Abstract: This article examines constitutional innovation through the case study of the emergence of animal protection in Egypt's 2014 Constitution. Egypt's provision, which is a state obligation to provide al-rifq bi-l-hayawan (kindness to animals), was adopted in Article 45 as part of the country's second constitution following the 2011 revolution that ousted President Hosni Mubarak. Three aspects proved crucial to the adoption of the provision: a decision by animal protection activists to influence the constitutional process; the ability of citizens to convey their ideas to the constitutional drafters, albeit in a limited way; and, most importantly, the use of frame bridging. The activists and then the constitutional drafters presented the new cause of constitutional animal protection in terms of well-established areas of social, and constitutional, concern in the country, including Islamic law, women's rights, human rights, and the protection of the environment.
