SANDERIJN DUQUET – JAN WOUTERS

CYIL 5 ȍ2014Ȏ

A third body of research has challenged the formalism of public international law

altogether. Processual understandings of PIL originated from the New Haven and

New International Legal Process (ILP) Schools. Scholars affiliated with these schools

argue that public international law has transformed so that it should no longer be

understood as having only a limited number of categories and dispose of all ‘labels’.

The New Haven School defines law as a process of decision that is both authoritative

and controlling.

16

The ILP School advocates a legal system that develops in line with

international society’s rapidly expanding values. Therefore, international lawmakers

should follow dynamic procedures to develop new legal standards through reasoned

elaboration of their decisions.

17

Drawing on ‘processualist’ theories, a number of

scholars attempted to rethink the body of public international law and its sources.

18

Others, such as Tamanaha, have even gone further by developing a pragmatic concept

of law. In his opinion, law is ‘whatever people recognize and treat as law through their

social practices’.

19

The three aforementioned approaches to study non-traditional norms at the

international level can be conceptualised by placing them on a spectrum, allowing for

more or less deference to the doctrine of sources. As such, a common characteristic is

their indebtedness to the sources doctrine, which is used as a benchmark throughout.

The present contribution does not propose a final compromise in the debate between

those who argue in favour of a bright line between law and non-law, those arguing

for the existence of a grey zone, and those who value ‘processual’ understandings of

the law. It rather submits that, either way, legal scholarship has an important role to

play in analysing international processes that result in norms that are complied with

by both public and private actors and affect individuals.

2.3 Why should legal scholarship be concerned about non-traditional norms?

A legal approach focuses on constructing a legal understanding of, and on developing

a legal framework for, non-traditional norms. The justification is that, whether formally

accepted as a part of law, a special category of law or plainly as non-law, it cannot be

denied that a strong connection exists between public international law and other

forms of regulation in international society.

Three further considerations reinforce this point. First, the number of non-

traditional norms has grown exponentially compared to traditional international

law. Pauwelyn, Wessel and Wouters present evidence of the fact that the field of

traditional international lawmaking is in a process of stagnation, both quantitatively

(number of treaties) and qualitatively (state consent and approval by parliament more

often than not have become formalities in administrative processes) in favour of
