Mining in space: the role of arbitration in the new frontier

The global space industry represents an extraordinary commercial opportunity, with market valuations projected to surpass USD 1 trillion by 2030. This expansion is being driven by significant capital deployment from both public and private investors, with space resource extraction emerging as one of the sector's most lucrative prospects.

Yet, as commercial actors and governments race to capitalise on this new frontier, they face a legal and regulatory environment that remains largely uncharted and, in critical respects, ill-equipped for modern commercial realities. While existing international treaties provide a foundation, they fall short of addressing the sophisticated legal challenges generated by the sector's rapid commercialisation - particularly around space mining ventures.

In this climate of regulatory ambiguity and groundbreaking commercial enterprise, disputes are inevitable. To safeguard significant capital investments and sustain market momentum, businesses must proactively address the legal complexities inherent in this sector and secure robust mechanisms for dispute resolution. Here, arbitration emerges as the optimal and most flexible forum for resolving commercial disputes arising from space mining operations.

Space mining and the emergence of disputes

The commercial extraction of metals and minerals from outer space presents a transformative opportunity for resource development and revenue generation. While the industry is still in its early stages, pioneering companies, including the Canadian Space Mining Corporation and AstroForge, are aggressively advancing the technologies required to commercialise space mining. In Australia, the Australian Space Agency is partnering with NASA on cutting-edge exploration technologies through the Moon to Mars Initiative, including developing instruments to enhance the exploration of critical minerals.

As commercial appetite for space resource ventures intensifies, so too does the imperative for legal certainty. For investors committing capital to outer space ventures, legal certainty is essential to managing downside risk and unlocking further investment. The principal international instruments governing outer space activities are the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies dated 10 October 1967 (Outer Space Treaty) and the Agreement Governing the Activities of States on the Moon and Other Celestial Bodies dated 5 December 1979 (Moon Agreement). Both were drafted in an era when only nation-states participated in space activities. Consequently, these instruments offer insufficient guidance for private enterprises regarding ownership rights, commercial exploitation and monetisation of outer space assets. Critically, they fail to clarify whether private companies can legally explore, extract, and commercialise outer space resources. They also do notprovide dispute resolution mechanisms for conflicts involving commercial parties or between commercial entities and states that may emerge in space mining operations.

The evolving landscape of international and domestic space law

In response to these regulatory gaps, jurisdictions such as the United States, Luxembourg, Japan and the United Arb Emirates have enacted domestic legislation to regulate space property rights frameworks. For example, the US Commercial Space Launch Competitiveness Act of 2015 grants private entities ownership rights over resources extracted from space. By contrast, Australia has yet to implement a similarly proactive legislative framework, despite its rapidly growing space sector, which currently generates approximately AUD 8 billion in annual economic revenue.

Australia's competitive position is further complicated by its status as a signatory to the Outer Space Treaty, the Moon Agreement and the Artemis Accords. This constellation of commitments creates significant challenges in reconciling conflicting obligations, particularly regarding commercial space mining ventures. For example, the Artemis Accords explicitly support commercial exploitation of space resources, whereas the Moon Agreement mandates that such activities be conducted for the benefit of all countries, reflecting a more collectivist approach. Moreover, Article II of the Outer Space Treaty prohibits national appropriation of outer space, including the Moon and other celestial bodies, by claims of sovereignty.

As the regulatory landscape continues to evolve, Australia's approach to these issues will be critical in determining its competitive position in the future governance and commercialisation of space activities.

The future of space disputes and the role of arbitration

The inconsistent enforcement of international space law, coupled with the commercial uncertainties it generates, highlights the inadequacy of the current legal framework for resolving disputes related to outer space commercial activities, particularly in the space mining sector. This challenge is compounded by limited buy in to key treaties. While the Outer Space Treaty enjoys broad ratification, only 17 countries remain parties to the Moon Agreement - a number that has declined following Saudi Arabia's withdrawal in 2024 to join the Artemis Accords. Furthermore, the misalignment between international frameworks and domestic laws (such as the US Commercial Space Launch Competitiveness Act of 2015) regarding the recognition of private property rights in space, creates additional complexity for commercial operators.

With future space mining disputes virtually certain, international arbitration offers a promising solution to these cross-border commercial challenges.

Arbitrators with specialised industry expertise and deep commercial understanding of the issues in dispute can deliver globally enforceable outcomes for space mining disputes. Beyond its cost-efficiency and procedural flexibility, international arbitration offers the significant advantage of global recognition and enforcement, primarily due to the widely ratified New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958). This extensive enforceability is particularly advantageous in the space mining context, where commercial operators function across multiple jurisdictions and need remedies that transcend national boundaries. Moreover, space mining companies stand to benefit from the ability to enforce their rights through Investor-State arbitration, rather than depending on traditional inter-State dispute resolution mechanisms or diplomatic channels. Article VI of the Outer Space Treaty establishes that States bear international responsibility for activities carried out by both governmental and non-governmental actors, meaning that governments assume the legal and financial liability for the actions of private entities operating in outer space.

While international arbitration is well-positioned to address these commercial challenges, there remains substantial opportunity for further development. The establishment of a dedicated arbitral tribunal for space-related commercial disputes, the creation of a specialised arbitral institution, or the development of a globally applicable rules governing outer space commercial activities would represent significant competitive advantages. Notably, in 2011, the Permanent Court of Arbitration introduced arbitration rules specifically tailored for disputes arising from outer space activities, marking an important market development. The United Nations Office for Outer Space Affairs (UNOOSA) has also established a Working Group on Legal Aspects of Space Resource Activities, which is currently drafting recommended principles for exploration, commercial exploitation and utilisation of space resources. For Australia, proactive engagement in the development and promotion of such mechanisms will be essential to protecting its commercial interests in the rapidly expanding space economy.

A strategic approach to the space economy

As the space economy continues to expand, particularly in high-value sectors such as space mining, existing legal frameworks will require reassessment and further development to support commercial growth. Whilst some jurisdictions have begun implementing domestic regulations to attract investment, countries like Australia face the strategic challenge of aligning their national approach with their international obligations while maintaining commercial competitiveness. In this context, international arbitration offers a practical and commercially effective means of resolving the complex disputes that will inevitably arise in this dynamic and lucrative sector.
