This work analyzes if the principle of systemic integration, as expounded in article 31(3)(c) of the VCLT, contributes to the attainment of a coherent international legal system. For this purpose, it considers three general ideas: (i) the "unity" of the international legal system and fragmentation; (ii) the general rule on treaty interpretation and the principle of systemic integration; and (iii) the role of systemic integration in the achievement of coherence. Each one involves specific issues and considerations which ultimately assist in addressing the main question as to the usefulness of the principle in the curtailment of fragmentation in the international legal system.
