Tetevi’s practice encompasses all areas of criminal defence as well as appeals, inquiries and international law. He is regularly instructed in cases beyond his year of call and has a growing reputation for his well-crafted legal submissions and strategic thinking.
Recent instructions include appearing as a led junior in a widely-reported case of conspiracy to possess firearms with intent to endanger life. He also secured acquittals in a case of possessing false identity documents and fraud, and successfully appealed sentence in the Court of Appeal.
Tetevi has a particular interest in cases with a cross-border dimension. He is currently instructed in a multi-handed conspiracy to breach immigration law by several foreign nationals and is developing his terrorism and international investigations practices.
Beyond this, Tetevi advises individuals, organisations and states in matters of international law. He has worked at the International Criminal Court in The Hague, was a Visiting Scholar at the European Court of Human Rights and has recently provided advice to an NGO on the legality of a state’s death penalty practices.
Tetevi accepts instructions in both English and French.
Criminal Defence
Tetevi defends across the spectrum of criminal law from serious violence and human trafficking offences, to drugs and fraud offences. He has a busy and expanding Crown Court practice and also acts privately/certificate of counsel for defendants in the magistrates’ and youth courts.
Recent notable cases include:
R v Young (Tyrel) [2025] EWCA Crim 359 – Successful appeal against sentence in the Court of Appeal. The case concerned the correct approach to sentencing defendants who were youths at the time of an offence and the application of the principle of totality. A reduction in the Appellant’s sentence for several knife-point robberies led to his immediate release.
R v RBL & others – Led junior in a conspiracy to possess firearms with intent to endanger life involving high-profile music artists “Fredo” and “Digga-D”. The case involved complex legal arguments advanced in preparatory hearings on the limits and scope of the admissibility of “gangs” evidence.
R v HN & others (ongoing) – Junior alone in a multi-handed conspiracy to facilitate the commission of a breach of UK immigration law by several foreign nationals.
R v OG – successfully represented a defendant in a case of aggravated burglary. Following an application to exclude crucial evidence it was argued was obtained in breach of Police Codes of Conduct, the Prosecution offered no evidence.
R v LG & others (2024) – Acted as junior alone on behalf of one of seven defendants in a case of threatening to take revenge (witness intimidation).
R v AB (2024) – successfully represented a defendant charged with the possession of false identity documents and fraud by false representation (£50,000).
R v MG (2024) – successfully represented a defendant charged with attempting to commit grievous bodily harm with intent (s.18).
International Law
Tetevi has spent time at the International Criminal Court in The Hague where he was based in the Legal Advisory Section of the Office of the Prosecutor. In this capacity, he provided legal research on request to various divisions of the Court, including the Investigations Divisions and worked closely with the Court’s former Deputy Prosecutor.
He has also worked at the UN International Criminal Tribunal for the Former Yugoslavia. In this role, he worked closely with Judge Koffi Afande in the Court’s Appeal Chamber assisting him with legal research memoranda and opinions.
Tetevi’s work in international cases includes:
Prosecutor v Dominic Ongwen (ICC) – Landmark conviction of Dominic Ongwen, a former Commander in the Lord’s Resistance Army (LRA). Charges included 61 counts of war crimes and crimes against humanity, committed in Uganda between 1 July 2002 and 31 December 2005.
Prosecutor v Stanisic and Zupljanin (ICTY) – The Appeals Chamber confirmed the convictions and sentences of Mićo Stanišić, former Minister of the Interior of Republika Srpska, and Stojan Župljanin, former Chief of the Regional Security Services Centre of Banja Luka, Bosnia and Herzegovina (BiH) for war crimes and crimes against humanity committed in BiH in 1992.
Tetevi was recently instructed by Reprieve to provide a legal opinion to the Middle East and North Africa team on the status of the death penalty under international law. This opinion is being used as the basis for a submission to the UN Special Rapporteur on extrajudicial, summary or arbitrary executions.
Extradition
Tetevi is developing his extradition practice and has recently been instructed in a matter concerning the government of Romania and an individual who is wanted to serve a sentence of imprisonment for embezzlement and fraud. The Requested Person is resisting extradition on Article 8 (right to private and family life) grounds.
