The Attorney General enjoys broad authority to certify to himself and review de novo decisions of the Board of Immigration Appeals (BIA). Though sparingly used, the certification power is controversial, in part because it permits the Attorney General to announce new rules and overturn longstanding precedent without meaningful process. Under current regulations, the Attorney General is not required to provide even basic procedural protections in certified cases, and he has issued decisions without giving the parties notice of the issues under review or an opportunity for briefing. This Note argues that review of BIA decisions without meaningful procedural safeguards implicates serious due process concerns, raises questions about the quality and accuracy of Attorney General decisions, and undermines the legitimacy and acceptability of immigration adjudication. To address these concerns, this Note proposes that the Attorney General promulgate regulations that require meaningful, adversarial participation by the parties and provide a transparent means of soliciting input from interested amici on issues of broad significance.
