As a specialist in comparative administrative law, Przemysław Ostojski has published 7 books and about 100 articles in leading Polish, German, Austrian and Czech academic journals. His latest monograph is entitled: Standards of Judicial Review of Administrative Actions in the United States and the European Union. His research in this area was presented during the Visiting Scholar Program at the C. Boyden Gray Center for the Study of the Administrative State, George Mason University Antonin Scalia Law School (2021- 2022).

Przemysław’s education included studies at the Faculty of Law at Adam Mickiewicz University in Poznań (2004-2009), where he also received his doctorate in law (2014). He then completed his education in the United States and Belgium. His academic career began in 2013, when he started teaching at universities and conducting comparative research. In 2021-2022, he participated in three visiting scholar programs at American universities. In the same years he participated as a researcher in the Polish-Hungarian Research Platform project, analyzing the issues of administrative justice reform. In 2023 he was a guest at the University of Copenhagen.

Simultaneously with his academic work as a researcher and lecturer, he worked as a clerk at the Administrative Court in Poznań (Poland) for almost a decade (2009-2019), and then as a public prosecutor at the Prosecutor General’s Office in Warsaw (Poland), representing official statements of the Polish Prosecutor General before the Supreme Administrative Court in Warsaw (2019-2023).

Before and after obtaining his Ph.D. at Adam Mickiewicz University in Poznañ (Poland), he conducted comparative legal research on the enforcement of administrative court decisions in German-speaking countries (at the Institute of Federalism at the University of Fribourg, the Institute of Public Law at the University of Bern, the Institute of State and Administrative Law at the University of Vienna, the Institute of Public Law and Administrative Science at the Johannes Kepler University Linz, the Institute of Public Law and Administrative Science and the Institute of State Law and Administrative Science at the European University Institute in Florence; 2014-2018). At the same time, he worked on issues related to European legal principles and procedural fairness (due process) in administrative proceedings in Europe. The result of this research was the monograph: Instrumentalization of the Law on Administrative Proceedings, including interdisciplinary considerations on this subject – both within the European Union and in national legal systems. Based on his scientific achievements, by decision of the Council of the Faculty of Law and Administration of Adam Mickiewicz University in Poznań from 2018, he was promoted to the post-doctoral degree (habilitation) with venia legendi, becoming an independent researcher.

Thanks to cooperation with Judge Prof. Douglas Ginsburg, his research areas included judicial review and antitrust jurisprudence. The latter resulted in a chapter in a multi-author monograph on Judicial Review of Competition Cases, edited by prof. Douglas Ginsburg and Judge Tim Eicke KC (Concurrences, Paris 2023). He led the international research project “Regulating Big Tech” in cooperation with American and European economists and lawyers. His particular research interests are the so-called New Competition Law and the specificities of digital platforms, theories of harm and remedies in this area.
