Sadat Sayeed

Overview

Sadat’s practice particularly focuses on advice and representation in politically sensitive cases involving high-profile and senior figures from the worlds of politics, business and sport. The outcomes in these cases regularly impact upon the UK’s relations with other countries. Confidentiality prevents Sadat from identifying these individuals.

Sadat has acted for such clients from countries including the Russian Federation, Kazakhstan, Ukraine, Kyrgyzstan, Azerbaijan, Belarus, Georgia, Romania, Moldova, India, Egypt, Kuwait, Saudi Arabia, Libya, Syria, Jordan, Malaysia, India & Mexico. In these cases, Sadat provides initial strategic advice, he assists with the preparation of legally and evidentially complex applications (whether for asylum/human rights protection or for an immigration status) and provides representation before the immigration tribunals, the higher courts and the ECHR. Within the context of these cases, he has a specific interest in the interplay between extradition and asylum proceedings, with many of his clients simultaneously facing extradition and seeking asylum (as a result of abusive criminal proceedings being the preferred mode of persecution in these types of cases). Sadat’s practice also has an international dimension and his expertise in formulating political motivation arguments within extradition and international protection contexts is sought out across Europe.

Sadat has vast experience in helping clients to find innovative legal solutions to the most complex immigration situations. He has a deep understanding of the interaction of domestic immigration law (statute, Rules, guidance and case law), international legal instruments (UNCRC, EU law etc.), human rights law (domestic, ECHR and international), and political and policy considerations, and is able to deploy creative arguments on behalf of clients, both in the UK and abroad, who find themselves in difficult or novel situations. Sadat often advises such clients from the beginning of their legal journey, all the way through to the conclusion of litigation – these clients benefit, strategically, from engaging Sadat at an early stage, as he can ensure that critical evidential and legal markers are laid down at the very outset of the client’s contact with the Home Office (in the event that the case proceeds to litigation).

Sadat is one of a very small handful of barristers who have high-level experience in the UK immigration consequences of the imposition of sanctions, pursuant to the regimes created under The Sanctions and Anti-Money Laundering Act 2018 (“SAMLA 2018”). That act makes provision for a range of sanctions measures, including ‘travel bans’, which operate to deprive sanctioned individuals in the UK of their existing leave, or prevent such individuals outside the UK from entering. However, the exercise of these powers is subject to Refugee Convention and human rights protections, and the legislative scheme under SAMLA 2018 and the Immigration Act 1971 provides a framework for challenging (by way of an “immigration claim”) such travel bans, as well as an appellate remedy to the First-tier Tribunal, in the event they are maintained. These types of claims and appeals are rare and require an in-depth understanding of the UK’s sanctions regime. Sadat has acted for several high-profile clients who have been sanctioned, following Russia’s invasion of Ukraine in February 2022, in such claims and litigation.

Sadat also has a particular interest in the law relating to Article 8 ECHR and has a long track record of success in helping families to reunite and/or remain together in the UK. In this context, he has expertise in economic migration family life cases, refugee family reunion, entry clearance and leave to remain for partners and children, deportation, and the interplay between immigration and family court proceedings.

Sadat is a general editor of the current 11^th edition of Macdonald’s Immigration Law and Practice, the leading text in the field of immigration law, having also been general editor of the 10^th edition and a contributing author to the 6th, 7th, 8th and 9th editions.

Finally, Sadat provides advice and representation in respect of the full range of nationality law issues that arise under the British Nationality Act 1981, encompassing entitlements to British citizenship (including BOTC cases), discretionary registration of children, Commonwealth tracing cases, former diplomats/international organisation employees who were exempt from immigration control, and good character litigation. He is Assistant Consultant Editor of the British Nationality title in Halsbury’s Laws of England (5th edition).

Notable Cases

The majority of Sadat’s caseload involves high level advisory work in complex and sensitive protection claims, often for very high-profile individuals, meaning disclosure of the identities or content of these claims is not possible. Some of his notable cases can be seen below:

AB & DE v Secretary of State for the Home Department [2026: Upper Tribunal], [2025: First-tier Tribunal]
A three-week international protection appeal before the FTT – one of the longest in recent memory – in a case of the highest political sensitivity, concerning the rapidly declining human rights and democratic landscape of a close ally of the UK. The legal and evidential terrain of the appeal was vast, covering complex criminal (fraud) allegations, high level politics and foreign relations of the country in question, the inter-relationship between the protection claim and parallel High Court civil (fraud) proceedings, and the human rights situation in the country of return (in respect of which there was no extant country guidance). The FTT allowed the appeal and the Secretary of State appealed to the Upper Tribunal. Such was the legal and evidential complexity of the case, just the ‘error of law’ stage before the UT (listed before the President, Lavender J) was heard over five days.

NP & FS v Secretary of State for the Home Department [2026: First-tier Tribunal]
A three-day linked appeal before the FTT for two appellants from the Russian Federation. The first appellant was a prominent UK-based dissident; the second, a draft evader opposed to the conduct of Russia’s war in Ukraine. Sadat was involved in the underlying asylum claims from an early stage; just prior to the full hearing, the Secretary of State conceded the first appellant’s case and granted refugee status, and the second appellant’s appeal proceeded. In the absence of any recent country guidance, the FTT was required to conduct an intensive review of the latest evidence (including expert) on the human rights situation in Russia, as well as the conduct of the war in Ukraine (particularly evidence going to the commission of war crimes and crimes against humanity by Russia).

MA v Immigration Officer [2025]
The client was an award-winning, critically acclaimed international musician. He is one of the best-selling artists in the world with a dedicated global fanbase, however, he has had several criminal law related issues both in the UK and abroad, stretching back over a number of years. Sadat was initially instructed to advise the client in advance of the sold-out UK leg of his world tour (nearly 250,000 tickets sold for over £25 million) on the UK immigration consequences of his criminal history (most notably, his right to enter the UK, with reference to the SSHD’s power to refuse entry to those with criminal convictions). Later, Sadat was instructed to prepare an urgent out of hours application to the duty High Court judge for interim relief (to be followed by a judicial review claim) in the event the Immigration Officer refused the client entry to the UK, or granted him immigration bail, but without a condition permitting him to perform at his concerts. This was given the very significant economic loss that would ensue had he be not been so permitted (17,000 working roles; estimated £33 million additional revenue (beyond ticket sales) and £14 million in taxation and fees to HM Revenue & Customs). The client was permitted to enter and went on to perform his nine UK dates.

Sanctions cases – immigration claims and subsequent appeals [2022 to 2025]
On 15 March 2022, the UK imposed sanctions on three of Russia’s most prominent ‘oligarchs’. All three were resident in the UK with their families. The sanctions included immigration sanctions which have the effect of cancelling their immigration permission to live in the UK, and as a result, they would be excluded and banned from the UK. Sadat advised on the making of complex ‘immigration claims’, supported by extensive evidence, to the SSHD, challenging the imposition of immigration sanctions. Those claims were refused. Two of ‘oligarchs’ left the UK, but the third remained and exercised his right of appeal to the First-tier Tribunal. That appeal was going to examine the full range of complex and novel legal and evidential issues raised, but as a result of various factors, the appellant departed the UK before the appeal was finally heard and determined.

Middle Eastern royalty asylum claims [2018 to date]
Sadat has acted for several members of royal families from across the Middle East and Gulf in complex and diplomatically sensitive asylum claims. These claims have arisen in the context of disputes within those ruling families, often concerning succession issues or marriage breakdown. Almost invariably in such cases, the individual driving the alleged persecution is the monarch of the relevant country. In addition, these countries are usually allies of the UK, which inevitably adds diplomatic complexity to the Secretary of State’s decision making.

Chinese asylum claims – technology and surveillance [2020 to date]
Several international protection claims for high-profile Chinese nationals, arising out of the Chinese state’s continuing objective to ensure that all technology and surveillance innovations and companies are under its ultimate control.

Egyptian asylum claims post- Arab Spring [2011-16]
A series of asylum claims by prominent Egyptian politicians and businesspeople arising from the Arab Spring protests that saw President Hosni Mubarak deposed in 2011.

Russian asylum claims [2010, to date]
Numerous asylum claims and appeals by nationals of the Russian Federation who have, one way or another, fallen victim to the political machinations taking place at the highest level of Russian politics, often at the behest of President Putin and those within the Russian establishment who are entrusted to advance his political and economic objectives. Sadat has been involved in these cases for over 15 years, spanning various phases of Putin’s rule.

R (on the application of Immigration Law Practitioners’ Association) v (1) Tribunal Procedure Committee, (2) Lord Chancellor [2016] EWHC 218 (Admin), [2016] WLR 3519
Public interest challenge brought on behalf of the professional body of immigration lawyers challenging the legality of Rule 13 of the Tribunal Procedure (First-Tier Tribunal) (Immigration and Asylum Chamber) Rules 2014 which on its face gave the Tribunal the power to hold a closed material procedure in which evidence not disclosed to a party could be taken into account in the determination of an appeal.

Dmytro Firtash v United States of America – Regional Court, Vienna, Austria (30 April 2015)
Historic victory against an attempt by the USA to extradite Dmytro Firtash from Austria. In a landmark decision, the Regional Court in Vienna refused to order Firtash’s extradition on the ground that the US request was politically motivated.

R (on the application of Anam) v Secretary of State for the Home Department [2010] EWCA Civ 1140, [2011] ACD 14
Appeal from the Administrative Court on the question of the legality of detention under Immigration Act 1971, with particular reference to the failure of the Secretary of State to apply his own policy on the detention of the mentally ill. The court considered the Hardial Singh principles as interpreted in SK(Zimbabwe) and the causation test as interpreted in WL(Congo), and their impact upon the legality of the appellant’s detention.

YD (Togo) v Secretary of State for the Home Department [2010] EWCA Civ 214 [2010] Imm AR 446
Concerned with the impact of recent ECHR case law on the settled test for relocation within Article 8 ECHR, as clarified by the House of Lords in Huang, EB (Kosovo) and Chikwamba.

JA (Ivory Coast) v Secretary of State for the Home Department; ES (Tanzania) v Secretary of State for the Home Department [2009] EWCA Civ 1353, [2010] Imm AR 381
Lead test cases on the issue of what meaning and weight should the courts give, within the proportionality balance under Article 8 ECHR, to former grants of leave to HIV sufferers on the basis that the UK had ‘assumed responsibility’ for their HIV treatment.

AM & AM (armed conflict: risk categories) Somalia CG [2008] UKAIT 00091
Country Guidance case on risk for Somali returnees, route and method of return, internal armed conflict, international humanitarian law and Article 15(c) Qualification Directive.

O’Driscoll v Secretary of State for the Home Department [2002] EWHC 2477 Admin (Divisional Court), [2003] A.C.D. 35
Compatibility of s.16 of Terrorism Act 2000 with Articles 10 and 11 of ECHR.
