23- 4- 5- Every State Party shall commit itself to adopting the procedures necessary to fulfill the obligations set forth in Articles 34 to 42. Requests for bilateral assistance and related communications shall be submitted in writing. In case of emergency, a State Party may submit such request in an expeditious manner, including by fax or email, provided such communication ensures a reasonable degree of security and reference (including by using coding) and confirmation of dispatch as required by the State Party. The State Party from which assistance is requested shall respond to the request through a fast means of communication. Except as otherwise stated in this chapter, bilateral assistance shall be subject to the requirements set forth in the law of the State Party from which assistance is requested or in mutual assistance treaties, including the grounds on which the State Party can rely to refuse cooperation. The State Party from which assistance is requested may not exercise its right to refuse assistance with respect to offenses set forth in Chapter II only on the basis that the request relates to an offence that it considers as a financial offence. Whenever the State Party from which assistance is requested may provide such assistance only in the presence of dual criminality, this condition shall be considered fulfilled regardless of whether the laws of the State Party classify the offence in the same category as those of the requesting State Party, provided that the act leading to the offence in respect of which assistance is requested is considered an offence according to the laws of the State Party. Article 33 Circumstantial Information 1- A State Party may – within the confines of its domestic law – and without prior request, give another State information it obtained through its investigations if it considers that the disclosure of such information could help the receiving State 17
