O REI · 2026Our manifesto
O REI was not built to be bigger. It was built to be better.
For us, the founders of O REI, there are two pillars of success for an academic programme: the students and the lecturers. Everything else is consequence.
Guiding principles
Governance. Leadership. Ethics.
Governance
A deep working knowledge of the management systems and legal structures that govern world sport · from regulatory frameworks to organisational dynamics and the high-stakes decision-making that shapes the industry.
Leadership
Sports lawyers and managers are leaders by trade. Through interactive learning, mentorship, and real-world scenarios, our students graduate as visionary practitioners ready to drive change in the sports legal arena.
Ethics
Integrity is not a course · it is the foundation. Every decision, every negotiation, every case is studied through the lens of conduct, accountability, and the rules that protect the integrity of sport itself.
