The New Recipe for a General Principle of Law: Premise Theory to “Fill in the Gaps”

Abstract

Abstract This article proposes a new theory, “premise theory”, to account for recent international criminal courts’ practice on finding general principles of law. After analysing the traditional theory of transposition from national to international legal settings, and the modification/choice model, this article demonstrates that the focus should be shifted from arbitrariness to the determinants of results of recognizing general principles of law. Premise theory explains a mechanism that judges modify a common legal principle or choose the most appropriate national legal principle to apply to the issue at hand to reflect the premises of the legal field, the court, and, sometimes, even the individual case. This article concludes with a proposal for utilizing premise theory as an explanatory tool and as a guide for legal reasoning to increase judicial transparency and predictability. Lastly, it advocates for the application of premise theory to other areas of international law.
