The Act establishes a legal immunity provision specifically targeting Polish citizens who fought alongside Ukrainian forces in the Russia-Ukraine armed conflict. The law creates a non-punishment framework, effectively shielding participating citizens from criminal prosecution or penalties arising from their involvement in hostilities on the Ukrainian side. This represents a substantive policy position by the Polish state regarding its citizens' involvement in the conflict.\n\nPolish citizens who participated in the conflict should be aware that this law provides formal protection against criminal consequences for their combat activities. The law was published in the Polish Official Journal (Dziennik Ustaw) on March 31, 2026, and is now in force. Legal practitioners and individuals affected should review the full statutory text to confirm the precise scope of immunity, any conditions attached, and any limitations on the protection.
