Article 26 Mutual assistance

The Parties shall afford one another the widest measure of mutual assistance by promptly processing requests from authorities that, in conformity with their domestic laws, have the power to investigate or prosecute criminal offences established in accordance with this Convention.

Mutual legal assistance under paragraph 1 of this article may be refused if the requested Party believes that compliance with the request would undermine its fundamental interests, national sovereignty, national security or ordre public.

Parties shall not invoke bank secrecy as a ground to refuse any co-operation under this chapter. Where its domestic law so requires, a Party may require that a request for co-operation which would involve the lifting of bank secrecy be authorised by either a judge or another judicial authority, including public prosecutors, any of these authorities acting in relation to criminal offences.
