This chapter introduces the Charter of Human Rights and Principles for the Internet and Ten Internet Rights and Principles (IRP Coalition 2011, 2013). Under the leadership of the Internet Rights and Principles Coalition at the UN Internet Governance Forum, the IRPC Charter is the outcome of a cross-sector collaboration between civil society organizations, human rights experts, scholars, and representatives from the (inter-) governmental and private sector to provide an authoritative, human rights-based legal framework for decisions around internet design, access and use. Essential to this project’s success was an early decision to anchor the work in precursor civil society initiatives and international law. The coalition building strategy that underpins the Charter brought a range of actors together, face-to-face and online, in the spirit of web-enabled collabowriting based on “multistakeholder participation”. A commitment to forging alliances and cooperation across diverse sectors in order to ensure human-centered internet policymaking has been a key factor in the success of the IRPC Charter to articulate a viable framework for rights-based agenda-setting in a policymaking terrain dominated by powerful techno-commercial interests and competing political agendas.
