Mutual Assistance in Criminal Matters (Republic of Portugal) Regulations

To understand the operation of the regulations, several key concepts defined within the scheduled Treaty must be analysed. These concepts govern the jurisdictional boundaries and procedural limits of mutual assistance.

The first critical concept is the "Central Office." Established under Article 12, each nation must designate a specific administrative body to transmit, receive, and manage all requests for assistance. For Australia, the Central Office is the Attorney-General's Department in Canberra. For the Republic of Portugal, it is the Procuradoria-Geral da República in Lisbon. This centralisation bypasses direct, uncoordinated communication between local police forces or courts, ensuring that all requests are vetted for compliance with domestic laws and treaty obligations before execution.

The second concept is "Dual Criminality," which is treated with a nuanced binary threshold under Article 2. As a general rule, Article 2(1) dictates that mutual assistance may be granted even if the targeted conduct is not an offence under the law of the requested state. However, a strict dual criminality requirement is maintained for requests involving the search and seizure of property. For such intrusive measures, the underlying conduct must constitute an offence under the laws of both Australia and Portugal. Article 2(3) clarifies that in determining dual criminality, the technical categorization or terminology used by either nation is irrelevant: the focus is purely on whether the underlying acts or omissions constitute a crime in both jurisdictions.

The third concept relates to "Fiscal Offences." Article 2(2) explicitly provides that assistance cannot be refused solely because the law of the requested state does not impose the same type of tax, duty, customs, or exchange regulation as the requesting state. Assistance is available if the underlying acts or omissions constitute an offence of the "same nature" under local law. This prevents individuals from using differences in national tax structures or currency regulations to shield themselves from cross-border financial investigations.

Fourth, the "Proceeds of Crime" and "Property Used in the Commission of the Offence" (instruments of crime) are treated as distinct subjects of restraint and forfeiture under Article 10. The Treaty targets not only the direct profits of criminal activity but also the physical assets utilized to facilitate the crime, subjecting both to freezing orders and eventual confiscation.

Finally, the concept of a "Political Offence" acts as a mandatory barrier to assistance under Article 3(1)(a). Although the Treaty does not provide an explicit definition of what constitutes a political offence, the determination is left to the executive discretion of the requested state, allowing it to deny assistance if it believes the prosecution is politically motivated.

The practical operation of the regulations directly impacts several distinct groups of individuals, corporate entities, and public authorities across both jurisdictions.

First, it affects criminal defendants and individuals under active investigation. For these individuals, the regulations determine the extent to which evidence located in the foreign jurisdiction can be gathered and used against them, or conversely, how they might secure exculpatory evidence. The formalization of mutual assistance under this treaty structures the process by which foreign-sourced witness statements, bank records, and physical evidence are integrated into their trials.

Second, the regulations impact witnesses and experts. Under Article 7, ordinary citizens who are requested to provide testimony or act as experts may be summoned. The treaty distinguishes between those who provide evidence within their home territory and those who are requested to travel to the territory of the requesting state. Crucially, the regulations protect these individuals by ensuring that their consent is required before they can be transferred to testify abroad, and by shielding them from domestic penalties or coercive measures if they refuse to give such consent.

Third, the regulations affect individuals in custody. Article 8 establishes the mechanism by which a person currently serving a prison sentence in one country may be transferred in custody to the other country to give evidence. The rights and physical custody of these individuals are heavily regulated during the transfer period, requiring their explicit consent and ensuring they are returned to their home jurisdiction to complete their sentences once their presence is no longer required.

Fourth, third-party asset holders, particularly financial institutions, corporate entities, and joint-venture partners, are significantly affected. Under Article 10, when either state seeks to locate, freeze, or confiscate the proceeds of crime, domestic banks and financial intermediaries in the other state must identify and restrain the assets in question. Article 10(5) explicitly states that the rights of bona fide third parties must be respected under the law of the requested state, meaning that innocent co-owners, lenders, or commercial partners must navigate local legal systems to protect their stakes in targeted property.

Finally, the regulations govern the operations of public officials, specifically officers within the Australian Attorney-General's Department, prosecutors from the Commonwealth Director of Public Prosecutions, police officers, and their administrative and judicial counterparts in Portugal.

The scheduled Treaty balances the sovereign rights of the state parties with the procedural rights and immunities of individual participants.

For the state parties, there is a fundamental duty under Article 1 to grant each other the widest measure of mutual assistance in criminal matters. However, this duty is paired with a comprehensive right of refusal under Article 3. A requested state is legally obligated to refuse assistance if it determines that the request relates to a political offence, threatens its sovereignty, security, public order (ordre public), or other essential interests, or is suspected to be a pretext for prosecuting an individual based on race, sex, religion, nationality, or political opinions. Under Article 3(2), a discretionary right of refusal also exists if the requested state considers that other substantial grounds make the assistance "unreasonable." If a state decides to refuse a request, it has a duty under Article 3(4) to promptly inform the requesting state of its decision and the underlying reasons.

Witnesses and experts who agree to assist are granted substantial rights and immunities, designed to incentivize cooperation. Under Article 9(1), any person who travels to the requesting state pursuant to a request for assistance is granted "safe conduct." They cannot be detained, prosecuted, or punished, nor can they be subjected to civil suits in that territory, for any act or omission that occurred before their departure from the requested state. Furthermore, they cannot be forced to give evidence in any proceeding other than the one specified in the request without their consent. Under Article 9(2), this safe conduct is a temporary right: it ceases if the witness voluntarily remains in the requesting state for more than 45 days after their presence is officially declared no longer required, or if they leave and subsequently return of their own free will.

Crucially, Article 9(4) preserves the right of a witness to decline to give evidence if either the law of the requested state or the law of the requesting state would permit them to do so in similar domestic proceedings. To resolve conflicts of law regarding this right, Article 9(5) establishes that a certificate issued by the central authority of one country stating that a right of refusal exists under its laws is conclusive proof of that fact for the courts of the other country.

The regulations do not contain direct, standalone criminal penalties. Instead, they function as an administrative conduit that allows domestic penal and enforcement mechanisms to be deployed on behalf of a foreign sovereign.

When Portugal makes a valid request under the Treaty, the enforcement of that request in Australia is carried out using the coercive powers set out in the parent Mutual Assistance in Criminal Matters Act 1987 (Cth). For example, if Portugal requests the search and seizure of property under Article 2, and the dual criminality requirement is satisfied, the Australian Attorney-General can authorize a police officer to apply to an Australian magistrate for a search warrant under the parent Act. Once issued, this warrant is executed by Australian police, and any failure by local citizens to comply with the lawful execution of that warrant is prosecuted under domestic Australian law, such as the Crimes Act 1914 (Cth).

In relation to the proceeds of crime, Article 10 provides for the domestic enforcement of foreign confiscation and restraining orders. If Portugal has obtained a confiscation order from a Portuguese court, Article 10(2) dictates that Australia must, if its laws permit, arrange for that order to be given effect. This is achieved by registering the foreign order in an Australian court under the parent Act, transforming it into an order that is executed as if it were a domestic forfeiture order.

Under Article 10(3), if Portugal merely signals its intention to seek a confiscation order, Australia is required to take interim protective measures, such as obtaining restraining orders, to prevent any dealing in, transfer of, or disposal of the targeted property. Financial institutions or individuals who violate these domestic restraining orders face severe domestic penalties, including prosecution for contempt of court or specific statutory offences related to the unauthorized dealing of restrained property.

For witnesses, Article 9(3) establishes that while a person present in the requesting state is immune from prosecution for past acts, they remain fully subject to the local laws of that state regarding perjury, the giving of untrue evidence, or an unlawful refusal to give evidence once they have agreed to appear. Thus, a witness who lies under oath in a Portuguese court after being transferred under this treaty can be prosecuted and imprisoned for perjury under Portuguese law.

The regulations exist within a complex web of domestic statutes, international treaties, and constitutional principles.

The primary interaction is with the parent Mutual Assistance in Criminal Matters Act 1987 (Cth). The regulations act as the trigger mechanism that unlocks the statutory powers of the parent Act in relation to Portugal. Section 7 of the Act permits regulations to apply the Act to a foreign country, and Regulation 4 dictates that this application is subject to the specific terms of the 1989 Treaty. Therefore, if a conflict arises between a broad power in the parent Act and a restriction in the Treaty (such as the exclusion of arrests or military offences), the restrictive terms of the Treaty prevail.

The regulations also interact directly with Australian domestic laws governing asset forfeiture and financial crime, principally the Proceeds of Crime Act 2002 (Cth) and its predecessor, the Proceeds of Crime Act 1987 (Cth). When a request is made under Article 10 to freeze or confiscate assets, the procedural steps, standards of proof, and court filings are governed by these domestic proceeds of crime statutes. This means that any foreign request must be translated into the domestic legal terminology of "restraining orders," "pecuniary penalty orders," or "forfeiture orders" under Australian law.

Furthermore, the regulations must interact with domestic laws governing police powers and judicial procedure, such as the Crimes Act 1914 (Cth) and the Evidence Act 1995 (Cth). Any physical search, electronic surveillance, or witness examination conducted in Australia to satisfy a Portuguese request must be performed in accordance with these domestic statutes. For instance, the admissibility of evidence gathered in Australia for use in Portuguese courts, or vice versa, will depend on whether the gathering process complied with the evidentiary standards of the receiving jurisdiction, as modified by Article 4's requirement that requests be executed in accordance with the law of the requested party.

Importantly, Article 16 establishes a non-derogation principle, ensuring that this Treaty does not displace other international obligations or treaties subsisting between Australia and Portugal. The treaty functions alongside, rather than instead of, other multilateral conventions to which both nations are party, such as the United Nations Convention Against Transnational Organized Crime, and does not prevent informal, police-to-police assistance through Interpol channels.

The Mutual Assistance in Criminal Matters (Republic of Portugal) Regulations, Statutory Rules 1993 No. 2411, have maintained a high degree of structural stability since they were first drafted and notified in the Commonwealth of Australia Gazette on 22 September 1993.

The regulations were made on 15 September 1993 by the Governor-General Bill Hayden, acting on the advice of the Federal Executive Council, with the executive command of the Attorney-General Michael Lavarch. Since their formal commencement on 17 October 1993, the text of the regulations and the scheduled Treaty has not been subjected to any substantive bilateral amendments or protocol updates.

This lack of legislative amendment is typical for bilateral mutual assistance treaties of this era. Such treaties are designed as broad, enabling instruments with flexible, open-textured language (for example, referring to "the law of the Requested Party" or "such measures consistent with its law") precisely to ensure they can accommodate ongoing changes to the domestic laws of both countries without requiring formal renegotiation of the treaty text.

Consequently, when Australia overhauled its domestic proceeds of crime regime by enacting the Proceeds of Crime Act 2002 (Cth) to replace the 1987 Act, or when it amended its domestic search warrant provisions in the Crimes Act 1914 (Cth), these changes automatically applied to requests executed under the Portugal Regulations. The reference in Regulation 4 and the scheduled Treaty to domestic enforcement mechanisms dynamically adapts to the current state of domestic law.

Administrative updates, such as the transition of the regulations to the Federal Register of Legislation and minor formatting consolidations under federal drafting acts, have occurred, but the core text of the treaty signed by Michael Tate for Australia and J. Fernando Nogueira for Portugal remains the governing law.

There is very little public litigation directly interpreting the Mutual Assistance in Criminal Matters (Republic of Portugal) Regulations. This lack of case law is a common feature of bilateral mutual assistance instruments, stemming from the administrative and executive nature of the process and the limited standing of private individuals to challenge state-to-state communications.

Under Australian administrative law, decisions made by the Attorney-General to domesticate a foreign request or to authorize the filing of warrant applications are executive acts. While these decisions are theoretically subject to judicial review under the Administrative Decisions (Judicial Review) Act 1977 (Cth) or section 39B of the Judiciary Act 1903 (Cth), Australian courts have historically adopted a highly deferential approach to executive discretion in matters involving international relations and cross-border law enforcement cooperation.

Litigation involving mutual assistance typically arises not as a direct challenge to the regulations or the treaty itself, but rather as a collateral challenge to the domestic enforcement measures taken to execute a request. For example, a target of an investigation might challenge the validity of a search warrant issued by an Australian magistrate on the basis of a Portuguese request, arguing that the warrant was too broad, lacked sufficient detail, or failed to comply with the strict conditions of the Crimes Act 1914 (Cth).

In such cases, courts apply general principles of mutual assistance law established in leading Australian authorities, such as Commonwealth v Director of Public Prosecutions. These cases establish that while domestic constitutional and statutory protections (such as judicial oversight of warrants) must be strictly maintained, courts should interpret mutual assistance treaties and their enabling regulations practically and purposively, seeking to facilitate international cooperation rather than defeating requests on minor technicalities.

Furthermore, because Article 10(5) protects the rights of bona fide third parties, litigation can occasionally arise in state or federal courts where commercial third parties seek to lift or vary restraining orders placed on corporate assets or bank accounts, arguing that their legitimate commercial interests are being unlawfully disrupted by a broad foreign investigation.

For legal practitioners, corporate compliance officers, and individuals, these regulations contain several hidden traps, or "gotchas," that can lead to severe procedural or commercial consequences if overlooked.

The first major gotcha is the strict temporal limit on safe conduct immunity under Article 9(2). A witness who consents to travel from Portugal to Australia (or vice versa) to give evidence is protected from arrest, prosecution, or civil suits for prior acts. However, this immunity is not a permanent shield. It expires precisely 45 days after the witness's presence is no longer officially required by the judicial authorities. If a witness remains in the country for personal reasons, holiday, or due to travel delays past this 45-day mark, they lose all safe conduct protections and can be immediately arrested or sued for past conduct.

The second gotcha is the "Conclusive Certificate" rule under Article 9(5). If a witness claims they have a right to decline to give evidence under the laws of the other state (for example, claiming a specific professional privilege or a privilege against self-incrimination unique to Portuguese law), a certificate issued by that other state's central authority is treated by domestic courts as "conclusive" proof of the foreign law. This completely strips the local court of the power to independently evaluate or hear expert arguments on the interpretation of the foreign law, potentially depriving the witness of a defence if the foreign certificate is drafted unfavourably.

The third gotcha relates to the "Retention of Confiscated Proceeds" under Article 10(4). Unless the two states specifically agree otherwise in a particular case, any proceeds of crime confiscated under the treaty are permanently retained by the requested state (the state that executes the forfeiture), rather than being returned to the requesting state or direct victims. This creates a distinct fiscal incentive structure where the domestic treasury of the country executing the seizure reaps the financial windfall, which can complicate negotiations regarding asset sharing or victim restitution.

Fourth, there is a strict 45-day notice requirement for serving witness summonses under Article 7(3). If Australia wants Portugal to serve a summons on a witness to appear, the request must be received at least 45 days before the scheduled appearance date. While this can be waived for urgent cases, failure to meet this timeline can result in automatic administrative refusal of the request, disrupting trial schedules.

Finally, the dual criminality disconnect in Article 2 means that while a target cannot block general intelligence gathering or witness interviews on the basis that the conduct is not an offence in the requested country, they can block physical search and seizure. Practitioners must carefully distinguish between the low threshold required for general assistance and the strict dual criminality threshold required for property searches.

Compliance with the regulations requires different actions depending on whether you are a corporate entity, a legal practitioner representing an affected party, or a government administrator.

For financial institutions, corporate trustees, and custodian entities, compliance is triggered when you are served with an Australian court order (such as a restraining order or search warrant) that has been issued to satisfy a Portuguese request. Upon receipt of such an order:

• Immediately freeze the targeted accounts or assets to prevent any dealing, transfer, or disposal, ensuring strict compliance with Article 10(3).
• Conduct a thorough internal review to identify any joint accounts, security interests, or third-party claims over the restrained assets, as Article 10(5) protects the rights of bona fide third parties.
• Strictly maintain the confidentiality of the request. Under Article 17(1), if the requesting state has asked for confidentiality, any unauthorized disclosure or "tipping off" of the account holder may constitute a serious domestic criminal offence.

For defense counsel representing a witness who has been asked to provide evidence or travel abroad under Article 7 or Article 8:

• Ensure that the client's consent is genuinely voluntary and documented in writing, as coercive measures and penalties are explicitly prohibited under Article 7(2)(c) and Article 8(4) for non-consent.
• Verify that "satisfactory arrangements for the security of the person" have been made by the requesting state under Article 7(2)(a).
• Advise the client on the precise date their presence is no longer required and ensure they depart the requesting state's territory well before the 45-day safe conduct immunity window expires under Article 9(2).
• If asserting a privilege or a right to decline to give evidence under foreign law, initiate contact with the foreign central authority immediately to negotiate the terms of any certificate to be issued under Article 9(5).

For central authority operators and prosecuting agencies drafting a mutual assistance request to Portugal:

• Ensure the request is signed by the designated Central Office (the Attorney-General's Department) and meticulously satisfies all structural requirements of Article 13, including a precise description of the assistance and a detailed statement of the acts constituting the offence.
• Comply with the language requirements of Article 15 by ensuring that all requests, supporting documents, and warrants are accompanied by a high-quality Portuguese translation.
• Observe the 45-day lead time required under Article 7(3) for witness summonses, or explicitly state the grounds for urgency if requesting a waiver.
