Entitled Towards a global compact for safe, orderly and regular migration: A parliamentary perspective, the 2018 Parliamentary Hearing will contribute to a major debate on migration that will culminate with a United Nations Conference in the last quarter of 2018 (dates and venue to be decided).
The Hearing will allow for a comprehensive parliamentary perspective on key questions of migration and help inform the United Nations negotiations of the Global Compact – a new framework for the practical arrangements that need to be in place globally and nationally to ensure migration is properly managed with due regard for the human rights of migrants and the sovereign rights of States.
The Hearing will build on the input provided by parliamentarians, as a distinct constituency, throughout the official consultative process for the Global Compact. It will follow a half day multi-stakeholder hearing on 21 February with representatives from civil society, the private sector and academia.
