This document, dated July 22, 1978, is an official letter sent by Charter 77 spokespersons Ladislav Hejdánek, Marta Kubišová, and Jaroslav Šabata to the Soviet Ambassador in Prague, V. V. Mackevič. It expresses profound indignation regarding the sentences recently handed down to Soviet human rights defenders Aleksandr Ginzburg, Anatoly Shcharansky, and Viktoras Petkus. The authors assert that these individuals were convicted solely for monitoring Soviet compliance with the Helsinki Accords and informing international public opinion. Charter 77 draws parallels to their own experiences in Czechoslovakia, where the authorities often misinterpret legitimate civic efforts as 'anti-state activity' to intimidate the public and suppress dissent. The letter calls on the Soviet government to immediately release the three men and annul their sentences. The spokespersons frame this request as an act of justice necessary to improve the global political climate following the shock of the trials. The document highlights the significant transnational solidarity existing between human rights movements within the Eastern Bloc during the Cold War.
