Empowering Inclusion: How the Convention on the Rights of Persons with Disabilities Promotes Accessibility in Public Spaces

Introduction

Accessibility in public spaces is a cornerstone of social inclusion, ensuring that all individuals, regardless of ability, can participate fully in civic life. For persons with disabilities, access to public spaces is not merely a matter of convenience but a fundamental right that enables them to exercise autonomy, engage in community activities, and contribute to society. The United Nations Convention on the Rights of Persons with Disabilities (CRPD), adopted on 13 December 2006 and entering into force on 3 May 2008, represents a landmark international treaty that seeks to protect and promote the rights of persons with disabilities. This article explores how the CRPD advances accessibility in public spaces as a critical aspect of inclusion, delving into its legal framework, implementation mechanisms, and the broader implications for treaty-making and national legal systems. By focusing on the CRPD’s provisions, particularly those related to accessibility, this discussion aims to illuminate the transformative potential of the treaty and the challenges of translating international commitments into tangible outcomes at the national level.

The CRPD is the first comprehensive human rights treaty of the 21st century, marking a paradigm shift in how disability is perceived—from a medical or charity-based model to a human rights-based approach. It recognizes persons with disabilities as equal members of society with inherent dignity and rights. Accessibility, as enshrined in the CRPD, extends beyond physical infrastructure to encompass information, communication, and services in public spaces. This article examines the specific provisions of the CRPD that mandate accessibility, the mechanisms for treaty incorporation into national law (with a focus on monist and dualist approaches), and the relationship between the CRPD and the Vienna Convention on the Law of Treaties (VCLT) of 1969. Additionally, it addresses how these elements can guide other countries in effectively entering into and implementing treaties like the CRPD to foster inclusive societies.

The CRPD and Accessibility in Public Spaces: A Legal Foundation

The CRPD is a groundbreaking instrument comprising 50 articles that cover a wide range of rights and obligations. Accessibility is explicitly addressed as both a general principle and a standalone obligation under the treaty. Article 3 of the CRPD lists accessibility among its core principles, emphasizing that it is essential for the full realization of all human rights and fundamental freedoms for persons with disabilities (United Nations, 2006). This principle underpins the treaty’s overarching goal of promoting inclusion and equality.

More specifically, Article 9 of the CRPD is dedicated to accessibility, mandating that States Parties take appropriate measures to ensure access on an equal basis for persons with disabilities to the physical environment, transportation, information, and communications, including information and communications technologies and systems, and to other facilities and services open or provided to the public, both in urban and rural areas (United Nations, 2006). This article identifies key areas of intervention, such as the removal of obstacles and barriers to accessibility, the development of minimum standards and guidelines for accessibility, and the promotion of universal design in the development of products, environments, programs, and services. Universal design, defined in Article 2 as the design of products and environments to be usable by all people to the greatest extent possible without the need for adaptation, is a critical concept that aligns with the CRPD’s vision of inclusive public spaces (United Nations, 2006).

The CRPD’s focus on accessibility in public spaces is not merely aspirational but imposes clear legal obligations on States Parties. For instance, Article 9(2) requires States to ensure that private entities offering facilities and services to the public take into account accessibility for persons with disabilities, thereby extending the treaty’s reach beyond governmental responsibility to the private sector. Furthermore, the CRPD recognizes the importance of international cooperation under Article 32, encouraging States to share knowledge, resources, and best practices to improve accessibility standards globally (United Nations, 2006).

Recent studies underscore the practical implications of these provisions. For example, research on accessibility in Dutch public spaces highlights how the CRPD framework guides national efforts to adapt urban environments for persons with disabilities through regulations and local actions (MDPI, 2025). Similarly, in Poland, studies on the accessibility of places of worship demonstrate how public entities, including religious institutions, are adapting spaces to comply with CRPD standards (Brill, 2025). These examples illustrate the treaty’s role in catalyzing tangible improvements in accessibility and inclusion at the local level.

Legal Mechanisms for Entering into Treaties under the CRPD Framework

The ability of a country to enter into international treaties like the CRPD is governed by both international law and domestic legal frameworks. Under international law, the capacity to conclude treaties is a fundamental attribute of state sovereignty, as recognized by the Vienna Convention on the Law of Treaties (VCLT) of 1969, which serves as the primary legal framework for treaty-making. Article 6 of the VCLT affirms that every state possesses the capacity to conclude treaties, provided it adheres to the procedural and substantive rules outlined in the convention (United Nations, 1969). The CRPD, while not explicitly addressing the capacity to enter into treaties, operates within this broader international legal context.

At the national level, a country’s ability to enter into treaties is often determined by its constitution or fundamental laws. For the purposes of this discussion, it is assumed that the country in question (referred to generically as “the State”) has constitutional provisions that delegate authority to the executive or legislative branches to negotiate, sign, and ratify international agreements. Such provisions typically align with the principles of the VCLT, ensuring that the State can legally commit to instruments like the CRPD. For example, ratification of the CRPD, as outlined in its Article 43, requires States to express consent to be bound by the treaty through formal procedures, often involving parliamentary approval or executive action, depending on national legal traditions (United Nations, 2006). This process ensures that the State’s commitments under the CRPD are legally binding under international law.

Monist vs. Dualist Approaches to Treaty Incorporation

Once a State enters into a treaty like the CRPD, the process of translating international obligations into national law depends on whether it adopts a monist or dualist approach to international law. In a monist system, international treaties are automatically incorporated into national law upon ratification, without the need for additional legislative action. Such treaties often have direct effect, meaning they can be invoked before domestic courts as part of the legal system. In contrast, a dualist system treats international law and national law as separate spheres, requiring specific domestic legislation to transform treaty obligations into enforceable national law.

Assuming the State under consideration operates under a dualist system—a common approach in many common law jurisdictions—ratification of the CRPD would not automatically render its provisions enforceable domestically. Instead, the State would need to enact specific legislation to align national laws with CRPD obligations, such as accessibility standards for public spaces. This process often involves drafting new laws or amending existing ones to reflect the treaty’s commitments, as seen in countries like the United Kingdom, where domestic legislation such as the Equality Act 2010 was introduced to partially implement CRPD provisions (House of Commons Library, 2025). In dualist systems, the lag between ratification and implementation can pose challenges, as obligations under international law may remain unmet until domestic legislation is enacted.

Conversely, in a monist system, the CRPD’s provisions on accessibility could immediately form part of national law upon ratification, allowing for quicker enforcement. However, even in monist systems, effective implementation often requires supplementary regulations or policies to operationalize treaty commitments. Regardless of the approach, the CRPD’s Article 4 emphasizes the obligation of States Parties to adopt all appropriate legislative, administrative, and other measures to implement the rights recognized in the treaty, underscoring the importance of aligning national frameworks with international standards (United Nations, 2006).

The choice between monist and dualist approaches significantly impacts how swiftly and effectively CRPD obligations, such as accessibility in public spaces, are realized. Dualist systems may face delays due to legislative processes, while monist systems might struggle with practical enforcement if institutional capacities are lacking. Understanding a State’s approach is therefore crucial for assessing its compliance with the CRPD and identifying areas where international cooperation or capacity-building may be needed.

The CRPD and the Vienna Convention on the Law of Treaties (VCLT) 1969

The relationship between the CRPD and the Vienna Convention on the Law of Treaties (VCLT) of 1969 is an important consideration for understanding how States enter into and implement treaties. The VCLT, adopted on 23 May 1969, codifies the rules and principles governing the formation, interpretation, and termination of treaties. It serves as the foundational framework for international treaty law and applies to all treaties concluded between States after its entry into force on 27 January 1980 (United Nations, 1969).

The CRPD, adopted in 2006, falls within the temporal scope of the VCLT, meaning that its formation, interpretation, and application are governed by VCLT principles for States Parties to both instruments. However, it is important to clarify that the CRPD itself is not a “party” to the VCLT, as the VCLT applies to States and, in certain cases, international organizations, not to specific treaties. Rather, the CRPD operates as a treaty under the broader regime established by the VCLT. For States that are parties to both the VCLT and the CRPD, the rules of treaty interpretation (Articles 31-33 of the VCLT), consent to be bound (Articles 11-17), and reservations (Articles 19-23) guide their engagement with the CRPD (United Nations, 1969).

This relationship has significant implications for how other countries might enter into treaties with or similar to the CRPD. The VCLT provides a standardized framework that ensures clarity and predictability in treaty-making. For instance, under Article 11 of the VCLT, States express consent to be bound by a treaty through signature, ratification, acceptance, approval, or accession, a process mirrored in Article 43 of the CRPD (United Nations, 1969; United Nations, 2006). Countries seeking to ratify the CRPD must adhere to these procedural norms to ensure their commitments are legally recognized under international law. Moreover, the VCLT’s rules on reservations allow States to tailor their obligations under the CRPD to align with national priorities or constraints, provided such reservations do not undermine the treaty’s object and purpose (United Nations, 1969).

For countries not party to the VCLT, customary international law—many principles of which are reflected in the VCLT—still governs treaty-making practices. This ensures that even non-parties to the VCLT can engage with the CRPD under internationally accepted norms. The VCLT’s framework thus serves as a model for other countries, promoting consistency and reliability in how States commit to and implement human rights treaties. By adhering to these principles, States can foster trust and cooperation in addressing global challenges like accessibility for persons with disabilities.

Challenges and Opportunities in Implementing CRPD Accessibility Provisions

While the CRPD provides a robust legal framework for accessibility in public spaces, its implementation at the national level often faces significant challenges. One primary obstacle is the lack of resources and infrastructure in many countries to meet accessibility standards. Retrofitting existing public spaces to comply with universal design principles can be prohibitively expensive, particularly for developing nations. Additionally, awareness and technical expertise on accessibility issues may be limited, hindering effective policy design and enforcement.

Legislative gaps also pose a barrier. In dualist systems, the absence of enabling legislation can delay the translation of CRPD commitments into national law, leaving obligations unmet. Even in monist systems, the direct application of international law may not suffice without supporting regulations or guidelines. For example, a recent report on Colombia’s implementation of the CRPD highlights the need to move beyond legal frameworks to real-world impact, emphasizing the importance of enforcement mechanisms and resource allocation (Archive.ph, 2025).

Despite these challenges, the CRPD offers numerous opportunities for advancing accessibility. Its emphasis on international cooperation under Article 32 encourages States to share best practices, technical assistance, and financial resources to overcome implementation barriers (United Nations, 2006). Regional and bilateral partnerships can play a crucial role in this regard, as seen in the European Union’s efforts to harmonize accessibility standards across member states under the CRPD framework (European Commission, n.d.).

Moreover, the CRPD’s monitoring mechanism, established under Article 34, provides a platform for accountability. The Committee on the Rights of Persons with Disabilities, composed of independent experts, reviews periodic reports submitted by States Parties on their implementation progress, offering recommendations to address gaps (United Nations, 2006). Civil society organizations and disabled persons’ organizations (DPOs) also play a vital role in advocating for accessibility, as mandated by Article 4(3), which requires States to involve persons with disabilities in policy development (United Nations, 2006). This participatory approach ensures that accessibility measures reflect the lived experiences and needs of those directly affected.

Broader Implications for Inclusion and Treaty-Making

The CRPD’s promotion of accessibility in public spaces extends beyond immediate physical or technological improvements—it fosters a cultural shift towards inclusion and equality. By mandating accessible environments, the treaty challenges societal attitudes that marginalize persons with disabilities, aligning with its preamble’s recognition of the inherent dignity and worth of all individuals (United Nations, 2006). Public spaces that are accessible not only enable participation but also signal a commitment to diversity and human rights, setting a precedent for other areas of policy-making.

In terms of treaty-making, the CRPD and its interaction with the VCLT provide valuable lessons for other countries. The structured process of consent, ratification, and implementation under the VCLT ensures that commitments to human rights treaties are clear and binding, reducing ambiguity and enhancing compliance. Countries entering into treaties like the CRPD can draw on this framework to strengthen their legal and institutional capacities, ensuring that international obligations translate into meaningful change. Furthermore, the CRPD’s emphasis on accessibility as a cross-cutting principle can inspire similar provisions in other human rights instruments, embedding inclusion as a global norm.

Conclusion

The Convention on the Rights of Persons with Disabilities stands as a pivotal instrument in the global movement towards inclusion, with accessibility in public spaces serving as a critical pillar of its human rights framework. Through provisions like Articles 3, 9, and 32, the CRPD mandates States to create environments where persons with disabilities can participate fully and equally in society. However, the realization of these rights depends on effective incorporation into national law, influenced by whether a State adopts a monist or dualist approach to treaties. The relationship between the CRPD and the Vienna Convention on the Law of Treaties further underscores the importance of structured, legally sound treaty-making processes, offering a model for other countries to follow.

While challenges such as resource constraints and legislative gaps persist, the CRPD’s mechanisms for international cooperation, monitoring, and participation provide pathways to overcome them. By prioritizing accessibility, States not only comply with international obligations but also build societies that value diversity and inclusion. As the global community continues to grapple with inequality, the CRPD serves as both a legal tool and a moral compass, guiding efforts to ensure that no one is left behind in the quest for accessible, inclusive public spaces.
