comply with the principles and rules on which it confers a public
policy character, and in case of non-compliance it imposes on its
courts the duty to restore a situation that will be in accordance with
these principles and rules. Similarly, truly international public policy
is a part of international law, the part which even an agreement
between two States may not violate. Can the same be said of
transnational public policy? Is there a legal system, distinct from the
States and from international law, that imposes on its subjects the
duty to respect the principles and rules on which it confers a public
policy character?
2-13 Such a legal system has been said to exist. One of its finders,
or inventors, Professor Berthold Goldman, has given it the name of
lex mercatoria.

Others prefer to call it new law merchant, or
transnational law, although this last expression has also been given
other meanings, notably by Professor Philip Jessup.

Lex
mercatoria would be the legal system spontaneously emerging from
the society of international merchants, the so-called societas
mercatorum: ubi societas, ibi jus. And transnational public policy
would be the part of the lex mercatoria presenting the characters of
public policy.
(8)
2-14 It is important to decide whether transnational public policy is,
or is not, a part of a legal system, because its nature will not be
exactly the same.
2-15 I personally do not believe that a legal system corresponding
to the definition of lex mercatoria exists. Since this is not the time
and place for a demonstration, I shall just mention briefly the main
reason why I think that lex mercatoria may well be the name given to
a set of legal rules, but does not constitute a legal system.
2-16 A legal system is formed not only of rules, but, even more
importantly, of judges and of organs exercising a power of coercion.
Lex mercatoria lacks both. page "64" In particular, contrary to
what has been suggested by some authors,
(9)
arbitrators are not
empowered to adjudicate disputes by the society of merchants and
do not render their awards in the name of that society: they receive
their powers only from the parties in the particular dispute; and only
State courts and State organs of coercion are able to enforce arbitral
awards. It is even doubtful that there is a society of international
merchants; it requires more than doing business together to form a
society.
2-17 Now, even if there was a society of international merchants,
could the principles known as transnational public policy emanate
from that society? This would be surprising, since what these
principles accomplish is mainly to limit the freedom of trade, which is
not what merchants normally wish to do. If we take for instance the
prohibition of the traffic of illicit drugs, there are on the one hand
those who are involved in such trafficking, who do not want it to be
limited, and on the other hand those whose activities are totally
different, who simply do not care; or if they do, it is as ordinary
citizens, not as merchants.
2-18 The prohibition, as an element of transnational public policy,
therefore rests on the common feelings of ordinary citizens,
inscribed in the legislation of a majority of States, and/or in
international treaties drafted and signed by them. That does not
make it part of a legal system which would be distinct both from the
States and from international law.
2-19 What is transnational public policy then? And since it is not a
set of legal principles having a binding force, resting on a legal
system, where does its power to deprive a contract of its binding
