Understanding the Legal Roadblocks That Can Stall or Stop Extradition Proceedings in 2025


Amicus International Consulting | Vancouver, Canada | July 6, 2025

Extradition remains one of the most contentious and misunderstood elements of international law. Behind the headlines of high-profile fugitives and diplomatic standoffs lies a complex legal principle that often determines the outcome of these cases: the principle of dual criminality. In practice, this principle can lead to lengthy delays, legal gray zones, and even failed extradition requests.

For governments seeking to bring suspects to justice, the dual criminality test is a legal standard that can either streamline or complicate the process of prosecution. For individuals facing extradition—whether rightly accused, wrongly charged, or politically targeted—it can be the very lifeline that prevents removal.

This Amicus International Consulting press release examines the legal, political, and procedural realities of extradition law in 2025, focusing on the critical role of dual criminality, its impact on delays, and the importance of understanding jurisdictional nuances when facing extradition risk.

What Is Dual Criminality?

Dual criminality is a legal requirement stating that an individual can only be extradited from one country to another if the alleged offence is recognized as a crime in both countries.

Example:
If a person is accused of financial fraud in Country A but the equivalent conduct is not a crime in Country B, extradition may be denied.

The doctrine ensures sovereign respect for legal differences and protects individuals from being removed for actions that are not illegal in their current jurisdiction. While simple in theory, the doctrine becomes highly complex when applied to:

  • White-collar crimes

  • Political speech

  • Tax evasion

  • Cybercrimes

  • Sexual conduct laws

Because these areas vary dramatically between countries, dual criminality is often a key battleground in extradition hearings.

How Dual Criminality Causes Delays

When a requesting country issues an extradition request, the receiving country must verify whether the crime meets the threshold for dual criminality. This process involves:

  • Legal interpretation of domestic law in both countries

  • Analysis of the factual basis for the alleged crime

  • Judicial review and appeals, sometimes to constitutional courts

  • Delays due to political intervention, particularly in cases involving asylum or human rights concerns

Even when treaties exist, the presence of dual criminality as a prerequisite can cause extradition cases to last months or even years.

Case Study 1: The Businessman Wanted for Insider Trading

In 2017, a Hong Kong-based financier was accused of insider trading and manipulating market positions. The charges, while severe under Hong Kong law, did not have an identical match under Swiss law, where he had relocated.

Despite Switzerland’s mutual legal assistance treaty (MLAT) with Hong Kong, the court found that Swiss financial regulations did not define the alleged activity as a criminal offence, only a regulatory infraction. Extradition was ultimately denied.

Result:
The financier lawfully remained in Zurich, and the case exposed deep legal gaps in cross-border financial law enforcement.

Treaty vs. No Treaty: What Changes?

Many believe that having an extradition treaty between two countries guarantees cooperation. In truth, it only establishes a framework, not an obligation.

In treaty nations, the principle of dual criminality remains a foundational principle. Even with a signed agreement, extradition can be denied if:

  • The crime is political

  • The offence doesn’t exist in both legal systems

  • The accused risks torture, death, or inhumane treatment

  • The judicial process lacks fairness

In non-treaty countries, extradition becomes a diplomatic matter, handled on a case-by-case basis, and is often influenced by international politics.

Expert Interview: Extradition Attorney Speaks on Legal Delays

Interviewee: International Extradition Defence Lawyer (Name Withheld)
Advises clients in Asia, Latin America, and Europe

Q: How often does dual criminality block extradition?
A: It’s one of the top three defences we use. Especially in white-collar crimes or internet-based charges, there are always differences in definitions. What one country calls “fraud,” another may view as a civil matter or business risk.

Q: Can clients stall extradition for years?
A: Absolutely. With a strong legal team, we can challenge the basis of the arrest, file constitutional appeals, argue human rights risk, and dispute dual criminality. One of our cases in South America has been pending for eight years.

Q: Does Amicus coordinate with legal teams to help clients avoid extradition risks?
A: Yes. They help identify low-risk jurisdictions and coordinate name changes, new residencies, and civil registration that align with the legal strategy.

When Extradition Is Denied: Legal Life After a Blocked Request

Individuals who survive an extradition challenge don’t always live freely afterward. Many faces:

  • Ongoing surveillance

  • Asset freezes in international banks

  • Travel restrictions (due to Red Notices or visa revocations)

  • Civil lawsuits in their new jurisdiction

  • Loss of banking privileges due to reputational risk

However, many work with consultants like Amicus to rebuild legal identities, establish new financial and residency structures and limit exposure to hostile jurisdictions.

Case Study 2: The Latin American Whistleblower

In 2019, a government employee from Colombia exposed illicit activity within a federal agency. Soon after, he was charged with “unauthorized disclosure of public information” and “espionage.”

He fled to Spain and sought asylum. Although Colombia and Spain have an extradition treaty, Spanish courts denied the request under the principle of dual criminality, arguing that the “espionage” charge lacked criminal equivalence under Spanish democratic law.

Outcome:
He was granted residency, requalified professionally, and remains protected from extradition.

Amicus Role: Pre-Extradition Risk Analysis

Clients working with Amicus often fall into two categories:

  1. Proactive Strategists: Individuals who foresee potential political or financial charges and relocate before arrest.

  2. Reactive Clients: Those facing current legal exposure seeking emergency residency, name change, or banking solutions.

Amicus provides:

  • Country risk mapping based on treaty law, Interpol cooperation, and legal definitions

  • Name change coordination that aligns with new jurisdictions’ civil and financial requirements

  • Digital footprint erasure to reduce visibility to surveillance or tracking systems

  • Banking and wealth restructuring to protect assets from asset freezes tied to extradition efforts

The Role of Interpol Red Notices

While not equivalent to an international arrest warrant, a Red Notice is a request to locate and provisionally arrest an individual pending extradition.

However, Red Notices are often politically abused, particularly by:

  • Authoritarian states targeting dissidents

  • Regimes silencing journalists

  • Governments retaliating against economic leaks

Interpol’s own review body has cancelled hundreds of Red Notices over the past decade, citing abuse of power and political bias.

Case Study 3: The Middle Eastern Journalist Exposed to Political Charges

In 2020, a female journalist from the Gulf region criticized her government’s censorship policies. She relocated to Germany, where she was met with an Interpol Red Notice alleging “financial misconduct.”

German courts examined the charges and concluded they were politically motivated and lacked dual criminality under German law. The extradition request was refused, and the Red Notice was challenged and eventually deleted.

She later relocated to Belgium under Amicus’ guidance, secured legal residency, changed her identity, and launched a freelance media career under a pseudonym.

Dual Criminality by Region: What to Know in 2025

RegionExtradition AttitudeKey Note on Dual Criminality
EU (e.g. Spain, France)Treaty-bound but cautious with political crimesStrong due process, EU human rights law considered
Latin AmericaHighly political; some countries reject InterpolNational laws are often inconsistent or outdated
Asia-PacificDepends on the relationship with China/USExtradition is rare without direct national interest
Middle EastLow extradition to/from Western statesReligious or moral crimes often clash with Western law
AfricaOn a case-by-case basis, some non-cooperative jurisdictionsOften lack treaties, but regional blocs influence

The Future: Extradition in a Biometric and AI Age

In 2025, the growing use of biometric surveillance and automated profiling may render physical relocation less effective unless paired with a comprehensive identity transformation.

Authorities now use:

  • Facial recognition systems at borders

  • AI to match writing and speech patterns online

  • Automated visa denials based on watchlists

  • Financial AI to flag transfers linked to known suspects

Thus, escaping extradition will require deeper privacy architecture, not just new names or locations. Amicus supports this through its full-suite legal and digital restructuring services.

Final Thoughts: Delay Is Not Defeat—But It Requires Strategy

Extradition is not automatic. Dual criminality and procedural fairness remain strong defences, even against powerful nations. However, delays are only effective when paired with strategic legal tactics, jurisdictional awareness, and asset protection.

Amicus International Consulting works with clients to ensure that, even under legal pressure, they remain empowered. Through lawful relocation, identity realignment, and cross-border analysis, Amicus helps those under threat secure a stable, legitimate future.
