criminal matters,

HAVE AGREED as follows:

Article I

Scope of the Treaty

1. The Parties shall co-operate with each other by taking all appropriate

measures that they have legal authority to take, in order to provide mutual

assistance in criminal matters, in accordance with the terms of this Treaty

and subject to the limitations of their respective domestic legal provisions.

Such assistance shall deal with the prevention, investigation and prosecution

of offences or any other criminal proceedings arising from acts which are

within the competence or jurisdiction of the Requesting Party at the time the

assistance is requested, and in connection with ancillary proceedings of any

other kind related to the criminal matters in question.

2. This Treaty does not empower one Party's authorities to undertake, in the

territorial jurisdiction of the other, the exercise and performance of the

functions or authority exclusively entrusted to the authorities of the other

Party by its national laws or regulations.

3. Criminal matters for the purpose of paragraph 1 mean, for Canada,

investigations or proceedings relating to any offence created by a law of

Parliament or by the legislature of a province and, for the United Mexican

States, investigations or proceedings relating to any offence under federal or

state law.

4. Criminal matters shall also include investigations or proceedings relating to

offences concerning taxation, duties, customs and international transfer of

capital or payments.

e. delivery of property, including lending of exhibits;

f. making detained persons and others available to give evidence or

assist investigations;

persons; and

h. other assistance consistent with the objects of this Treaty, which is not

inconsistent with the law of the Requested Party.

Article II

Refusal or Postponement of Assistance

1. Assistance may be refused if, in the opinion of the Requested Party:

public order or similar essential public interest, prejudice the safety of

any person or be unreasonable on other grounds;

b. the execution of the request would require the Requested Party to

exceed its legal authority or would otherwise be prohibited by the legal

provisions in force in the Requested Party, in which case the Co-

ordinating Authorities referred to in Article XII of this Treaty shall

consult with each other to identify lawful means for securing

assistance; or

c. there is a possibility of the death penalty being imposed or executed in

the proceedings in respect of which assistance is sought.

2. Assistance may be postponed by the Requested Party on the ground that the

immediate granting of the assistance may interfere with an ongoing

investigation or proceeding.

3. Before refusing to grant a request for assistance or before postponing the

assistance may be granted subject to such conditions as it deems necessary.

If the Requesting Party accepts assistance subject to these conditions, it shall

not to comply in whole or in part with a request for assistance, or to postpone

execution, and shall give reasons for that decision.

of the Requested Party, the Requesting Party shall hold that person in custody

other than the proceeding to which the request relates.
