At the end of 2015, we published a blog on the principle of autonomy with regard to documentary credits.
Key considerations
A sales contract may be the basis from which a documentary credit is generated, but it is entirely separate and should never form part of the documentary credit.
A documentary credit has its own terms and conditions which do not rely upon the terms or performance of the sales contract. This is the principle of autonomy and relates to a documentary credit being treated as an independent transaction. The autonomy of a documentary credit has been re-confirmed in law many times over the years.
A recent UK court case re-affirmed that principle of autonomy under English law with respect to documentary credits - Petrosaudi Oil Services (Venezuela) Ltd v Novo Banco SA and others.
In essence, the decision clarified that an obligation to pay under a documentary credit will not be easily avoided by reference to provisions of the governing law of the underlying contract.
