Non-refoulement is a principle in international law that prohibits countries from returning refugees or asylum seekers to a place where they may face persecution, torture, or serious harm. This principle is a key part of the 1951 Refugee Convention and aims to protect individuals fleeing danger. Under non-refoulement, states must assess the risks faced by individuals before deporting them. This ensures that those seeking safety are not sent back to situations that could threaten their lives or freedom, reinforcing the commitment to human rights and humanitarian protection globally.
