How a Rule of Specialty Extradition Lawyer Protects You from Unauthorised Prosecution

When a person is extradited, the requesting state may prosecute them only for the offences for which extradition was granted — not for additional charges discovered or invented later. This treaty-based limitation is the principle of specialty. Violate it, and you trigger diplomatic disputes, motions to dismiss, and international legal challenges. A specialty extradition lawyer analyses the treaty text, surrender decision and diplomatic consent to ensure prosecution stays within approved boundaries.

Principle of specialty is a binding treaty rule prohibiting a requesting state from prosecuting, sentencing or detaining an extradited person for any offence committed before surrender other than those for which extradition was granted, unless the surrendering state consents or the extradited person fails to leave within 45 days of discharge (European Convention on Extradition, Article 14; Inter-American Convention on Extradition, Article 13).

Our legal team has defended clients in specialty disputes across 28 jurisdictions. We coordinate with counsel in the United States, United Kingdom, Canada and European Union member states. We challenge post-extradition prosecution exceeding the scope of extradition orders, review treaty language for waiver clauses, and secure dismissals when requesting states breach diplomatic limits.

Key Takeaways

• The rule of specialty protects extradited persons from prosecution for offences not listed in the extradition grant. It appears in Article 14 of the European Convention on Extradition and Article 13 of the Inter-American Convention. Violate this and you’re facing dismissal motions with real teeth.
• Exceptions do exist: if the extradited person stays put for 45 days after discharge without leaving, consents to broader prosecution, or commits new offences post-surrender, specialty protections evaporate. Each exception has its own traps.
• The U.S. Foreign Affairs Manual (7 FAM 1610) confirms the rule applies in “virtually all extradition treaties” and requires prosecutors to respect diplomatic limits. Prosecutors who ignore this face motions they cannot easily win.
• Violations trigger motions to dismiss based on treaty breach. Remedies range from case dismissal to diplomatic intervention by the surrendering state. A single prosecution beyond specialty scope can collapse an entire case.
• We review treaty text, surrender warrants and consent documentation to identify specialty violations before prosecution begins. Early detection saves months of litigation.

What Is the Rule of Specialty in Extradition Law?

Specialty is a treaty-based restraint preventing a requesting state from prosecuting an extradited person for crimes other than those approved in the extradition order. Article 14 of the European Convention on Extradition states that an extradited person “shall not be proceeded against, sentenced or detained… for any offence committed prior to his surrender other than that for which he was extradited,” unless the surrendering state consents or the person remains 45 days after release without departing. The same rule appears in Article 13 of the Inter-American Convention on Extradition, which prohibits detention, trial or punishment “for an offense… other than that for which extradition has been granted” absent explicit consent.

How does the U.S. interpret this? The U.S. Foreign Affairs Manual (7 FAM 1610) defines specialty as “a principle, reflected in virtually all extradition treaties, under which the requesting state may… prosecute or punish the fugitive only for the crime or crimes for which extradition was granted, subject to certain exceptions.” The U.S. Department of Justice internal guidance (JM-9-15.000) requires extradition requests to include “copies of the statutes alleged to have been violated” and evidence establishing the crime. This ensures prosecution aligns with charged offences under specialty — or at least, that’s the intent when the system works.

Why Does the Rule of Specialty Exist?

Specialty balances sovereign interests of the requesting state with individual rights of the extradited person. Without it, bait-and-switch becomes standard practice: a requesting state requests extradition for a minor charge, secures custody, then prosecutes for major undisclosed crimes. Specialty prevents this. It maintains trust between treaty partners: a surrendering state releases custody expecting the requesting state will prosecute only for offences described in diplomatic notes and judicial surrender orders. Council of Europe explanatory notes to the European Convention confirm that specialty preserves “the balance between mutual assistance and protection of individuals.”

The practical stakes are high. Without specialty, requesting states exploit cooperative frameworks with impunity. The rule ensures diplomatic consent governs the scope of prosecution, not unilateral decisions by prosecutors thousands of miles away.

How Does a Specialty Extradition Lawyer Protect Clients?

Lawyers specialising in specialty issues perform treaty analysis, consent review and scope verification before and after extradition. We examine the bilateral or multilateral treaty between the surrendering and requesting states, identify specialty clauses and exceptions, and compare approved extradition offences with the charges now filed. If prosecutors attempt to charge pre-extradition offences not covered in the original extradition request, we file motions to dismiss based on treaty breach.

We coordinate with counsel in the surrendering state to confirm whether that state consented to expanded prosecution. UK Extradition Act 2003, Sections 53–57, describes specialty as a “long-standing protection” with statutory exceptions. If the United Kingdom surrendered your client, we review whether the Home Secretary issued consent under Section 55 before any additional charges were filed. In European Union cases, we analyse Framework Decision 2002/584 specialty provisions and any post-surrender consent recorded by the executing judicial authority.

When the United States is the requesting state, we monitor compliance with 7 FAM 1610 and challenge violations in federal district court. When the requesting state is an Organization of American States member, we invoke Article 13 of the Inter-American Convention and seek intervention by the surrendering state’s Ministry of Foreign Affairs.

When Should You Hire a Specialty Extradition Lawyer?

Engage counsel during initial extradition proceedings to ensure charges are properly documented and limited. If the extradition order lists only fraud offences but post-surrender indictments add money laundering or conspiracy, a specialty violation exists. Here’s when to hire immediately:

• The requesting state files charges for offences not listed in the extradition warrant. This is the clearest sign of violation.
• Prosecutors attempt to prosecute for crimes committed before surrender but discovered afterward. Timing matters enormously.
• You face re-extradition to a third country without the original surrendering state’s consent, violating IGAD Convention on Extradition provisions.
• The surrendering state denies or delays consent for additional charges, yet prosecution proceeds anyway.

Early intervention lets us file specialty objections before trial. This preserves treaty defences and avoids waiver — and it avoids the far costlier scenario of litigating specialty after conviction.

What Are the Exceptions to the Rule of Specialty?

Specialty is not absolute. Four recognised exceptions permit prosecution beyond the original extradition grant. Know them. They are the escape routes prosecutors will attempt to use.

Consent Exception

After extradition is complete, the surrendering state may explicitly authorise prosecution for additional offences. Under Article 14 of the European Convention, consent must travel through diplomatic channels — typically a formal request from the requesting state’s Ministry of Justice to the surrendering state’s competent authority. UK Extradition Act 2003, Section 55, requires the Home Secretary’s written consent before a person extradited from the UK can be prosecuted for offences not specified in the original extradition order.

Consent is not automatic, and surrendering states regularly refuse it. The surrendering state reviews the new charges, assesses whether they satisfy dual criminality and treaty requirements, and may refuse consent if the additional offences are political, fiscal or military in nature. We review consent documentation to ensure it is valid, timely and covers the specific charges filed. Many prosecutors assume consent is implied or forthcoming — it rarely is.

45-Day Departure Rule

If an extradited person remains in the requesting state for 45 days after discharge without leaving, specialty protections lapse. Article 14 of the European Convention and UK Extradition Act 2003, Section 54, codify this rule. The 45-day period begins when the person is discharged from custody and free to depart — not from conviction or sentence completion.

From practice: Clients often assume specialty protection ends upon release. It doesn’t. The 45-day clock starts only when you are actually free to leave and have not done so. Continued detention, immigration holds, or legal restrictions reset the clock or stop it entirely.

If the person is held on unrelated charges, subject to immigration detention, or otherwise unable to depart, the 45-day period does not run. We verify the discharge date, review travel documentation, and establish whether the client had a genuine opportunity to leave. The difference between “could have left” and “was actually free to leave” can determine the entire case.

Same-Fact Offences

Requesting states may prosecute for crimes arising from identical conduct described in extradition documents, even if charged under a different statute. Extradition granted for “fraud by false representation”? Prosecutors may charge “obtaining property by deception” if both offences rest on the same factual allegations. 7 FAM 1610 confirms that specialty permits prosecution for offences “based on the same facts as those on which extradition was granted.”

This exception is narrowly construed. Prosecutors cannot add unrelated factual allegations or expand the scope of conduct beyond what was documented in the extradition request. We compare the original extradition documents — diplomatic notes, warrants, affidavits — with the new indictment to determine whether the factual predicate is truly identical. Often, it isn’t. Prosecutors stretch the bounds of “same facts” regularly, and those stretches fail under scrutiny.

Post-Extradition Offences

Crimes committed after arrival in the requesting state fall outside specialty protections entirely. If the extradited person commits theft, assault or any offence following surrender, those charges are not subject to the rule of specialty. The limitation applies only to pre-extradition conduct.

Prosecutors must establish the timing of alleged offences relative to the extradition date. We examine evidence, review discovery materials, and challenge claims that post-surrender charges rest on pre-surrender conduct. The distinction between “what happened before arrival” and “what happened after arrival” is factual, verifiable, and often contested.

How Do International Treaties Define the Rule of Specialty?

Treaty / Instrument	Specialty Clause	Exceptions Recognised
European Convention on Extradition, Article 14	Prosecution prohibited “for any offence committed prior to surrender other than that for which he was extradited”	Consent; 45-day departure; same-fact offences; post-surrender crimes
Inter-American Convention on Extradition, Article 13	Person “shall not be detained, tried or punished… for an offense… other than that for which extradition has been granted”	Consent; 45-day departure; same-fact offences
U.S. Foreign Affairs Manual, 7 FAM 1610	Requesting state may “prosecute or punish the fugitive only for the crime or crimes for which extradition was granted”	Consent; departure-based waiver; same facts
UK Extradition Act 2003, Sections 53–57	Prosecution for “extradition offence for which he was extradited” only, unless exceptions apply	Consent (Secretary of State); 45-day departure; same-fact offences; post-surrender crimes
IGAD Convention on Extradition	Person “shall not be proceeded against, sentenced, detained, re-extradited… for any offence committed before surrender” except as granted	Consent; departure-based waiver; same conduct

What this means: Every major extradition framework protects you with nearly identical language—but the actual shield depends on which treaty governs your case and whether the surrendering state has agreed to let prosecutors go beyond the original charges. The treaty text is your contract. Treat it that way.

How Does the Rule of Specialty Apply in European Extradition Cases?

Article 14 enforcement flows through the Council of Europe and the European Court of Human Rights. When EU member states execute European Arrest Warrants under Framework Decision 2002/584, specialty protections stay locked in. The executing state’s judges can demand that the issuing state list all approved offences directly in the warrant itself.

What actually happens: requesting states file supplementary requests asking for consent to prosecute offences discovered after surrender. The surrendering state’s competent authority reviews the new charges, confirms they’re crimes in both jurisdictions, and either approves or denies via diplomatic channels. Prosecute without this consent, and you’ve breached Article 14—which can trigger Council of Europe complaints or the surrendering state’s Ministry of Justice demanding intervention. That’s a real consequence, not a technicality.

Does the United States Enforce the Rule of Specialty?

Yes. U.S. federal courts take specialty seriously. Defendants move to dismiss when prosecution drifts beyond what the extradition order allowed, and courts examine the warrant, surrender order, and treaty to see if the new charges fit.

Behind the scenes: the Department of Justice has internal policy (JM-9-15.000) requiring prosecutors to respect specialty limits and pull consent from the surrendering state before adding charges. Break this rule and you face charge dismissal, a diplomatic row, and future refusal by other countries to extradite anyone to the U.S. That last one—refusal to cooperate—is the real hammer.

Why Specialty Violations Often Go Unchallenged

Most extradited persons don’t realize they have specialty protections until prosecutors file additional charges. By then, time and momentum work against them. Legal aid counsel in requesting states frequently lack expertise in international extradition law—they may skip treaty review entirely or assume specialty was already waived. Private defence counsel struggles differently: they often can’t access extradition documents or diplomatic correspondence, leaving them unable to prove treaty violations even when they suspect one.

We fill this gap. Our approach involves coordinating with counsel in the surrendering state, obtaining extradition records, and conducting treaty analysis before prosecution advances further. If you were extradited under a multilateral convention—the European Convention on Extradition or the Inter-American Convention—we identify which state parties are bound, review explanatory reports, and cite case precedents from the European Court of Human Rights and inter-American human rights bodies. This matters practically because it determines which courts have jurisdiction to hear your challenge and which precedents carry weight.

Canada–U.S. extradition cases require particular attention. We work with Canada extradition lawyers to confirm whether the Canadian Minister of Justice issued consent for expanded prosecution under the bilateral treaty. For persons extradited from IGAD Convention jurisdictions, we review regional treaty obligations and coordinate with counsel in member states to challenge re-extradition or unauthorized prosecution.

Specialty and Re-Extradition to Third Countries

Specialty has a second, equally important dimension: it prohibits re-extradition to a third country without the original surrendering state’s consent. The chain works like this—you’re extradited from State A to State B. State B cannot then transfer you to State C without A’s authorization. Article 15 of the European Convention on Extradition and IGAD Convention provisions make this explicit.

We challenge unauthorized re-extradition through habeas corpus petitions, diplomatic intervention requests to the original surrendering state, and treaty violation arguments in the requesting state’s courts. If extradition and red notice in Turkey led to your initial surrender, we verify whether Turkey consented to onward transfer—and if it didn’t, we seek either your return to Turkey or charge dismissal in the third country.

How Courts Interpret the Rule of Specialty

Judges take specialty seriously. Federal courts in the United States, the European Court of Human Rights, and courts across Organization of American States member states interpret specialty narrowly, prioritizing individual rights over prosecutorial convenience. Several principles dominate their reasoning:

• Strict compliance required. Requesting states must prove charges fall within the approved extradition scope. When documents are ambiguous, courts rule in your favor.
• Consent must be explicit. Implied or constructive consent doesn’t count. The surrendering state needs to issue formal written authorization.
• Same-fact offences stay narrowly defined. Prosecutors cannot relabel conduct or expand charges beyond what the extradition documents described.
• Waiver demands informed consent. You must knowingly and voluntarily waive specialty protections. Coerced or uninformed waivers are invalid—and courts scrutinize them heavily.

We cite precedents from these jurisdictions to support specialty challenges and document treaty violations with specificity.

Specialty and Plea Negotiations

Prosecutors offer plea agreements that come with a hidden cost: waiver of specialty protections. The deal sounds simple—plead guilty to something, and in exchange, specialty disappears. That opens the door to prosecution for any pre-extradition offence, regardless of whether it was disclosed to the surrendering state. This is dangerous territory. Once you waive specialty, you cannot reclaim it.

Before signing anything, we take these steps:

• Read the proposed plea agreement for waiver language—the language is often buried in boilerplate;
• Calculate the actual risk of additional charges if specialty protections vanish;
• Negotiate limits on waiver scope or extract prosecutorial assurances in writing;
• Consult with counsel in the surrendering state about diplomatic fallout.

Counterintuitively, refusing to waive specialty sometimes strengthens your negotiating hand. Prosecutors may lack evidence for same-fact offences or realize they cannot obtain the surrendering state’s consent. That weakness becomes your leverage.

Frequently Asked Questions

What is the rule of specialty in extradition law?

Specialty is a treaty-based shield: it prevents a requesting state from prosecuting you for offences other than those named in the extradition order. Article 14 of the European Convention on Extradition and Article 13 of the Inter-American Convention establish this rule. The surrendering state must explicitly consent before any additional charges proceed. Specialty exists because it gives countries confidence that extradition won’t be used as a backdoor to prosecute political opponents or unrelated crimes.

Can a requesting state prosecute me for offences not listed in the extradition order?

No—unless one of four narrow exceptions applies. You’re protected unless the surrendering state consents in writing, you voluntarily remain in the requesting state for more than 45 days after discharge without trying to leave, the new offences rest on identical facts described in the extradition request, or you commit a brand-new crime after surrender. Prosecution outside these exceptions violates specialty and may result in charge dismissal.

What are the exceptions to the rule of specialty?

Four recognized exceptions permit expanded prosecution: (1) written consent from the surrendering state, (2) failure to depart within 45 days of discharge, (3) same-fact offences arising from conduct described in the extradition request, and (4) new offences committed after surrender. Each exception requires documented proof and strict treaty compliance. Courts read these exceptions narrowly.

How do I challenge a specialty violation?

File a motion to dismiss based on treaty breach. Attach the original extradition documents, show that charged offences fall outside the approved scope, and provide evidence that the surrendering state withheld consent. Remedies include dismissal of charges, suppression of evidence obtained in violation of specialty, and diplomatic intervention by the surrendering state.

Does the 45-day rule apply if I am detained after extradition?

No. The 45-day period begins only when you’re actually discharged from custody and free to leave. Continued detention, an immigration hold, or any circumstance preventing your departure resets the clock. Courts interpret this strictly—prosecutors must prove you had a genuine, realistic opportunity to depart.

Can the requesting state re-extradite me to a third country?

Not without the original surrendering state’s written consent. Unauthorized transfers violate specialty under Article 15 of the European Convention on Extradition and IGAD Convention provisions. We challenge such transfers through habeas corpus petitions and diplomatic intervention requests.
