Such usages are sometimes called a-national laws. This concept is gaining in popularity due to its potential to destabilize the dichotomy between national and international law.

Article 5 of the UN Convention on the Rights of Persons with Disabilities prohibits all forms of discrimination based on disability. It also guarantees equal protection for persons with disabilities. To ensure that such rights are respected, national laws must recognize and protect them in all aspects of public life. A good example of this is Costa Rica, which has enacted Law No. 7600 on Equality of Persons with Disabilities, which sets out the rights of people with disabilities and sets out clear obligations for public institutions. This law provides legal protection to persons with disabilities and is enforceable in court.
