Dear Collegues,

We would like to inform you that, due to the summer holiday period, the large number of registrations received in recent days, and numerous requests from prospective participants, the Organising Committee of the 4th Criminology Congress has decided to extend the registration deadline until 15 July 2026. No further extensions are planned.

We would also like to remind you that the 4th Criminology Congress, organised by the Professor Stanisław Batawia Polish Society of Criminology in cooperation with the Department of Criminology and Criminalistics of the Faculty of Law and Administration at the University of Warmia and Mazury in Olsztyn, will be combined with the formal celebration of the 70th birthday of Professor Wiesław Pływaczewski, organised jointly with the Police Academy in Szczytno.

The event will take place on 24–25 September 2026 at the Conference and Training Centre of the University of Warmia and Mazury in Olsztyn.

Yours faithfully,

The Organising Committee
