsrechtsteam von Zeiler Floyd Zadkovich vereint nunmehr Experten in Kontinentaleuropa, London und den USA, und zählt damit zu den internationalen Powerhouses der internationalen Schiedsgerichtsbarkeit. Die herausragenden Leistungen unseres Teams werden nun schon über viele Jahre hinweg regelmäßig in einer Vielzahl von Publikationen ausgezeichnet. Am wichtigsten dabei ist, dass diese laufende Anerkennung gerade auch die Zufriedenheit unserer Mandanten mit der hohen Qualität unserer Arbeit widerspiegelt.

Unsere Partner und Juristen genießen für ihre Tätigkeit als Parteienvertreter in Schiedsverfahren und als Schiedsrichter internationales Ansehen. Zusammen waren sie an über 500 Schiedsverfahren beteiligt und sind mit den geschriebenen und ungeschriebenen Regeln ihres Faches bestens vertraut. Unsere Arbeit vereint die höchsten Standards internationaler Advokatur mit einer strategischen Herangehensweise, Business Sense und einem ergebnisorientierten Ansatz.

Unsere Branchenkenntnis, insbesondere unsere umfassende Expertise im Bereich des Energiewirtschafts-, Schifffahrts-, Bauwirtschafts-, Commodities– und Versicherungssektors, zeichnet uns aus. Wir wissen um die Besonderheiten der Streitlösung in diesen Sektoren und verhelfen unseren Mandanten regelmäßig zu optimalen Ergebnissen. Auch auf unsere Erfolgsbilanz bei der Lösung von Post-M&A- und gesellschaftsrechtlichen Streitigkeiten sind wir stolz. Streitigkeiten im Bereich des geistigen Eigentums und des Wettbewerbsrechts sind bei uns ebenfalls bestens aufgehoben.

Internationale Handelsschiedsgerichtsbarkeit

Die internationale Handelsschiedsgerichtsbarkeit bildet den Kern unserer Schiedsgerichtspraxis. Unsere Juristen arbeiten auf höchstem internationalen Niveau, sind für ihre herausragende Praxis ebenso anerkannt wie für ihre akademischen Leistungen. Wir kennen alle Ecken und Kanten des Schiedsverfahrensrechts.

Jede Streitigkeit ist einzigartig. Egal ob hochkomplex oder ein scheinbarer Standardfall – die Lösung Ihrer Streitigkeit erhält unser volles Engagement und ist bei uns in besten Händen.

Unsere Juristen vertreten regelmäßig in Handelsschiedsverfahren nach allen wichtigen Schiedsregeln (z.B. nach den Regeln der ICC, AAA, LCIA, UNCITRAL, VIAC, DIS, SCC, SCAI, LMAA, SMA, GAFTA, FOSFA, SIAC, MCCI, CIETAC, HKIAC und ACICA) sowie in ad-hoc-Verfahren. Unsere Partner sind auch regelmäßig als Schiedsrichter tätig, so etwa nach den Regeln der ICC, VIAC, SCAI, SCC, LCIA und DIS sowie in ad-hoc-Verfahren. Dieser laufende Perspektivenwechsel zwischen Parteienvertretung und schiedsrichterlicher Entscheidungstätigkeit stärkt unsere Beratungspraxis entscheidend.

Unsere Erfahrung umfasst Schiedsgerichtsverfahren mit Sitz in London, Paris, New York, Singapur, Wien, Den Haag, Doha, Zürich, München, Bukarest, Moskau und vielen mehr. Unser Team vereint umfassende Kenntnisse sowohl des Common Law und Civil Law, als auch des Völkerrechts, und hat Streitigkeiten nach einer Vielzahl von anwendbaren materiellen Rechtsordnungen und – regeln erfolgreich begleitet.

In der oftmals entscheidenden Phase der Schiedsrichterauswahl profitieren unsere Mandanten von unserer fundierten Marktkenntnis und umfassenden persönlichen Erfahrung. Auch unser Wissen über die inneren Abläufe der wichtigsten Schiedsinstitutionen verschafft unseren Mandanten oftmals einen strategischen Vorteil.

Jedes Schiedsverfahren ist einzigartig. Unsere Mandanten schätzen die stets gründliche Aufbereitung von Sachverhalten und Rechtsfragen in jedem einzelnen Fall und unsere strategische Umsicht und Kreativität bei der Entwicklung individueller Fallstrategien. Bei der Fallvorbereitung und -präsentation verbinden wir unser außergewöhnliches anwaltliches Know-how mit dem effizienten Einsatz moderner Technologie.

Investitionsschiedsgerichtsbarkeit & Investitionsschutz

Unser Team hat eine umfangreiche Investitionsschiedsgerichtspraxis in Mittel- und Osteuropa (und darüber hinaus) aufgebaut. Unsere Juristen waren und sind derzeit an hochrangigen Streitigkeiten zwischen Investoren und Staaten beteiligt. Darüber hinaus genießt unser Team die einzigartige Unterstützung des Doyens der Investitionsschiedsgerichtsbarkeit, Prof. Christoph Schreuer, der als Of Counsel für Zeiler Floyd Zadkovich tätig ist.

Unsere Juristen beraten sowohl Staaten als auch Investoren in allen Investitionsschutzfragen im Rahmen bilateraler und multilateraler Investitionsverträge. Unsere Erfahrung umfasst Schiedsverfahren im Rahmen der ICSID-Konvention, einschließlich der Additional Facility Rules, der SCC Rules und der UNCITRAL Rules.

Unser Leistungsspektrum reicht von der allgemeinen Beratung zum völkerrechtlichen Investitionsschutz über die rechtliche Beurteilung von Ansprüchen und Streitigkeiten in der pre-trial Phase bis hin zur erfolgreichen Vertretung von Mandanten vor internationalen Tribunalen. Wir unterstützen unsere Mandanten auch bei der internationalen Vollstreckung von Investitionsschiedssprüchen.

Aufhebungsverfahren

Unsere Juristen unterstützen regelmäßig in Aufhebungsverfahren und anderen Rechtsstreitigkeiten mit Bezug zum Schiedsverfahrensrecht. Wir haben zahlreiche Schiedssprüche erfolgreich angefochten sowie verteidigt, unter anderem vor den Gerichten von England und Wales, verschiedenen Federal und State Courts in den USA sowie vor dem österreichischen Obersten Gerichtshof. Unsere langjährige Erfahrung ermöglicht es uns, die Erfolgsaussichten einer möglichen Anfechtungsklage realistisch einzuschätzen und dadurch nach Erlass des Schiedsspruchs zuverlässige strategische Beratung zu bieten.

Wir unterstützen unsere Mandanten auch bei der Ablehnung von Schiedsrichtern – eine Entscheidung, die niemals leichtfertig getroffen werden sollte, sich jedoch in Ausnahmefällen mitunter als unvermeidlich erweist.

Vollstreckung von Schiedssprüchen und Asset Recovery

Wir unterstützen unsere Mandanten regelmäßig bei der internationalen Vollstreckung von Schiedssprüchen. Unsere Juristen sind regelmäßig mit der Anerkennung und Vollstreckung ausländischer Schiedssprüche in Österreich, England und den USA betraut und koordinieren auch Vollstreckungsverfahren in anderen Teilen der Welt.

Ist ein Schiedsspruch erst einmal erstritten, so folgt auf diesen einen Teil mitunter ein „Vollstreckungs-Epilog“, der langwieriger sein kann als die Erlangung des vollstreckbaren Titels selbst. Wir begleiten unsere Mandanten dabei professionell und ergebnisorientiert, unabhängig davon, ob sie Vollstreckung begehren oder sich dagegen wehren. Neben der eigentlichen Verfahrensführung widmen wir uns auch der Auffindung und Sicherstellung materieller und immaterieller Vermögenswerte.

Selbstverständlich unterstützen wir Sie auch bei der Vollstreckung ausländischer oder nationaler staatlicher Gerichtsurteile.

Nationales Schiedsverfahren

Der Schwerpunkt unserer Tätigkeit liegt sicherlich auf der internationalen Schiedsgerichtsbarkeit. Darüber hinaus vertreten wir aber auch in nationalen Schiedsverfahren mit Sitz in Wien (häufig als ad-hoc-Verfahren, oder aber nach regionalen und nationalen institutionellen Regeln), New York und London.

Vor allem für komplexe innerstaatliche Vertragsbeziehungen oder wo Vertraulichkeit von zentraler Bedeutung ist, bietet ein nationales Schiedsverfahren oftmals eine gute Alternative zur staatlichen Gerichtsbarkeit. Unsere Juristen profitieren bei der Führung nationaler Schiedsverfahren von ihren weitreichenden Kenntnissen der internationalen Schiedsgerichtsbarkeit, einerseits, sowie der nationalen Gerichtspraxis in Österreich, den USA und England, andererseits. Unser Team ist auch für arbeitsrechtliche Schiedsverfahren bestens aufgestellt.
