The Principle of Systemic Integration in International Law

Oxford University Press has published The Principle of Systemic Integration in International Law by Campbell McLachlan.

Systemic Integration examines the operation and health of a key part of international law’s general operating system by addressing the applicable law question: how can the constantly shifting web of States’ rights and obligations be integrated to produce coherent results in international disputes? Informed by McLachlan’s two decades of scholarly and practical experience since his ground-breaking work for the International Law Commission’s Fragmentation Project in 2005, here now for the first time is the summation of his unprecedentedly broad research into the actual practice of States and international tribunals in managing the interrelation of rules.

The book provides practical guidance for the issue that international lawyers encounter every day: working out which rules of international law are applicable to resolve the dispute before them and how through interpretation they can be fitted together. Given the daunting contemporary challenges that face the international community, the book demonstrates the importance of the essential function of international law: not just as disparate expressions of divergent public goods––the separate political projects of a divided world - but rather as integrated parts of a common endeavour.
