Some governments, including but not limited to the United States, are taking ever more draconian measures to prevent asylum seekers from gaining access to territory and status determination procedures. An unknown number die in the attempt to reach safety. Asylum seekers who are intercepted at sea and even those who succeed in reaching a land border may simply be turned back. If allowed to present a claim, they may face detention, family separation, criminal prosecution, and/or bars to eligibility for refugee status based on their lack of documentation, irregular entry, or other supposed legal fault, such as failure to apply for asylum in another country. In opposing policies that criminalize seeking asylum and in defending individual asylum seekers, attorneys have pointed to Article 31 of the 1951 Convention Relating to the Status of Refugees, which, subject to certain limitations, prohibits states from imposing penalties on refugees on account of their illegal entry or presence.
