How Can Individuals Claim Reparation for Wartime Violations? A Seminar at the Pilecki Institute

On Friday, September 11, the Pilecki Institute hosted the seminar "Redressing Wartime Violations: How can individuals claim their right to reparation?" at its headquarters located at Sienna 82.

The seminar featured Dr. Norbert Wühler (Germany) and Prof. Aleksandra Mężykowska (Polish Academy of Sciences / Ministry of Foreign Affairs, Poland), both members of the Register of Damage for Ukraine (RD4U) and leading experts on claims, reparations, and property restitution. They explored the forums available for individual reparation claims and examined how current legal frameworks applied to historic conflicts like WWII. The event offered a unique opportunity to discuss the future of reparations with world-renowned specialists.

Discussion was moderated by Prof. Patrycja Grzebyk (Pilecki Institute / University of Warsaw).

Evaluating the procedural logistics of mass claims, Dr. Wühler analyzed processing methodologies developed by the United Nations Compensation Commission. – How you deal with 2.5 million claims within a reasonable time, in a reasonable way, in a fair way, that treats similar claims in a similar way – stated Dr. Wühler, identifying the operational necessity of claim categorization.

Addressing the distribution of limited compensation funds, the discussion focused on prioritization variables. – I would not go with a system where first in, first out would be the way to make payments because that, in my view, has a number of injustices compared to large parts of the claimant population, – asserted Dr. Wühler.
