Vienna Declaration and Programme of Action
The Convention follows the civil law tradition, with a preamble, in which the principle that "all human rights are universal, indivisible, interdependent and interrelated "of the Vienna Declaration and Programme of Action is cited. The 25-subsection preamble explicitly mentions sustainable development, notes that "disability" is an "evolving concept" involving interaction between impairments and environmental factors, and mentions the importance of a "gender perspective". The preamble is followed by 50 articles. Unlike many UN covenants and conventions, it is not formally divided into parts.
