About
Kapusuzoğlu:
A public law boutique
Our practice advises businesses in their dealings with public authorities in Turkey, with particular emphasis on the defense and litigation of tax, regulatory, and white-collar criminal cases.
We focus on economic activities involving governmental oversight. When businesses face challenges from tax authorities, regulatory agencies, or law enforcement, we provide the strategic counsel and courtroom advocacy needed to protect their interests.
Our firm is built on a unique combination of academic rigor and practical experience. We bring both scholarly expertise and frontline practitioner knowledge to every engagement, with established relationships across academia, government authorities, and the legal profession.
What We Do
Our firm focuses on three interconnected areas where public law meets commercial reality:
Tax & Customs – We represent clients in disputes with tax and customs authorities from initial inquiries through litigation. We handle inquiries, audits, voluntary disclosures, advance rulings, ADR, litigation, criminal defense and more across direct, indirect and customs taxation. Whether you face an audit, seek advance certainty on tax treatment, or need defense against allegations of tax or customs misconduct, we provide strategic counsel grounded in technical expertise.
Regulatory – We guide businesses through the complex landscape of regulatory compliance and enforcement. Our work spans cross-market regulations—including competition law, anti-corruption, data protection, and financial crime prevention—as well as sector-specific oversight in financial services, energy, telecommunications, healthcare, and e-commerce. When regulatory investigations arise, we stand by our clients at every step to protect their interests. We also counsel clients on government affairs and public policy matters, including litigation against governmental entities, public procurement, government contracting, and strategic advocacy on legislative and regulatory developments that affect their operations.
White Collar Crime – We defend individuals and corporations facing allegations of economic crime. Our criminal practice covers the full spectrum of white collar offenses, from tax and customs crime to fraud, market abuse, money laundering, corruption, and more. We represent both defendants seeking acquittal and victims pursuing justice and restitution. Beyond the courtroom, our reputation management practice coordinates legal and communications strategies during crises, pursues the removal of false or defamatory content, brings defamation actions when necessary, and seeks the expungement of criminal records.
Why It Matters
In an environment of intensifying enforcement and expanding regulatory reach, the margin for error has narrowed. A tax assessment can escalate to criminal prosecution. A regulatory inquiry can threaten a company's license to operate. A criminal allegation can destroy a reputation built over decades.
We help clients navigate these high-stakes moments with precision and resolve. Our approach combines technical expertise with practical judgment—we understand not only what the law requires, but how enforcement authorities think and act.
Why Us
Exclusive Public Law Practice – We have devoted our academic and professional careers solely to public law matters, developing comprehensive knowledge of how government power is exercised and contested. Our practice is grounded in PhD‑level scholarship in public law and a wealth of first-hand experience in disputes with public authorities.
Cross-Disciplinary Fluency – We possess integrated expertise across tax law, administrative law, and criminal law. This cross-disciplinary fluency provides a holistic public law perspective, allowing us to see how these areas of public law intersect and to anticipate how developments in one domain affect the others.
Bridging Multiple Worlds – With roots in both academic research and legal practice, and relationships spanning universities, government institutions, subject-matter specialists and the legal profession, we draw on diverse perspectives to solve complex problems. When matters require expertise beyond our own capabilities, our network enables us to connect clients with the right person.
